Chapter Twelve.The Secret of the Ribbon.Our new discovery seemed to me so remarkable that I lost no time in impressing upon Madame Gabrielle the imperative necessity of the closest possible scrutiny of Blind Heinrich’s actions. I was more than anxious that we should not lose sight of him for an instant, and that I should be kept fully informed of his every action. For by this time I was firmly convinced that, through some medium which we had yet to discover, he was in some way keeping up communication with the more active agents of the enemy. And if we could but discover the channel through which the stream of communications flowed, it would not be long, I felt sure, before we had the key to the mystery in our hands.Suddenly, and without any obvious reason, Heinrich completely changed his habits. Hitherto always on the move, he took to remaining indoors all day, hardly ever going out except for a short stroll in the evening. He met no one and apparently spoke scarcely a word to anybody. What his numerous pupils thought of his sudden neglect of them I cannot say. But it was clear enough that something important must have occurred to induce him thus suddenly to abandon what was, professedly at any rate, his sole means of livelihood.I was discussing him—he was almost invariably our sole topic of conversation nowadays—with Madame Gabrielle as she sat in my room one morning.“I cannot conceive of any reason,” I said, “why Heinrich should have so suddenly changed the entire routine of his existence. It looks to me as though either something very important has happened or that he is expecting important news. Yet he receives no messages; he never gets even a letter or a telegram.”“There is only one fact that is peculiar,” said the smart Frenchwoman. “You know I have been looking after him pretty closely lately. Well, whenever he goes out, though he appears to wander about quite aimlessly, he invariably contrives his walk so that it takes him through Lembridge Square. He never misses.”“Does he always go the same side of the Square?” I asked.She replied in the affirmative, and I decided to have a look round the Square for myself at once.That same afternoon found me on the scene of Blind Heinrich’s daily walk. The Square itself varied little from hundreds of others in London: it showed every evidence of dreary respectability common to half the squares in London. Two things, however, attracted my notice.In the ground-floor window of one house was a big brass cage containing a grey parrot, which was insistently emitting the hideous noises common to the parrot tribe. In a similar window about a dozen houses away was a case containing some old-fashioned wax flowers beneath a glass dome, evidently a survival from the ornamental style peculiar to the early Victorian epoch to which, indeed, the whole dreary Square seemed to belong.There was nothing to offer a lucid explanation of why Blind Heinrich should choose such a path for his daily ramble. There were dozens of other far more attractive promenades within easy walking distance. Yet here, unless my instinct entirely misled me, was the solution to our riddle.Day after day I followed the old fellow’s route. I even went so far as to shadow Heinrich himself more than once and verified Madame Gabrielle’s observation. No matter which way he started out, he never failed, on either the outward or homeward journey, to pass along that particular side of the Square. Yet he never spoke to anyone, and I was morally certain that no signal was ever made to him from any of the houses.On the fourth day I noticed a slight fact. The ring on the top of the parrot’s cage was tied with a big bow of yellow ribbon. Three days later it was altered to dark blue. On the eighth day it had returned to yellow again.Why these changes? Were they signals?That night enemy aircraft crossed the south-east coast, but their attempts to reach London were defeated by the terrific fire of the anti-aircraft guns and by a swift concentration of our fighting aeroplanes, which broke up several successive squadrons, and sent the raiders hurrying home again.Several of my capable assistants then took over the task of finding out all that was known regarding the house in Lembridge Square. Forty-eight hours later I had a full report. I learned that the man in whose room the parrot lived was one of the mysterious band who foregathered to meet Kristensten in the empty house in Harrington Street. He was then dressed as a special constable, a part which, by the way, he had no right whatever to play. He bore the thoroughly English name of Mostyn Brown, and was in business in the City as the agent of a Manchester firm of cotton merchants. Apart from the fact of his presence that night in Harrington Street, nothing that the most exhaustive inquiries revealed suggested in the smallest degree any association with agents of the enemy. To all appearances he was a perfectly respectable City man, in no way different from thousands of others. But—there was a very big but: what was his business in the dead of night in an empty house in the West End in company of a suspected German spy?A few days later the men who were keeping the houses in Lembridge Square and Hereford Road under surveillance sent me a strange report, which set me thinking deeply. By some means—whether he suspected he was being watched or whether a lucky chance favoured him, we never knew—Blind Heinrich managed to elude the unwearying vigilance of Madame Gabrielle and arrived alone, evidently in a hurry, at Westbourne Grove. Here he hailed a taxi and was driven to Waterloo Station. There at the booking-office on the loop-line side he had met a short, fat man, to whom, after a brief conversation, he handed a bottle wrapped in white paper. They remained in conversation a few minutes longer and then parted. The fat man was followed to the tube railway and thence to King’s Cross, where he had bought a ticket for Peterborough, and left by the five-thirty express.Why Peterborough, I wondered? There were certainly no facilities there for anyone engaged in Germany’s nefarious work. But attached to the report was a snapshot—taken secretly, of course—which showed me at once that the little fat man was apparently a sailor, “camouflaged” hastily in a badly fitting overcoat and a cloth cap. That gave me a further clue. I took down a Bradshaw, and, glancing at the train by which the little fat man had travelled, made an interesting discovery. It was the Newcastle express. I began to see why the mysterious little man had booked to Peterborough. That afternoon I ascertained that the parrot’s cage in the house in Lembridge Square sported a broad ribbon of yellow satin. At midnight I rang up Hecq at his house at St. Germain, and asked him to send Aubert the detective over at once.An hour after midnight came another air-raid alarm—the second to coincide with the appearance of the yellow ribbon.Now one coincidence of this kind may mean nothing. Two begin to be suspicious. A third is convincing. I found my suspicions deepening into certainty.Directly the air-raid warning was given, our watchers in Harrington Street were keenly on the alert, but, though they watched all night, there was no meeting of the mysterious men in the empty house. I guessed the reason. The raiders were again driven back before they could reach the Metropolis, and, therefore, there was no news to be gathered for transmission to the authorities in Berlin. Everything now pointed with increasing certainty to the house in Lembridge Square as a focus of enemy activity.Directly the “All clear” had been sounded over the London area, Heinrich left Hereford Road, and, according to Madame Gabrielle’s report to me, hurried round to the house of the grey parrot. He remained there about half an hour, and then retraced his steps home in the waning moonlight.Thus mystery followed mystery. What was the meaning of the various coloured bows on the parrot’s cage? For that they had a very definite meaning I no longer doubted. It seemed, indeed, tolerably clear that the yellow ribbon betokened a coming raid. And evidently the half-blind old musician was a close friend of the manufacturers’ agent. But who, in reality, was the mysterious Mostyn Brown, and, if he were indeed an enemy agent, how had he managed to elude the close watch that had been set upon him?It had struck me that the house which sheltered the grey parrot might conceivably conceal a wireless plant of sufficient power to convey a message to a submarine lurking off the coast. Such a plant need not be a conspicuous affair. But one of my agents, posing as an official of the Metropolitan Water Board, had been able to negative the suggestion, and I confess I found myself still hopelessly puzzled as to the means by which information of the damage done by the raiding aircraft was so speedily and so accurately conveyed to the enemy.By this time Aubert had arrived from Paris, and had taken an obscure lodging in Chessington Street, a dingy thoroughfare off the Euston Road. By appointment I met him late one night at the corner of Grey’s Inn Road and Holborn, and, having explained to him briefly what had occurred, told him to hold himself in readiness for instant action.The apparent abandonment of the secret meetings in Harrington Street was a source of considerable anxiety and chagrin. I was particularly anxious about them. We had several of those who had taken part in the first meeting under close observation, but had learned nothing about them sufficient to justify our taking strong action. Most of them, indeed, seemed to be of the same apparently blameless type as Mr Mostyn Brown, and it was evident that if they were indeed enemy agents they had been selected or appointed by a master-hand at the game of espionage. And I wanted badly to gain some more information about them.Madame Gabrielle was ever on the alert, and soon it appeared from her report that the blind fiddler was expecting another raid. The ribbon bow on the parrot’s cage changed to dark blue, and remained so for six days. On the seventh it was replaced by yellow. That night the old man remained in his room reading for hours after all the other inmates had retired. But that night no raid was made.I now began to think that it would be well if I took the mysterious Mostyn Brown under my own special observation. For a week during the moonless nights I shadowed him closely. I found out that he was a member of a certain third-class City club, frequented by a large number of “pure-blooded Englishmen” who happened to bear German names—of course they had been naturalised—and very soon my name appeared on the club books.It was not long before I managed to scrape acquaintance with Mostyn Brown over a game of billiards. I cultivated his friendship eagerly, and very soon we were on excellent terms. As a matter of fact, I wanted an invitation to his house, and at last I got it.I spent there one of the dullest evenings of my life, an evening, as it happened, entirely wasted. Beyond noting that the ribbon on the parrot’s cage had again turned to blue, I saw nothing of the slightest interest.The next night, however, I made a discovery. Dropping in at the club, I found Mostyn Brown engaged in a game of billiards with a man whom I knew in the club as Harry Smith. A bullet-headed, bespectacled person, with hair standing erect as the bristles of a blacking brush, Smith looked the typical Hun, and I very soon decided in my own mind that Heinrich Schmidt was probably the name by which he was first known to the world.Suddenly a dispute arose about some point in the game, and in a moment words were running high. Half a dozen spectators noisily joined in the altercation, and the room was a Babel of dispute. I saw my chance.Taking Mostyn Brown’s side, I suddenly interjected a sentence in German. Apparently hardly noticing the change in his excitement Mostyn Brown replied in the same language, and his accent told me at once that he was not of British birth. There was no possibility of mistake, for, however well the Hun may speak our tongue, he will inevitably betray himself when in a moment of excitement he lapses into his own language.My suspicions of Mostyn Brown were naturally intensified a hundredfold by this discovery. Of course, I redoubled my efforts, and was in daily conference with certain highly placed people in Whitehall, whose curiosity was now fully roused, as well as with my own agents, the vivacious Madame Gabrielle and the slow, but painstaking and relentless, Aubert. The watch on the suspects became closer than ever, and I was convinced that, try how he might, none of them could move, practically speaking, without full details of what he was doing reaching me in the course of an hour or two at most. And I was ready to strike hard at the earliest moment when decisive action might seem justified.For the moment, however, there was nothing to be done but watch and wait, tense and expectant, while night by night the moon drew nearer and nearer to the full. Thanks to the information I was able to place before the authorities in Whitehall, there was little chance of the anti-aircraft defences of London being caught napping, while the secret signal I had discovered—the changing of the coloured ribbon on the parrot’s cage at Mostyn Brown’s house in Lembridge Square—would be almost certain to give us warning of any long-arranged raid in force. Apart from the sequel, the worst we had to expect was a sudden dash by a few machines in the event of an unexpected improvement in the weather rendering such a course possible. But with regard to the big raids, involving days of patient preparation, settled weather, and most careful and thorough organisation, we felt tolerably sure that the tell-tale ribbon would give us the warning we wanted. So it proved in the event, and once again the Hun’s trickiness brought his carefully planned scheme to failure.
Our new discovery seemed to me so remarkable that I lost no time in impressing upon Madame Gabrielle the imperative necessity of the closest possible scrutiny of Blind Heinrich’s actions. I was more than anxious that we should not lose sight of him for an instant, and that I should be kept fully informed of his every action.

So it proved in the event, and once again the Hun’s trickiness brought his carefully planned scheme to failure.
Chapter Thirteen.How Berlin Obtains Information.At last the day—or rather the night—which we had been expecting came. The sun had risen in a cloudless sky, and all day long had poured down a fierce flood of heat and light. London was stifling. Everyone seemed to be the victim of heat lassitude; tempers were decidedly short, and even the most amiable of people seemed suddenly to have developed raw-edged nerves. Added to all this was an uneasy presentiment of danger; “There will be a big raid to-night,” was the thought in the back of everyone’s mind.In order to avoid arousing Mostyn Brown’s suspicions that his house was being watched, we had given up, apparently, all observation on the place during daylight. But not in reality. In a house on the other side of the Square, directly facing that occupied by Mostyn Brown, I had hired a room on the third floor, and from the window, with the help of powerful field-glasses, we could keep the house under the strictest watch. We had not even to enter the Square to reach our tower of vantage, for there was a back entrance from an adjoining street.Towards this eyrie I had bent my steps, and on arriving I found Aubert in a state of suppressed excitement.“Look!” he said, handing me the glasses, and, taking them from him, I levelled them at Mostyn Brown’s room.The ribbon on the parrot’s cage had been changed to yellow!But this was not all. The sun shone full on the window of Mostyn Brown’s house and his room was strongly illuminated. The field-glasses showed us that Mostyn Brown was at home, a most unusual thing in the day-time, and that with him was Blind Heinrich. How Heinrich had got there we could not imagine. Aubert had not seen him enter. They were seated on chairs drawn up to the table, and were poring intently over a book, apparently making memoranda on sheets of paper. As we watched, Madame Gabrielle, habited as a coster girl and carrying a huge basket of flowers, came slowly along the Square, past Mostyn Brown’s house and round past the house in which we were seated.I saw her flutter a signal, and, with her arm resting naturally on the side of the basket, she rapidly tapped out a message with her nimble fingers.“Heinrich has been with Mostyn Brown for the past two hours,” she spelt out. “He came straight from Hereford Road and went into the next house from the back.” Evidently there was some way of communication at the rear of the two houses.I had now no time to waste, and, leaving Aubert and Madame Gabrielle to keep the necessary watch, I hurried off to Whitehall, where I was soon in deep talk with the astute and enterprising chief of the London defences, a keen officer who by sheer merit had forced himself to the very front rank in aircraft service.“Good!” he said, when I had told him my news. “I think we shall give them a surprise to-night. Perhaps you would like to see how we work. Sit down for a bit.” And he turned to his big table, on which stood a telephone.For the next half-hour I watched him, fascinated with his sure grasp of London’s intricate defences, and amazed, though I had thought I knew his capability, at the swiftness and decision with which he issued what to me seemed a veritable jumble of orders. To centre after centre of the aircraft defences he spoke a series of numbers, so bewildering in their speed and complexity that an enemy agent seated in the very room could not have gained a scrap of information. Even to me, familiar as I am with almost every branch of code work, it was a veritable revelation.“I think we are ready for them now,” he said finally, wiping the perspiration from his face, and I could see that even to him the strain had been severe. How well he had done his work all England was to know the next day, though the public never even suspected the magnitude of his task.There was now nothing to do but wait; our traps were set, and it remained to be seen whether the enemy would walk into them. I made my way to my chambers for a few hours’ rest and was soon deeply asleep.At half-past nine Burton, my man, roused me. “The first warning has just come in,” he said.I dressed swiftly and sat down to snatch a hasty supper, knowing well that it might be many hours before I tasted another meal.It was exactly ten o’clock when the report of the first maroon broke the stillness, and London, with one accord, hastened to cover. Ten minutes later the streets were deserted, and a midnight hush reigned supreme. The great city seemed a city of the dead.As we listened a faint, distant boom struck softly on our ears. The strafe had begun!Suddenly, far away to the eastward, a searchlight flickered up into the sky; another and another followed in rapid succession, and soon the entire sky was covered and chequered by dozens of wavering pillars of flame, moving to and fro, methodically searching the heavens as though moved by a single hand. Far above us I caught the soft purr of an aeroplane, evidently one of our own, for the sound was quite different from the deeper and rougher note of the Gothas.Suddenly, with a deafening crash, half a dozen guns barked simultaneously, and, looking out, I saw far away, seemingly caught on a pencil of living light, the ethereal butterfly shape of an enemy aircraft. A second later, in quick succession, came the unmistakable sound of bursting bombs.In the midst of the tumult a single tiny light showed for a moment far up in the sky, just outside the ring of shrapnel that was bursting all round the enemy craft, now hopelessly entangled in the beams of a dozen converging searchlights, and, dive and drop as it would, utterly unable to escape from the zone of effulgent radiance in which it seemed to float.Instantly every gun was silent! We caught the crackle of a machine-gun far up in the air, and a moment later the enemy machine burst into a lurid sheet of flame, and the blazing mass pitched headlong to earth amid a roar of cheering from watchers, who in thousands had braved all possible danger to see the aerial fight heralded by the outburst of machine-gun fire. It was obvious that one of our sentinel aeroplanes, perched far above the raider, had caught sight of him in the searchlights, and, swooping swift as a hawk on his quarry, had sent the Gotha a fiery run to the earth twelve thousand feet below. I learned later that the Gotha had fallen in Essex, the three occupants calcined to cinders in the flood of blazing petrol.That was the extent of London’s excitement for the night. It was not until some hours later that I learnt that no fewer than eight squadrons of Gothas, each consisting of four machines, had started out on their errand of murder for London. Only a single machine got through, and that now lay a heap of ruins. The rest had been split up by gun fire, caught in the beams of endless searchlights, harried to and fro by a vast concentration of British fighting planes swiftly assembled when the warning of the yellow ribbon had become known, and had been relentlessly chased homeward in utter disorder. Their repulse was a triumph brought about by Colonel —’s masterly effort at organisation, when I conveyed to him in Whitehall the news which had reached me through a simple yellow ribbon tied to a grey parrot’s cage!Reports soon began to reach me in swift succession from my subordinates in many quarters. Hereford Road, Harrington Street, and Lembridge Square were being carefully watched. Madame Gabrielle and Aubert, the latter dressed in the guise of a seafarer, were on the alert, with dozens of other reliable agents, ready for anything at a moment’s notice.Suddenly Aubert rang me up on the ’phone. I took up the receiver and spoke to him for a few moments.“Meet me at the corner of Harrington Street at five o’clock,” I said.We met in the grey light of dawn, and I soon learned that, with anything like reasonable good fortune, we had in our hands the opportunity for a great coup. Blind Heinrich had gone to the house soon after the “All clear” had been sounded. He had been followed by Mostyn Brown, again in the uniform of a special constable, and by five other men, one of whom was the little fat man who had previously met Kristensten at Waterloo.Now I had made up my mind that the little fat man was the intermediary by whom the news collected by the other conspirators was conveyed abroad, and it was essential that he should be caught red-handed. Fortune had favoured us. He had been the first to leave the house, had walked to the Queen’s Road Underground Station, and, as we learnt by telephone, had travelled to King’s Cross. Here he was at present, seated in one of the waiting-rooms, evidently intending to travel by an early train.Leaving the necessary instructions with regard to the conspirators still in the house in Harrington Street, I accompanied Aubert to King’s Cross. The little fat man was still there, but just after seven he walked to the booking-office and took a ticket for Peterborough. Just behind him in the queue of passengers were Aubert and myself.When the express pulled out on its fast run to Peterborough—the first stopping-place—Aubert sat in the same carriage as the little fat man, apparently profoundly asleep. I was in the next compartment, ready for anything that might happen.We were not much surprised when at Peterborough the little fat man remained in the train, and so we continued our journey. When tickets were examined, the little man paid excess fare to Newcastle, and my hopes of an important capture rose momentarily higher.Hour after hour the express raced northward, and in the afternoon we came to smoky Newcastle, where we were to be the witnesses of a strangedénouement.The little fat man, closely followed by Aubert and myself, made straight for the docks. Here, in haste, he boarded a steamer, one of a service which sailed regularly between Newcastle and Bergen. He was evidently known, for he was greeted without question by the men about the decks and promptly disappeared below. We followed, with several other passengers, and very soon I sat in the captain’s cabin, swiftly explaining to “the owner” what had happened, and my suspicion of the man who had just come on board with a freedom of movement which suggested that he was one of the crew.Captain Jackson was one of the men who have done so much to make the North Sea service a model of everything that is implied in unswerving courage and loyal devotion to duty. A fine, bluff, grey-bearded skipper of the very best type, he cared not a rap for the peril of mines and submarines which dogged him at every yard of his journeys. All he cared for or respected was the Admiralty orders which gave him his chart through the ever-shifting mine-fields; with those and his crew he was ready to take his ship across to Norway and to defy the Huns to do their worst.His face grew grave and iron-stern as he heard my story, and, loyal Englishman as he was, he instantly fell in with my suggestion for trapping the scoundrel who was bringing disgrace on the good name of all sailors by his infamous traffic with the agents of the enemy.“George Humber is the name he goes by,” said Captain Jackson, referring to the man we had followed from Lembridge Square. “He says he is a Swede and has Swedish papers. Let your French friend go below and help. I’ll see to it.”He called up the chief engineer, Andrew Phail, a dour, hard, bitter Scotchman, who had followed the sea for forty years and cared for nothing on earth but it and his beloved engines. If ever a man loved his machines it was Phail, and if ever a man was loved and trusted by his subordinates it was he. Hard though he was, his crew, with the sure instinct of the sailor, recognised his sterling qualities, and would have followed his lead through the worst storm that ever blew. Indeed, the — was emphatically what is known among sailormen as “a happy ship,” thanks to the captain and chief engineer, and I was not altogether surprised to learn that Humber was the only discordant note among the crew; for some reason the men disliked him, though he did his work well enough.An hour later, having taken our mails on board, we dropped down the Tyne bound for Norway.I learned from Captain Jackson that Humber had signed on some months before, and had made a number of trips across the North Sea. He had been in the habit of travelling to London each time the vessel reached Newcastle, and at length this fact had aroused Captain Jackson’s suspicions, and he had made up his mind that this trip should be Humber’s last. It was, indeed, but the end came in a manner which not even Captain Jackson’s keen wits had anticipated.In the meantime I knew that Aubert, a splendid linguist, who could play many parts, from that of an idler in Paris to a worker in a munition factory, was somewhere below in the engine-room, certainly not very far from Humber, and assuredly very much on the alert.An hour after we left the Tyne mouth I was standing with some of the passengers on deck, watching some winking signals as our convoy appeared out of the misty twilight. Of what the convoy consisted I could not quite discern, but the Captain, before he ascended to his bridge, had said: “Our friends will pick us up presently, and they will see us safely across and look out for submarines.”The night passed without incident, and the next day proved grey and windy. Ever and anon one of our patrolling airships paid us a visit, while three other ships, forming our convoy, stood by, with their deadly guns ever ready to talk in deadly earnest with any submarine that might venture to show her periscope.At ten o’clock that night I was on deck watching a series of strange flashes of light showing in the eastern sky, when a sailor approached, and informed me that the Captain wanted to see me in his cabin. I went at once.“Look here, Mr Sant!” the bluff old seaman exclaimed as soon as I had closed the door, which he locked. “I’ve been rummaging the ship. Does this interest you?” And he brought out from the drawer in his table a bottle of medicine. It had apparently been recently bought from a chemist, for it was wrapped up in the usual paper, which was still quite clean and fresh, and sealed in the usual way. “This was found by your French friend concealed in Humber’s trunk. Your man would be up here, only he is watching the fellow below, and as he is supposed to be on duty his absence might rouse suspicions.”As Captain Jackson ended he handed me the bottle.“It does interest me, indeed,” I said. “If Humber were ill enough to need medicine—and he certainly does not look it—he would hardly have brought this all the way from London without opening it.” And I thought of the bottle wrapped in white paper which, on an earlier visit to London, Humber had received from Blind Heinrich at Waterloo.“I’ll have a look at it, anyhow,” I said.My first precaution was to soften the sealing wax with a match, so that I could unwrap the bottle without tearing the paper, and, if necessary, so replace it that no suspicion that it had been tampered with should be aroused. The bottle might prove useless as a clue. In that case we should have to seek further, and to replace the bottle in Humber’s trunk in such a condition that he must inevitably see that it had been opened would certainly arouse his suspicions and defeat our object.I soon had the paper opened out. The bottle of medicine seemed genuine enough. It bore the label of a well-known West End firm and the name of Mr Humber. I tasted the contents.“Cough mixture” was my comment, and Captain Jackson at once confirmed me. “Humber never had a cough,” he remarked reflectively.“Now for the paper,” I said, and began examining it. It was perfectly blank, and I was experiencing a pang of disappointment when, catching on the paper the reflection of the swinging lamp, I detected in one corner a faint, glistening line. Lemon juice, I was confident.Under appropriate “treatment” a number of neat figures arranged in groups of three sprang into vivid prominence on the inside of the paper wrapping. They ran:123—5—8; 27—32—6; 46—23—11;294—12—3; 18—1—8;and so on.I swiftly copied out the figures for safety, and handed the original paper to Captain Jackson, who, on board his own ship, was, of course, the supreme and unquestioned authority, and I wanted his full approval and support to any action that might be necessary. The figures were meaningless as they stood, but I had not forgotten old Heinrich’s systematic search for that odd volume ofRoyal Love Letters. I had my copy in my bag and fetched it at once.With such an obscure book as the key to the cipher there was no need for any further elaborate precautions, and we hit upon the solution of the difficulty at once. On page 123 the eighth letter on the fifth line was “B;” on page 27 the sixth letter in the thirty-second line was “r”; and in a few minutes I had decoded the word “Brixton.” Going on, I found that the message conveyed the news that Number 24, — Road, Brixton, had been wrecked by one of the bombs dropped in the recent raid; that a man, a woman, and two children had been killed. The spots where the other bombs had fallen were accurately described, and it was stated that they had done no damage beyond blowing holes in the roads and bursting gas and water mains. Every word was accurate.And the key to the whole problem was the mysterious advertisement for a lost trinket in thePetit Parisien. That simple advertisement, so apparently innocent, had announced to Blind Heinrich the enemy’s change of code! And without the book to which it referred no intelligence on earth could have deciphered the disorderly mass of figures which lay before our eyes!“Well, I think we have got them now, Captain,” I said, “and I am sure the Government will be deeply obliged to you for your assistance. But how am I going to get this fellow? If he lands in Norway he will be out of our power.”“Come on deck,” said Captain Jackson, with a laugh. “Don’t make your mind uneasy about that.”I followed him up the companion-way ladder to the deck, now deserted by all save the steersman and the officer on watch.“Come up to the bridge with me,” said the Captain.Although it was so near the period of full moon the night was dark, the sky being covered by a dense mass of heavy clouds. Try as we would, our eyes could not pierce the gloom, and we could see nothing a few yards from the ship. Though we had parted company from the destroyers long before, we were, of course, travelling without lights in view of possible danger, and only the binnacle lamp shed a soft radiance on the ship’s compass. I was soon to learn, however, how closely we were watched.Captain Jackson entered the wheel-house and touched a key. From the masthead above a signal lamp flashed intermittently for a few seconds. Instantly from the southward winked an answering gleam, and Captain Jackson turned to me. “That’s a destroyer,” he said, “and she is coming up full speed.”For the next few minutes signals were exchanged with the racing destroyer which was on our track, and soon I caught sight of the faint glow from her funnels, and then the outline of her low, rakish hull as she came abreast with us. At a signal from Captain Jackson our engines stopped, and soon we were lying motionless while a boat from the destroyer pulled rapidly across the gap which separated the two vessels.A few minutes later a smart naval officer came on board with four men. We were soon seated in the Captain’s cabin, and I rapidly gave him an outline of what had happened. His quick intelligence took in the situation at a glance.“I’ll take your Mr Humber back with me,” he said, “and you and your man can come along.”But we were nearly to lose our man. As the officer and his men entered the engine-room Humber caught sight of them. He started, but instantly recovered himself. As the lieutenant spoke to Phail, Humber watched him closely. I saw Aubert move noiselessly but swiftly behind Humber, evidently ready for a tussle. A moment later Phail beckoned Humber to come to him.Instantly the spy’s hand shot to his jacket pocket, and, as it came out, bringing with it a revolver, Aubert sprang. The next instant the revolver was on the floor and Aubert had Humber in a grip of iron. Ten minutes later, with Humber securely handcuffed, we were on our way to the destroyer, and were soon thrashing our way at top speed for home.There is little more to tell. Humber proved to be a Swede named Holmboë, and we clearly established the fact that he had been for a long time acting as the travelling agent of the Berlin espionage bureau, carrying information to Norway for transmission through the German Legation in Christiania. The conspirators in the house in Harrington Street were all taken into custody, and we soon had all the threads of their activities in our possession, including the key to the mystery of Mr Mostyn Brown, whose connection with various little affairs of espionage was clearly established. Blind Heinrich, too, was at length effectively unmasked, and, with the rest of the group, is now safely under lock and key, with ample leisure to repent of the nefarious business upon which they were engaged.On this occasion, at any rate, the secret message failed to reach Berlin, and I often laugh when I think of the amazement and anxiety that must have been caused in the enemy’s camp at the sudden silence of their emissaries. To-day we can afford to make them a present of the truth!
At last the day—or rather the night—which we had been expecting came. The sun had risen in a cloudless sky, and all day long had poured down a fierce flood of heat and light. London was stifling. Everyone seemed to be the victim of heat lassitude; tempers were decidedly short, and even the most amiable of people seemed suddenly to have developed raw-edged nerves. Added to all this was an uneasy presentiment of danger; “There will be a big raid to-night,” was the thought in the back of everyone’s mind.
In order to avoid arousing Mostyn Brown’s suspicions that his house was being watched, we had given up, apparently, all observation on the place during daylight. But not in reality. In a house on the other side of the Square, directly facing that occupied by Mostyn Brown, I had hired a room on the third floor, and from the window, with the help of powerful field-glasses, we could keep the house under the strictest watch. We had not even to enter the Square to reach our tower of vantage, for there was a back entrance from an adjoining street.
Towards this eyrie I had bent my steps, and on arriving I found Aubert in a state of suppressed excitement.
“Look!” he said, handing me the glasses, and, taking them from him, I levelled them at Mostyn Brown’s room.
The ribbon on the parrot’s cage had been changed to yellow!
But this was not all. The sun shone full on the window of Mostyn Brown’s house and his room was strongly illuminated. The field-glasses showed us that Mostyn Brown was at home, a most unusual thing in the day-time, and that with him was Blind Heinrich. How Heinrich had got there we could not imagine. Aubert had not seen him enter. They were seated on chairs drawn up to the table, and were poring intently over a book, apparently making memoranda on sheets of paper. As we watched, Madame Gabrielle, habited as a coster girl and carrying a huge basket of flowers, came slowly along the Square, past Mostyn Brown’s house and round past the house in which we were seated.
I saw her flutter a signal, and, with her arm resting naturally on the side of the basket, she rapidly tapped out a message with her nimble fingers.
“Heinrich has been with Mostyn Brown for the past two hours,” she spelt out. “He came straight from Hereford Road and went into the next house from the back.” Evidently there was some way of communication at the rear of the two houses.
I had now no time to waste, and, leaving Aubert and Madame Gabrielle to keep the necessary watch, I hurried off to Whitehall, where I was soon in deep talk with the astute and enterprising chief of the London defences, a keen officer who by sheer merit had forced himself to the very front rank in aircraft service.
“Good!” he said, when I had told him my news. “I think we shall give them a surprise to-night. Perhaps you would like to see how we work. Sit down for a bit.” And he turned to his big table, on which stood a telephone.
For the next half-hour I watched him, fascinated with his sure grasp of London’s intricate defences, and amazed, though I had thought I knew his capability, at the swiftness and decision with which he issued what to me seemed a veritable jumble of orders. To centre after centre of the aircraft defences he spoke a series of numbers, so bewildering in their speed and complexity that an enemy agent seated in the very room could not have gained a scrap of information. Even to me, familiar as I am with almost every branch of code work, it was a veritable revelation.
“I think we are ready for them now,” he said finally, wiping the perspiration from his face, and I could see that even to him the strain had been severe. How well he had done his work all England was to know the next day, though the public never even suspected the magnitude of his task.
There was now nothing to do but wait; our traps were set, and it remained to be seen whether the enemy would walk into them. I made my way to my chambers for a few hours’ rest and was soon deeply asleep.
At half-past nine Burton, my man, roused me. “The first warning has just come in,” he said.
I dressed swiftly and sat down to snatch a hasty supper, knowing well that it might be many hours before I tasted another meal.
It was exactly ten o’clock when the report of the first maroon broke the stillness, and London, with one accord, hastened to cover. Ten minutes later the streets were deserted, and a midnight hush reigned supreme. The great city seemed a city of the dead.
As we listened a faint, distant boom struck softly on our ears. The strafe had begun!
Suddenly, far away to the eastward, a searchlight flickered up into the sky; another and another followed in rapid succession, and soon the entire sky was covered and chequered by dozens of wavering pillars of flame, moving to and fro, methodically searching the heavens as though moved by a single hand. Far above us I caught the soft purr of an aeroplane, evidently one of our own, for the sound was quite different from the deeper and rougher note of the Gothas.
Suddenly, with a deafening crash, half a dozen guns barked simultaneously, and, looking out, I saw far away, seemingly caught on a pencil of living light, the ethereal butterfly shape of an enemy aircraft. A second later, in quick succession, came the unmistakable sound of bursting bombs.
In the midst of the tumult a single tiny light showed for a moment far up in the sky, just outside the ring of shrapnel that was bursting all round the enemy craft, now hopelessly entangled in the beams of a dozen converging searchlights, and, dive and drop as it would, utterly unable to escape from the zone of effulgent radiance in which it seemed to float.
Instantly every gun was silent! We caught the crackle of a machine-gun far up in the air, and a moment later the enemy machine burst into a lurid sheet of flame, and the blazing mass pitched headlong to earth amid a roar of cheering from watchers, who in thousands had braved all possible danger to see the aerial fight heralded by the outburst of machine-gun fire. It was obvious that one of our sentinel aeroplanes, perched far above the raider, had caught sight of him in the searchlights, and, swooping swift as a hawk on his quarry, had sent the Gotha a fiery run to the earth twelve thousand feet below. I learned later that the Gotha had fallen in Essex, the three occupants calcined to cinders in the flood of blazing petrol.
That was the extent of London’s excitement for the night. It was not until some hours later that I learnt that no fewer than eight squadrons of Gothas, each consisting of four machines, had started out on their errand of murder for London. Only a single machine got through, and that now lay a heap of ruins. The rest had been split up by gun fire, caught in the beams of endless searchlights, harried to and fro by a vast concentration of British fighting planes swiftly assembled when the warning of the yellow ribbon had become known, and had been relentlessly chased homeward in utter disorder. Their repulse was a triumph brought about by Colonel —’s masterly effort at organisation, when I conveyed to him in Whitehall the news which had reached me through a simple yellow ribbon tied to a grey parrot’s cage!
Reports soon began to reach me in swift succession from my subordinates in many quarters. Hereford Road, Harrington Street, and Lembridge Square were being carefully watched. Madame Gabrielle and Aubert, the latter dressed in the guise of a seafarer, were on the alert, with dozens of other reliable agents, ready for anything at a moment’s notice.
Suddenly Aubert rang me up on the ’phone. I took up the receiver and spoke to him for a few moments.
“Meet me at the corner of Harrington Street at five o’clock,” I said.
We met in the grey light of dawn, and I soon learned that, with anything like reasonable good fortune, we had in our hands the opportunity for a great coup. Blind Heinrich had gone to the house soon after the “All clear” had been sounded. He had been followed by Mostyn Brown, again in the uniform of a special constable, and by five other men, one of whom was the little fat man who had previously met Kristensten at Waterloo.
Now I had made up my mind that the little fat man was the intermediary by whom the news collected by the other conspirators was conveyed abroad, and it was essential that he should be caught red-handed. Fortune had favoured us. He had been the first to leave the house, had walked to the Queen’s Road Underground Station, and, as we learnt by telephone, had travelled to King’s Cross. Here he was at present, seated in one of the waiting-rooms, evidently intending to travel by an early train.
Leaving the necessary instructions with regard to the conspirators still in the house in Harrington Street, I accompanied Aubert to King’s Cross. The little fat man was still there, but just after seven he walked to the booking-office and took a ticket for Peterborough. Just behind him in the queue of passengers were Aubert and myself.
When the express pulled out on its fast run to Peterborough—the first stopping-place—Aubert sat in the same carriage as the little fat man, apparently profoundly asleep. I was in the next compartment, ready for anything that might happen.
We were not much surprised when at Peterborough the little fat man remained in the train, and so we continued our journey. When tickets were examined, the little man paid excess fare to Newcastle, and my hopes of an important capture rose momentarily higher.
Hour after hour the express raced northward, and in the afternoon we came to smoky Newcastle, where we were to be the witnesses of a strangedénouement.
The little fat man, closely followed by Aubert and myself, made straight for the docks. Here, in haste, he boarded a steamer, one of a service which sailed regularly between Newcastle and Bergen. He was evidently known, for he was greeted without question by the men about the decks and promptly disappeared below. We followed, with several other passengers, and very soon I sat in the captain’s cabin, swiftly explaining to “the owner” what had happened, and my suspicion of the man who had just come on board with a freedom of movement which suggested that he was one of the crew.
Captain Jackson was one of the men who have done so much to make the North Sea service a model of everything that is implied in unswerving courage and loyal devotion to duty.

All he cared for or respected was the Admiralty orders which gave him his chart through the ever-shifting mine-fields; with those and his crew he was ready to take his ship across to Norway and to defy the Huns to do their worst.
His face grew grave and iron-stern as he heard my story, and, loyal Englishman as he was, he instantly fell in with my suggestion for trapping the scoundrel who was bringing disgrace on the good name of all sailors by his infamous traffic with the agents of the enemy.
“George Humber is the name he goes by,” said Captain Jackson, referring to the man we had followed from Lembridge Square. “He says he is a Swede and has Swedish papers. Let your French friend go below and help. I’ll see to it.”
He called up the chief engineer, Andrew Phail, a dour, hard, bitter Scotchman, who had followed the sea for forty years and cared for nothing on earth but it and his beloved engines. If ever a man loved his machines it was Phail, and if ever a man was loved and trusted by his subordinates it was he. Hard though he was, his crew, with the sure instinct of the sailor, recognised his sterling qualities, and would have followed his lead through the worst storm that ever blew. Indeed, the — was emphatically what is known among sailormen as “a happy ship,” thanks to the captain and chief engineer, and I was not altogether surprised to learn that Humber was the only discordant note among the crew; for some reason the men disliked him, though he did his work well enough.
An hour later, having taken our mails on board, we dropped down the Tyne bound for Norway.
I learned from Captain Jackson that Humber had signed on some months before, and had made a number of trips across the North Sea. He had been in the habit of travelling to London each time the vessel reached Newcastle, and at length this fact had aroused Captain Jackson’s suspicions, and he had made up his mind that this trip should be Humber’s last. It was, indeed, but the end came in a manner which not even Captain Jackson’s keen wits had anticipated.
In the meantime I knew that Aubert, a splendid linguist, who could play many parts, from that of an idler in Paris to a worker in a munition factory, was somewhere below in the engine-room, certainly not very far from Humber, and assuredly very much on the alert.
An hour after we left the Tyne mouth I was standing with some of the passengers on deck, watching some winking signals as our convoy appeared out of the misty twilight. Of what the convoy consisted I could not quite discern, but the Captain, before he ascended to his bridge, had said: “Our friends will pick us up presently, and they will see us safely across and look out for submarines.”

“Look here, Mr Sant!” the bluff old seaman exclaimed as soon as I had closed the door, which he locked. “I’ve been rummaging the ship.

It had apparently been recently bought from a chemist, for it was wrapped up in the usual paper, which was still quite clean and fresh, and sealed in the usual way. “This was found by your French friend concealed in Humber’s trunk. Your man would be up here, only he is watching the fellow below, and as he is supposed to be on duty his absence might rouse suspicions.”
As Captain Jackson ended he handed me the bottle.
“It does interest me, indeed,” I said. “If Humber were ill enough to need medicine—and he certainly does not look it—he would hardly have brought this all the way from London without opening it.” And I thought of the bottle wrapped in white paper which, on an earlier visit to London, Humber had received from Blind Heinrich at Waterloo.
“I’ll have a look at it, anyhow,” I said.

I soon had the paper opened out. The bottle of medicine seemed genuine enough. It bore the label of a well-known West End firm and the name of Mr Humber. I tasted the contents.
“Cough mixture” was my comment, and Captain Jackson at once confirmed me. “Humber never had a cough,” he remarked reflectively.
“Now for the paper,” I said, and began examining it. It was perfectly blank, and I was experiencing a pang of disappointment when, catching on the paper the reflection of the swinging lamp, I detected in one corner a faint, glistening line. Lemon juice, I was confident.
Under appropriate “treatment” a number of neat figures arranged in groups of three sprang into vivid prominence on the inside of the paper wrapping. They ran:
123—5—8; 27—32—6; 46—23—11;294—12—3; 18—1—8;and so on.
123—5—8; 27—32—6; 46—23—11;294—12—3; 18—1—8;and so on.
I swiftly copied out the figures for safety, and handed the original paper to Captain Jackson, who, on board his own ship, was, of course, the supreme and unquestioned authority, and I wanted his full approval and support to any action that might be necessary. The figures were meaningless as they stood, but I had not forgotten old Heinrich’s systematic search for that odd volume ofRoyal Love Letters. I had my copy in my bag and fetched it at once.

The spots where the other bombs had fallen were accurately described, and it was stated that they had done no damage beyond blowing holes in the roads and bursting gas and water mains. Every word was accurate.
And the key to the whole problem was the mysterious advertisement for a lost trinket in thePetit Parisien. That simple advertisement, so apparently innocent, had announced to Blind Heinrich the enemy’s change of code! And without the book to which it referred no intelligence on earth could have deciphered the disorderly mass of figures which lay before our eyes!
“Well, I think we have got them now, Captain,” I said, “and I am sure the Government will be deeply obliged to you for your assistance. But how am I going to get this fellow? If he lands in Norway he will be out of our power.”
“Come on deck,” said Captain Jackson, with a laugh. “Don’t make your mind uneasy about that.”
I followed him up the companion-way ladder to the deck, now deserted by all save the steersman and the officer on watch.
“Come up to the bridge with me,” said the Captain.
Although it was so near the period of full moon the night was dark, the sky being covered by a dense mass of heavy clouds. Try as we would, our eyes could not pierce the gloom, and we could see nothing a few yards from the ship. Though we had parted company from the destroyers long before, we were, of course, travelling without lights in view of possible danger, and only the binnacle lamp shed a soft radiance on the ship’s compass. I was soon to learn, however, how closely we were watched.
Captain Jackson entered the wheel-house and touched a key. From the masthead above a signal lamp flashed intermittently for a few seconds. Instantly from the southward winked an answering gleam, and Captain Jackson turned to me. “That’s a destroyer,” he said, “and she is coming up full speed.”
For the next few minutes signals were exchanged with the racing destroyer which was on our track, and soon I caught sight of the faint glow from her funnels, and then the outline of her low, rakish hull as she came abreast with us. At a signal from Captain Jackson our engines stopped, and soon we were lying motionless while a boat from the destroyer pulled rapidly across the gap which separated the two vessels.
A few minutes later a smart naval officer came on board with four men. We were soon seated in the Captain’s cabin, and I rapidly gave him an outline of what had happened. His quick intelligence took in the situation at a glance.
“I’ll take your Mr Humber back with me,” he said, “and you and your man can come along.”
But we were nearly to lose our man. As the officer and his men entered the engine-room Humber caught sight of them. He started, but instantly recovered himself. As the lieutenant spoke to Phail, Humber watched him closely. I saw Aubert move noiselessly but swiftly behind Humber, evidently ready for a tussle. A moment later Phail beckoned Humber to come to him.
Instantly the spy’s hand shot to his jacket pocket, and, as it came out, bringing with it a revolver, Aubert sprang. The next instant the revolver was on the floor and Aubert had Humber in a grip of iron. Ten minutes later, with Humber securely handcuffed, we were on our way to the destroyer, and were soon thrashing our way at top speed for home.

Chapter Fourteen.The Great Submarine Plot.To be a success as a secret agent a wide knowledge of European hotels is an absolute necessity.You must, indeed, be familiar with the best hotel in every city of any importance, and scarcely less important is the personal acquaintance of the manager; for without his help you will inevitably find in your path a thousand difficulties, small and great, which, with his friendly assistance, melt almost insensibly away. Duty and inclination alike have led me to make a special study of hotel life, and I think I may say, without undue egotism, that there are fewmaîtres d’hôtelin Europe with whom I am not on terms of acquaintance, and even in many cases warm friendship.I was especially fortunate in this respect in the situation in which I found myself one sunny morning in June, 1917. As the clock struck ten I strolled out of a big hotel, which I will call the Waldesruhe, in Lucerne, and wandered along the shady avenue beside the lake in the direction of the Schwanen-Platz.Luigi Battini, the manager of the Waldesruhe, was one of my closest personal friends, and I should have stayed at the Waldesruhe at any time I was in Lucerne quite apart from the particular business which had brought me there on this occasion. Luigi was one of those marvellously efficient human machines which appear almost to reach omniscience in everything connected, even remotely, with his profession. He would give his guests, off hand and without the slightest hesitation, minutely detailed directions for the most complicated of journeys without opening a time-table, and invariably his information was correct to the smallest particular. He knew at what stations every dining-car was put on every train within a radius of hundreds of miles, and he impressed upon you, in the far-off pre-war days, to remember that the train left Weis for Passau twenty minutes earlier this month than the hour mentioned in the time-table.His memory, especially for faces, was prodigious. Indeed, it was to this that I owed the beginnings of our friendship. Years before Luigi had been a waiter at the great buffet at Liverpool where passengers from the incoming American boats were in the habit of snatching a hasty meal before joining the train for London. I had arrived in England from New York cold and hungry, and, owing to some delay about my baggage, was unable to get to the restaurant until just before the London express was due to start.I had not realised how long I had been delayed, and had just taken my first mouthful of the soup which Luigi had brought me when the bell heralding the immediate departure of the train rang loudly. With a muttered ejaculation of annoyance I hastily threw down on the table the price of my abandoned meal and rushed out, jumped into the train, and a moment later was speeding Londonwards, still cold and hungry and in the very worst of tempers.Of course I promptly forgot the incident, and it was not until a year later that I was forcibly reminded of it. I had again arrived in Liverpool from New York and hurried to the same restaurant for a meal. By some queer chance I made for a table at which Luigi was still the waiter. I should not have known him, but he recollected me and our previous meeting.With a profound bow and a smiling flash of his exquisite teeth, Luigi said quizzically: “Good evening, monsieur. Has monsieur returned for his dinner?”I looked at him in blank astonishment for a moment, then burst into a roar of laughter, as I remembered both him and the long-forgotten incident of a year before. The ice was effectually broken between us, and when I left for London I felt I had made a friend of the smiling Italian. But it was years before I discovered how deep and loyal a mutual regard had sprung out of a trifling incident. But the best friendships not infrequently owe their origin to some such triviality.Time had slipped by since then, and Luigi had climbed the ladder until the humble waiter was a power in the great cosmopolitan world of the hotel. But to me, at any rate, he was the Luigi of old; to others he might be merely the official head of a perfectly appointed hotel, where arrangements seemed to go by clockwork and no one ever heard of such a thing as failure. Always in a frock-coat, whatever the season, whatever the hour of the day; always wearing the diamond pin given him by a travelling monarch; always alert though never obtrusive; known to all his guests, but familiar with hardly any—such was Luigi Battini. And he was one of Hecq’s “friends.”I had gone to Lucerne on purpose to learn something from his lips which he would not risk in the post, and what he had told me half an hour earlier had set me thinking deeply. It entirely confirmed certain information I had been able to gain in London and Lisbon.After a long and meditative walk, I seated myself on theterrasseof a café overlooking the lovely Lake of Lucerne, and, with abockbefore me, wrote out a telegram as follows:“Arthon, Paris.—Returning London fourteenth.—Casentino.”Having finished mybock, I strolled along to the chief telegraph office near the station and dispatched the message. To the uninitiated it conveyed no other meaning than appeared on the surface, but its receipt at the address for which it was destined set various elements of machinery in motion.On the evening of the fourteenth there stepped from the hotel omnibus—a smartly dressed young Frenchwoman, carrying a little sable Pomeranian dog and followed by a porter with her luggage.Luigi met her in the hall, and, with his heels clicked together in his usual attitude of welcome, received her with an exquisite bow. She engaged a room, signed the visitors’ book in the usual way, and then allowed Battini to conduct her up by the lift. As she passed me our eyes met, but without the slightest sign of recognition. Even though the newly arrived guest was none other than my smartest assistant, Madame Gabrielle Soyez.Next day, in consequence of a note I sent her, we met in one of the sitting-rooms in the further, and at the present moment unoccupied—wing of the hotel. She then told me that her own sitting-room was next to one occupied by a Swedish engineer named Oscar Engström, whom I had watched in Lisbon a month before and who was now in Switzerland engaged on some mysterious business which we had not been able to fathom. We strongly suspected, however, from various bits of evidence that had reached us, that the man was in the pay of Germany at the moment, even if he were not one of the regular German agents.When I entered, Madame Gabrielle, smartly attired in a tailor-made gown of navy-blue cloth and a very bewitching hat, was standing at the window, with her pet dog beneath her arm, chatting to the immaculate Luigi, gazing the while on the blue waters of the lake.I found myself reflecting how typically French she was in every detail—dainty in face and figure, immaculately dressed, and possessing that indefinably vivacious great charm which seems to be the monopoly of the cultured Frenchwoman. She could throw it aside when she chose, such was her wonderful versatility, and assume a mask of dullness and stupidity sufficient to ensure that no one meeting her would give her a second glance. It was a valuable accomplishment, and more than once had carried her safely through a difficult and dangerous situation.To-day, among friends, she was her own sunny self. “Ah, Monsieur Gerald,” she cried, springing forward to greet me, “our friend Luigi has been telling me some very strange things—eh?”“I have told Madame pretty well all I know,” said the suave Italian, in excellent English; “but it is not much. Engström has engaged a room for a lady friend—a Madame Bohman.”“Swedish also?” I queried, with a smile. “When does our friend expect Mr Thornton, as he calls himself?”“He is expected any moment,” replied Luigi; “he has retained his room ever since he left for London.”“Good!” I said. And we all three sat down and plunged into an intricate discussion of every detail concerning the suspects and our plan of campaign.My instructions to Luigi were to keep a constant watch upon the comings and goings of the Swedish engineer and his lady friend, while to Madame Gabrielle fell the task of endeavouring to scrape acquaintance with the latter on her arrival, in order to try to gain from some casual remark—for we could expect nothing more—a hint of what was in progress.Engström’s lady friend, Madame Bohman, arrived in due course, and, though she was quite unaware of it, we scrutinised her closely before we gave her a chance of seeing us. I saw at once that she was a complete stranger to me. Madame Gabrielle did not know her, and Luigi, with his faultless memory for faces, declared positively that she had never entered any hotel at which he had been engaged.“A new hand, in all probability,” I thought, “but none the less dangerous on that ground if she knows her business.” Madame Bohman was a tall, handsome, fair-haired woman of decidedly distinguished appearance, and, from the scraps of her conversation which we overheard, evidently well educated and well connected. She had the blue eyes and fair hair of the typical Swede, but blue eyes and fair hair are not exactly unknown in Germany, and, though there was no ostensible reason for it, I found myself wondering whether she was exactly what she professed to be. But the German spy bureau works with any tools that come handy, and, even though Madame Bohman were the pure-blooded Swede she professed to be, there was still no reason why she should not be an enemy agent as well. More than one Swedish “neutral” has been detected in that category and paid the penalty!
To be a success as a secret agent a wide knowledge of European hotels is an absolute necessity.
You must, indeed, be familiar with the best hotel in every city of any importance, and scarcely less important is the personal acquaintance of the manager; for without his help you will inevitably find in your path a thousand difficulties, small and great, which, with his friendly assistance, melt almost insensibly away. Duty and inclination alike have led me to make a special study of hotel life, and I think I may say, without undue egotism, that there are fewmaîtres d’hôtelin Europe with whom I am not on terms of acquaintance, and even in many cases warm friendship.
I was especially fortunate in this respect in the situation in which I found myself one sunny morning in June, 1917. As the clock struck ten I strolled out of a big hotel, which I will call the Waldesruhe, in Lucerne, and wandered along the shady avenue beside the lake in the direction of the Schwanen-Platz.
Luigi Battini, the manager of the Waldesruhe, was one of my closest personal friends, and I should have stayed at the Waldesruhe at any time I was in Lucerne quite apart from the particular business which had brought me there on this occasion. Luigi was one of those marvellously efficient human machines which appear almost to reach omniscience in everything connected, even remotely, with his profession.

He knew at what stations every dining-car was put on every train within a radius of hundreds of miles, and he impressed upon you, in the far-off pre-war days, to remember that the train left Weis for Passau twenty minutes earlier this month than the hour mentioned in the time-table.
His memory, especially for faces, was prodigious. Indeed, it was to this that I owed the beginnings of our friendship. Years before Luigi had been a waiter at the great buffet at Liverpool where passengers from the incoming American boats were in the habit of snatching a hasty meal before joining the train for London.

When I entered, Madame Gabrielle, smartly attired in a tailor-made gown of navy-blue cloth and a very bewitching hat, was standing at the window, with her pet dog beneath her arm, chatting to the immaculate Luigi, gazing the while on the blue waters of the lake.
I found myself reflecting how typically French she was in every detail—dainty in face and figure, immaculately dressed, and possessing that indefinably vivacious great charm which seems to be the monopoly of the cultured Frenchwoman. She could throw it aside when she chose, such was her wonderful versatility, and assume a mask of dullness and stupidity sufficient to ensure that no one meeting her would give her a second glance. It was a valuable accomplishment, and more than once had carried her safely through a difficult and dangerous situation.
To-day, among friends, she was her own sunny self. “Ah, Monsieur Gerald,” she cried, springing forward to greet me, “our friend Luigi has been telling me some very strange things—eh?”
“I have told Madame pretty well all I know,” said the suave Italian, in excellent English; “but it is not much. Engström has engaged a room for a lady friend—a Madame Bohman.”
“Swedish also?” I queried, with a smile. “When does our friend expect Mr Thornton, as he calls himself?”
“He is expected any moment,” replied Luigi; “he has retained his room ever since he left for London.”
“Good!” I said. And we all three sat down and plunged into an intricate discussion of every detail concerning the suspects and our plan of campaign.
My instructions to Luigi were to keep a constant watch upon the comings and goings of the Swedish engineer and his lady friend, while to Madame Gabrielle fell the task of endeavouring to scrape acquaintance with the latter on her arrival, in order to try to gain from some casual remark—for we could expect nothing more—a hint of what was in progress.
Engström’s lady friend, Madame Bohman, arrived in due course, and, though she was quite unaware of it, we scrutinised her closely before we gave her a chance of seeing us. I saw at once that she was a complete stranger to me. Madame Gabrielle did not know her, and Luigi, with his faultless memory for faces, declared positively that she had never entered any hotel at which he had been engaged.
“A new hand, in all probability,” I thought, “but none the less dangerous on that ground if she knows her business.” Madame Bohman was a tall, handsome, fair-haired woman of decidedly distinguished appearance, and, from the scraps of her conversation which we overheard, evidently well educated and well connected. She had the blue eyes and fair hair of the typical Swede, but blue eyes and fair hair are not exactly unknown in Germany, and, though there was no ostensible reason for it, I found myself wondering whether she was exactly what she professed to be. But the German spy bureau works with any tools that come handy, and, even though Madame Bohman were the pure-blooded Swede she professed to be, there was still no reason why she should not be an enemy agent as well. More than one Swedish “neutral” has been detected in that category and paid the penalty!
Chapter Fifteen.The Real Mr Engström.Three days after Madame Bohman’s arrival, a special messenger brought me from Hecq in Paris three reports which, when I had read them, reduced me to a condition of blank despair.The first was from the French Consul-General at Stockholm, who had been instructed to make the closest possible inquiry into thebona fidesof the shipbuilding and engineering firm of Engström and Linner, of Malmö. His report stated that he had paid a visit to Malmö, and as the result of his investigations there and elsewhere he had not the least doubt that they were a first-class firm, and it was a fact of considerable interest that they were employed by the Swedish Government upon several important contracts. No reason whatever could be suggested for doubting their sterling integrity, and the partners had never shown the slightest trace of pro-German bias, either as a firm or individually. This seemed a complete check to our suspicions.The second report was from Aubert, whom I had left in Lisbon. Dated from the Palace Hotel, it read:“I have kept constant observation upon the individual, Mr Thornton, but, with the exception of the fact that he is acquainted with Halbmayr, of the Königgrätzer-strasse—which, after all, may be quite innocent—I see no reason to suspect him of hostile intent. He has telegraphed several times to Lucerne, addressing his messages to the name of Syberg at theposte restante. You could probably secure sight of one of these; I cannot at this end. He was visited a fortnight ago by a Swedish lady named Bohman. The latter may be a travelling agent of the enemy, but somehow, after a close vigilance, I feel doubtful. When Thornton leaves I shall advise you. It will be best for Garcia to follow, as they have not met, and he is here for that purpose.”The third report was from a certain very alert English business man named Charles Johnson-Meads, who had offices in Fenchurch Street, London. It was Johnson-Meads who, by a curious statement he made to me one evening, in my rooms in Curzon Street, London, had first aroused my suspicions that a deep plot, in which Engström and Thornton were somehow implicated, was on foot.Johnson-Meads’ report read:“I have strained every effort to learn more of these people and their mysterious movements in London. Contrary to my belief, I have now established the fact that Engström is, after all, the well-known Swedish engineer, and not the fraud I believed him to be.”This, of course, appeared to be tolerably conclusive, and I was inclined to throw up the whole business at once and return to Paris, where other work urgently awaited my attention. It was clear enough from the report of the French Consul-General at Stockholm that Engström and Linner would not lend their name to any shady proceedings, while Johnson-Meads’ apparent certainty that Engström was really what he professed to be seemed to cut away the principal basis of suspicion.Half an hour later I met Madame Gabrielle and Luigi in the same private room and showed them the three reports, which were as disappointing to them as they were to me. Of Madame Bohman, Gabrielle had failed to discover anything which could give reasonable grounds for suspicion. According to her own statement—for the resourceful Madame Gabrielle had speedily scraped up an hotel acquaintance with her—Madame Bohman and Engström were old friends, having known each other for years in Stockholm. Moreover, it was evident that Madame Bohman at least knew Stockholm well, for Madame Gabrielle was intimately acquainted with that city, and had no difficulty, by means of apparently artless conversation, in testing the accuracy of Madame Bohman’s knowledge. To all intents and purposes we seemed to be on a wild-goose chase, and I expressed this view.“There is nothing in it,” was my verdict. “I think the best thing we can do is to give up wasting our time and get back to Paris at once. You know there is the Morny affair waiting for me, and Hecq is anxious I should take it in hand without delay.”“The Morny affair” was one of those queer financial scandals which have been so rife in Paris during the war. A Frenchman, hitherto of unblemished reputation as a patriot, had suddenly come under suspicion of trafficking with the enemy. Questions and rumours had been flying thickly in the Paris Press, as well as in the Chamber, and it was urgently important that the unfortunate Mr Morny—for I, at least, believed he was being slandered by a group of business rivals and political enemies—should be cleared once and for all of suspicions which were rapidly reducing him to a state of complete prostration. How, later, I succeeded in completely vindicating his character, I hope to tell at some future time—at present a full disclosure of the facts might do untold harm.But Madame Gabrielle, her feminine intuition busily at work, was not to be easily put off. She strongly dissented from my view.“Yesterday,” she said, “during Madame Bohman’s absence with Engström at Brunner, I took Luigi’s master-key, and, entering her room, opened her dressing-case and thoroughly searched her papers. It is true I found nothing of interest, save that there were letters from certain friends in London, the addresses of which I have copied. And I found this!”“This” was a blank sheet of notepaper, which she produced, bearing the heading of the Palace Hotel at Lisbon.“You see,” she said, “it has been very carefully preserved, for it was enclosed in these two envelopes. I wonder why?”I took the blank paper from her and examined it carefully. I found it to be the ordinary hotel notepaper, exactly similar to that which I myself had used in the hotel writing-room, during my recent visit to the Portuguese capital.“Well,” I said, “I don’t see how that proves, or even suggests, anything. We know perfectly well that Madame Bohman has been to Lisbon—she herself makes no secret whatever of the fact, and she may very well have brought away by accident a sheet of the hotel notepaper and a couple of envelopes. It is true she seems friendly with both men, and there is undoubtedly some suspicion. But is it sufficient to justify action on our part, or even to give us good reason for staying here and devoting to a very trivial matter valuable time which at the moment we might be spending to much greater advantage in Paris?”Luigi raised his dark eyebrows and shrugged his shoulders. It was obvious that he was entirely of my way of thinking, and, though he was willing to do anything to help me and to put a spoke in the wheel of the Hun plotters—for, like all patriotic Italians, he cherished the liveliest hatred for the Austro-Germans—he was no fonder than I am myself of the profitless task of chasing a will-o’-the-wisp. But the merry, go-ahead little Frenchwoman had her suspicions very thoroughly aroused, and I knew well that when this was the case it was not an easy task to allay them.“I do not care,mon cherGerald! There is evil work in progress, somewhere; I am confident. Why should Thornton be acquainted or have anything to do with our arch-enemy, Ernst Halbmayr? Remember how cleverly he escaped you six months ago in Rotterdam!”“But we trapped the woman,” I rejoined grimly. “And there was a firing party at Versailles.”“And there is somebody to be trapped here also,” persisted Madame Gabrielle. “You will surely not give up yet?”While we were still discussing the matter a page-boy brought a telegram. Luigi took it from the lad and, dismissing him, handed the message to me. It was from Aubert in Lisbon, and it conveyed the significant news that this man Thornton had left for Lucerne, and that Garcia was travelling by the same train. “He has just sent a telegram to Syberg at theposte restante,” the message concluded.After this, of course, there could be no question of our abandoning our task. There was evidently something afoot, and just as evidently Lucerne was likely to be the scene of some lively incidents.Luigi did not lose a second. He rang the bell, and immediately another page-boy appeared.“Go at once to theposte restante,” he said, “and ask for a telegram for Syberg. They know you come from me, so there will be no need of a letter. Don’t forget the name—S-y-b-e-r-g. And make haste.” The boy disappeared instantly, and for a quarter of an hour we waited in feverish impatience for his return. When he came back he brought with him the message we wanted. Opening it, I read in French, as follows:To Syberg, Poste Restante, Lucerne.“Received good news from London. Meads” (the man in London whose suspicions had been aroused) “is now with us, so business can proceed. Leaving for Lucerne to-night. Shall see T. in Paris to arrange further details and transit of machinery. Thyra” (the Christian name of Madame Bohman) “will meet E.H.” (was this Ernst Halbmayr?) “at Geneva on the 15th.”This message was unsigned, but it confirmed the impression given us by Aubert’s wire that events were on foot, and at once the three of us plunged with renewed energy into our plan of campaign.“There can be no doubt,” I said, “that ‘E.H.’ refers to Halbmayr, and probably he is directing the whole of the intricate affair.”“Very likely,” said Luigi dryly, “but I do not see that we have much more light on what direction against the British the conspirators, if they really are German agents, intend to work.”“True, but that is just what we have to find out,” I replied. “From what Johnson-Meads states, the plot in some way relates to the British submarines. At present I am just as much in the dark as you are. If Halbmayr is directing operations you may depend upon it that some really serious coup is intended, for Halbmayr never troubles his head about the small affairs. Don’t forget that next to Steinhauer he is the man the Königgrätzer-strasse puts most implicit faith in.”Events were now moving rapidly. I waited with anxiety for the arrival of the man Thornton, whom I had never seen, for I was particularly anxious to have a look at him. I suspected very strongly that he was one of the German Secret Service men masquerading under an assumed name, and I was therefore particularly anxious for an opportunity of identifying him. I argued with myself that if he was mixed up with anything big enough to call for the co-operation of Halbmayr he must be one of the “big” men himself, and it was quite possible I might be able to identify him, for personally or through photographs I was well acquainted with most of the leaders of German espionage work.Thornton at length reached the Waldesruhe, where he was greeted by the urbane Luigi with all the evidence of distinguished consideration which made the suave Italian so popular with his many patrons. Thornton would have passed for an Englishman anywhere, both in looks and language. He was perfectly dressed in clothes unmistakably British in cut, and spoke the language to perfection. This, however, was hardly surprising, for, as we learned afterwards, he had lived in London ever since he was fourteen. He had, however, been brought up in circles which were virulently anti-British, and had absorbed to the fullest extent that poisonous hatred of everything English which so frequently displays itself in the Hun who has made England his home of convenience.He little suspected that the smiling Luigi, who so assiduously attended to his comforts, was one of the secret agents of the Allies; that another, in the person of myself, saw his arrival, or that in the turret of the great hotel there was a small secret room containing a powerful wireless set, which I sometimes operated myself.I had to be very careful not to be seen by Thornton, for it was quite possible, if my suspicions were well founded, that he might know me. And it was well that I did, for I recognised him instantly as Emil Brahe, a German agent of whom we had lost sight for some time. He had formerly been engaged on the Continent and was well known to our men, though of late years he seemed to have dropped out of active work, and we had lost sight of him altogether. I realised now that we had been cleverly tricked: we had believed him to belong to the Berlin branch, while all the time he was living quietly in England, where he did no “business” whatever, and was thus never suspected even by the astute men of the Special Branch.We had relied much on Madame Gabrielle’s powers to extract information from Madame Bohman, with whom she was already on excellent terms. The pair often sat chatting in the lounge, smoking each other’s cigarettes, and I knew the fair Gabrielle was keenly on the alert for any slip by which Madame Bohman might “give herself away.” The Swedish woman, however, was far too clever and would betray nothing.Shadowing Thornton, or Brahe, to give him his right name, was Manuel Garcia, a capable ex-detective of the Lisbon police, who was now an agent of the Central Bureau of Counter-Espionage in Paris.That telegrams were constantly passing between the Swedish engineer and some people in Lyons and Marseilles I knew, and, indeed, I was able to secure copies of some of them. In this way I discovered that these Swedes were on very friendly terms with a banker named Heurteau, who had carried on business in Paris before the war, had afterwards escaped to Zurich, and had long been suspected of being one of the paymasters of the spy bureau in Berlin.On the morning of the thirteenth, in consequence of what Madame Gabrielle had told me, I took train to Geneva, where I put up at the National. Manuel Garcia followed by the next train, and early next morning I received a telephone message from Madame Gabrielle telling me that Madame Bohman had left the Waldesruhe and was due at Geneva at four o’clock that afternoon.As a result of this message Garcia and I watched the incoming train, and my assistant followed Madame Bohman in a taxi to a small hotel in the Quai de Mont Blanc. An hour later Garcia himself took a cab to the hotel so as to watch for the arrival of Halbmayr, the real antagonist with whom our duel was being fought out.Halbmayr, a short, stout, bald-headed man, with perfect manners and the air of abon viveur, kept his appointment punctually, arriving from Bâle the next day about noon. As he knew me well, I was compelled to remain in hiding, but from my window I was able, with a pair of good field-glasses, to watch Madame Bohman and the German walking together on the Promenade du Lac, evidently engaged in the closest conversation. Garcia, of course, was not far away.The pair remained together for an hour and a half, and I noticed with amusement that the wily Halbmayr took particular care to select a seat which stood quite in the open, with no shelter of any kind at hand behind which an eavesdropper might lurk. Garcia was thus, of course, effectually kept at a distance, and had no opportunity of gleaning anything from our enemies’ conversation.Apparently the two, in the course of their earnest conversation, arrived at some definite agreement, for when they at length rose and parted, Halbmayr returned direct to the station, where he had left his luggage in the cloak-room, while the Swedish woman went back to her hotel, leaving for Lucerne an hour later.By the next train I also travelled with Garcia to Lucerne. Immediately on our arrival we all had a consultation, and we were deep in talk when I received a startling message from Hecq in Paris. It had been sent to him by Johnson-Meads, who had promised to communicate with me through Hecq if any further suspicious matter came under his notice. The message read:“Cancel my last message; most urgent I should see you immediately.”Now Johnson-Meads’ last message had reported him as being assured of thebona fidesof Engström. The “cancellation” of that could only mean one thing—that the Engström we knew was a fraud, and that for some sinister purpose he was trading on the good name of a perfectly reputable firm of engineers in Sweden.An hour later I was on my way to London.I arrived there without incident, and for an hour sat with Mr Johnson-Meads in his office in Fenchurch Street.“I am afraid you will think me criminally careless, Mr Sant,” he said, “in the matter of my assurance that the man you know as Engström was what he professed to be. But I was deceived by a curious coincidence, and can only offer as an excuse that I have not had your training in solving problems of this kind.“You will remember what I told you when I met you in Curzon Street? Well, that remains true. Where I went wrong was in identifying Engström with the head of the Swedish firm.“It so happened that I have business friends in Malmö, and, after our conversation, being still very suspicious, I wrote to them asking for information about Engström and Linner. I soon received a reply, which was in every way satisfactory, and my correspondent mentioned, quite casually, that Mr Engström was actually in London and was staying at the Hotel Cecil. As I had that very day seen the man we now know as Engström, that seemed to me to clinch the matter, and perhaps foolishly, I dropped all suspicion.“Now for the curious coincidence. A few days ago I was going home by train about six o’clock. The trains, of course, were packed, and I was ‘strap-hanging.’ We had just left King’s Cross when, owing to steam in the tunnel, our train ran with considerable violence into a train which was standing in the tunnel.“The smash was not serious, but the shock was severe, and I was thrown right on top of a gentleman sitting on a seat close by me. A metal dispatch case he was carrying caught my face and, as you will see, cut it very badly. I was stunned for a moment, and when I came round I found the stranger holding me up. He tied a handkerchief round my face, and very kindly helped me out of the train to a hotel, where he got me some brandy, and I soon recovered.“He had to go on, and as we were about to part he handed me his card. I slipped it into my pocket without looking at it, and went home, very much shaken. It was not until two days later that I looked at it. It read:“Engström and Linner, Stockholm. Oscar Engström.“Now, Mr Sant,” he went on, “the Mr Engström who helped me was not the man we both know as Engström! He did not resemble him in the slightest degree. I immediately tried to find Mr Engström, but found to my dismay that he had left the Hotel Cecil and no one knew where he had gone. He was on a holiday tour, and when he tears a few days from business he frequently disappears altogether for a week, in order to get a complete rest from business cares. I have wired Malmö, and all they can tell me is that he will not be back for ten days. Now what can we do?”I thought deeply for a few moments. Obviously I must see the real Mr Engström as soon as possible. But there was no chance of finding him immediately, and in the meantime much might happen. I soon made up my mind.“I shall return to Lucerne at once,” I said, “and go from there to Stockholm in time to meet Mr Engström on his arrival. There is nothing else to be done.”Two days later I was back in Lucerne. “Engström,” his friend Thornton, and Madame Bohman were still there, busy on their plot, whatever it was, and entirely unsuspicious either of the urbane hotel manager or the pretty little Frenchwoman who had apparently developed a lively affection for the handsome Swedish woman.One day I learned from Luigi that, in the course of a couple of hours, Engström had received three telegrams, and had sent a reply to each of them. Of their purport Luigi could gain no knowledge.Now, I was particularly anxious to get a sight of those telegrams, for obviously they might throw a good deal of light on the business on which Engström was engaged. I laid my plans accordingly.That same afternoon, with Luigi’s assistance, I managed to transform myself into a passable imitation of a very unkempt and dirty mechanic, and as soon as the Swedish engineer left the hotel, about half-past five—it was his usual habit to go out to take anapéritif—I took Luigi’s master-key, which unlocked all the doors in the hotel, and crept noiselessly to Engström’s room. I was soon inside, and a few minutes later, with the aid of my own skeleton keys, had opened the big leather travelling trunk, and was hastily examining its contents.A number of telegrams had been hastily thrust into the trunk. I had grasped my prize and was just about to shut and relock the trunk, when I heard a sound behind me, and, turning, found myself face to face with Oscar Engström himself.And not only that, but I was looking straight into the barrel of a very serviceable-looking automatic pistol, held without a tremor in Engström’s very capable hands!
Three days after Madame Bohman’s arrival, a special messenger brought me from Hecq in Paris three reports which, when I had read them, reduced me to a condition of blank despair.
The first was from the French Consul-General at Stockholm, who had been instructed to make the closest possible inquiry into thebona fidesof the shipbuilding and engineering firm of Engström and Linner, of Malmö. His report stated that he had paid a visit to Malmö, and as the result of his investigations there and elsewhere he had not the least doubt that they were a first-class firm, and it was a fact of considerable interest that they were employed by the Swedish Government upon several important contracts. No reason whatever could be suggested for doubting their sterling integrity, and the partners had never shown the slightest trace of pro-German bias, either as a firm or individually. This seemed a complete check to our suspicions.
The second report was from Aubert, whom I had left in Lisbon. Dated from the Palace Hotel, it read:
“I have kept constant observation upon the individual, Mr Thornton, but, with the exception of the fact that he is acquainted with Halbmayr, of the Königgrätzer-strasse—which, after all, may be quite innocent—I see no reason to suspect him of hostile intent. He has telegraphed several times to Lucerne, addressing his messages to the name of Syberg at theposte restante. You could probably secure sight of one of these; I cannot at this end. He was visited a fortnight ago by a Swedish lady named Bohman. The latter may be a travelling agent of the enemy, but somehow, after a close vigilance, I feel doubtful. When Thornton leaves I shall advise you. It will be best for Garcia to follow, as they have not met, and he is here for that purpose.”
The third report was from a certain very alert English business man named Charles Johnson-Meads, who had offices in Fenchurch Street, London. It was Johnson-Meads who, by a curious statement he made to me one evening, in my rooms in Curzon Street, London, had first aroused my suspicions that a deep plot, in which Engström and Thornton were somehow implicated, was on foot.
Johnson-Meads’ report read:
“I have strained every effort to learn more of these people and their mysterious movements in London. Contrary to my belief, I have now established the fact that Engström is, after all, the well-known Swedish engineer, and not the fraud I believed him to be.”
“I have strained every effort to learn more of these people and their mysterious movements in London. Contrary to my belief, I have now established the fact that Engström is, after all, the well-known Swedish engineer, and not the fraud I believed him to be.”
This, of course, appeared to be tolerably conclusive, and I was inclined to throw up the whole business at once and return to Paris, where other work urgently awaited my attention. It was clear enough from the report of the French Consul-General at Stockholm that Engström and Linner would not lend their name to any shady proceedings, while Johnson-Meads’ apparent certainty that Engström was really what he professed to be seemed to cut away the principal basis of suspicion.
Half an hour later I met Madame Gabrielle and Luigi in the same private room and showed them the three reports, which were as disappointing to them as they were to me. Of Madame Bohman, Gabrielle had failed to discover anything which could give reasonable grounds for suspicion. According to her own statement—for the resourceful Madame Gabrielle had speedily scraped up an hotel acquaintance with her—Madame Bohman and Engström were old friends, having known each other for years in Stockholm. Moreover, it was evident that Madame Bohman at least knew Stockholm well, for Madame Gabrielle was intimately acquainted with that city, and had no difficulty, by means of apparently artless conversation, in testing the accuracy of Madame Bohman’s knowledge. To all intents and purposes we seemed to be on a wild-goose chase, and I expressed this view.
“There is nothing in it,” was my verdict. “I think the best thing we can do is to give up wasting our time and get back to Paris at once. You know there is the Morny affair waiting for me, and Hecq is anxious I should take it in hand without delay.”
“The Morny affair” was one of those queer financial scandals which have been so rife in Paris during the war. A Frenchman, hitherto of unblemished reputation as a patriot, had suddenly come under suspicion of trafficking with the enemy. Questions and rumours had been flying thickly in the Paris Press, as well as in the Chamber, and it was urgently important that the unfortunate Mr Morny—for I, at least, believed he was being slandered by a group of business rivals and political enemies—should be cleared once and for all of suspicions which were rapidly reducing him to a state of complete prostration. How, later, I succeeded in completely vindicating his character, I hope to tell at some future time—at present a full disclosure of the facts might do untold harm.
But Madame Gabrielle, her feminine intuition busily at work, was not to be easily put off. She strongly dissented from my view.
“Yesterday,” she said, “during Madame Bohman’s absence with Engström at Brunner, I took Luigi’s master-key, and, entering her room, opened her dressing-case and thoroughly searched her papers. It is true I found nothing of interest, save that there were letters from certain friends in London, the addresses of which I have copied. And I found this!”
“This” was a blank sheet of notepaper, which she produced, bearing the heading of the Palace Hotel at Lisbon.
“You see,” she said, “it has been very carefully preserved, for it was enclosed in these two envelopes. I wonder why?”
I took the blank paper from her and examined it carefully. I found it to be the ordinary hotel notepaper, exactly similar to that which I myself had used in the hotel writing-room, during my recent visit to the Portuguese capital.
“Well,” I said, “I don’t see how that proves, or even suggests, anything. We know perfectly well that Madame Bohman has been to Lisbon—she herself makes no secret whatever of the fact, and she may very well have brought away by accident a sheet of the hotel notepaper and a couple of envelopes. It is true she seems friendly with both men, and there is undoubtedly some suspicion. But is it sufficient to justify action on our part, or even to give us good reason for staying here and devoting to a very trivial matter valuable time which at the moment we might be spending to much greater advantage in Paris?”
Luigi raised his dark eyebrows and shrugged his shoulders. It was obvious that he was entirely of my way of thinking, and, though he was willing to do anything to help me and to put a spoke in the wheel of the Hun plotters—for, like all patriotic Italians, he cherished the liveliest hatred for the Austro-Germans—he was no fonder than I am myself of the profitless task of chasing a will-o’-the-wisp. But the merry, go-ahead little Frenchwoman had her suspicions very thoroughly aroused, and I knew well that when this was the case it was not an easy task to allay them.
“I do not care,mon cherGerald! There is evil work in progress, somewhere; I am confident. Why should Thornton be acquainted or have anything to do with our arch-enemy, Ernst Halbmayr? Remember how cleverly he escaped you six months ago in Rotterdam!”
“But we trapped the woman,” I rejoined grimly. “And there was a firing party at Versailles.”
“And there is somebody to be trapped here also,” persisted Madame Gabrielle. “You will surely not give up yet?”
While we were still discussing the matter a page-boy brought a telegram. Luigi took it from the lad and, dismissing him, handed the message to me. It was from Aubert in Lisbon, and it conveyed the significant news that this man Thornton had left for Lucerne, and that Garcia was travelling by the same train. “He has just sent a telegram to Syberg at theposte restante,” the message concluded.
After this, of course, there could be no question of our abandoning our task. There was evidently something afoot, and just as evidently Lucerne was likely to be the scene of some lively incidents.
Luigi did not lose a second. He rang the bell, and immediately another page-boy appeared.
“Go at once to theposte restante,” he said, “and ask for a telegram for Syberg. They know you come from me, so there will be no need of a letter. Don’t forget the name—S-y-b-e-r-g. And make haste.” The boy disappeared instantly, and for a quarter of an hour we waited in feverish impatience for his return. When he came back he brought with him the message we wanted. Opening it, I read in French, as follows:
To Syberg, Poste Restante, Lucerne.“Received good news from London. Meads” (the man in London whose suspicions had been aroused) “is now with us, so business can proceed. Leaving for Lucerne to-night. Shall see T. in Paris to arrange further details and transit of machinery. Thyra” (the Christian name of Madame Bohman) “will meet E.H.” (was this Ernst Halbmayr?) “at Geneva on the 15th.”
To Syberg, Poste Restante, Lucerne.
“Received good news from London. Meads” (the man in London whose suspicions had been aroused) “is now with us, so business can proceed. Leaving for Lucerne to-night. Shall see T. in Paris to arrange further details and transit of machinery. Thyra” (the Christian name of Madame Bohman) “will meet E.H.” (was this Ernst Halbmayr?) “at Geneva on the 15th.”
This message was unsigned, but it confirmed the impression given us by Aubert’s wire that events were on foot, and at once the three of us plunged with renewed energy into our plan of campaign.
“There can be no doubt,” I said, “that ‘E.H.’ refers to Halbmayr, and probably he is directing the whole of the intricate affair.”
“Very likely,” said Luigi dryly, “but I do not see that we have much more light on what direction against the British the conspirators, if they really are German agents, intend to work.”
“True, but that is just what we have to find out,” I replied. “From what Johnson-Meads states, the plot in some way relates to the British submarines. At present I am just as much in the dark as you are. If Halbmayr is directing operations you may depend upon it that some really serious coup is intended, for Halbmayr never troubles his head about the small affairs. Don’t forget that next to Steinhauer he is the man the Königgrätzer-strasse puts most implicit faith in.”
Events were now moving rapidly. I waited with anxiety for the arrival of the man Thornton, whom I had never seen, for I was particularly anxious to have a look at him. I suspected very strongly that he was one of the German Secret Service men masquerading under an assumed name, and I was therefore particularly anxious for an opportunity of identifying him. I argued with myself that if he was mixed up with anything big enough to call for the co-operation of Halbmayr he must be one of the “big” men himself, and it was quite possible I might be able to identify him, for personally or through photographs I was well acquainted with most of the leaders of German espionage work.
Thornton at length reached the Waldesruhe, where he was greeted by the urbane Luigi with all the evidence of distinguished consideration which made the suave Italian so popular with his many patrons. Thornton would have passed for an Englishman anywhere, both in looks and language. He was perfectly dressed in clothes unmistakably British in cut, and spoke the language to perfection. This, however, was hardly surprising, for, as we learned afterwards, he had lived in London ever since he was fourteen. He had, however, been brought up in circles which were virulently anti-British, and had absorbed to the fullest extent that poisonous hatred of everything English which so frequently displays itself in the Hun who has made England his home of convenience.
He little suspected that the smiling Luigi, who so assiduously attended to his comforts, was one of the secret agents of the Allies; that another, in the person of myself, saw his arrival, or that in the turret of the great hotel there was a small secret room containing a powerful wireless set, which I sometimes operated myself.
I had to be very careful not to be seen by Thornton, for it was quite possible, if my suspicions were well founded, that he might know me. And it was well that I did, for I recognised him instantly as Emil Brahe, a German agent of whom we had lost sight for some time. He had formerly been engaged on the Continent and was well known to our men, though of late years he seemed to have dropped out of active work, and we had lost sight of him altogether. I realised now that we had been cleverly tricked: we had believed him to belong to the Berlin branch, while all the time he was living quietly in England, where he did no “business” whatever, and was thus never suspected even by the astute men of the Special Branch.
We had relied much on Madame Gabrielle’s powers to extract information from Madame Bohman, with whom she was already on excellent terms. The pair often sat chatting in the lounge, smoking each other’s cigarettes, and I knew the fair Gabrielle was keenly on the alert for any slip by which Madame Bohman might “give herself away.” The Swedish woman, however, was far too clever and would betray nothing.
Shadowing Thornton, or Brahe, to give him his right name, was Manuel Garcia, a capable ex-detective of the Lisbon police, who was now an agent of the Central Bureau of Counter-Espionage in Paris.
That telegrams were constantly passing between the Swedish engineer and some people in Lyons and Marseilles I knew, and, indeed, I was able to secure copies of some of them. In this way I discovered that these Swedes were on very friendly terms with a banker named Heurteau, who had carried on business in Paris before the war, had afterwards escaped to Zurich, and had long been suspected of being one of the paymasters of the spy bureau in Berlin.
On the morning of the thirteenth, in consequence of what Madame Gabrielle had told me, I took train to Geneva, where I put up at the National. Manuel Garcia followed by the next train, and early next morning I received a telephone message from Madame Gabrielle telling me that Madame Bohman had left the Waldesruhe and was due at Geneva at four o’clock that afternoon.
As a result of this message Garcia and I watched the incoming train, and my assistant followed Madame Bohman in a taxi to a small hotel in the Quai de Mont Blanc. An hour later Garcia himself took a cab to the hotel so as to watch for the arrival of Halbmayr, the real antagonist with whom our duel was being fought out.
Halbmayr, a short, stout, bald-headed man, with perfect manners and the air of abon viveur, kept his appointment punctually, arriving from Bâle the next day about noon. As he knew me well, I was compelled to remain in hiding, but from my window I was able, with a pair of good field-glasses, to watch Madame Bohman and the German walking together on the Promenade du Lac, evidently engaged in the closest conversation. Garcia, of course, was not far away.
The pair remained together for an hour and a half, and I noticed with amusement that the wily Halbmayr took particular care to select a seat which stood quite in the open, with no shelter of any kind at hand behind which an eavesdropper might lurk. Garcia was thus, of course, effectually kept at a distance, and had no opportunity of gleaning anything from our enemies’ conversation.
Apparently the two, in the course of their earnest conversation, arrived at some definite agreement, for when they at length rose and parted, Halbmayr returned direct to the station, where he had left his luggage in the cloak-room, while the Swedish woman went back to her hotel, leaving for Lucerne an hour later.
By the next train I also travelled with Garcia to Lucerne. Immediately on our arrival we all had a consultation, and we were deep in talk when I received a startling message from Hecq in Paris. It had been sent to him by Johnson-Meads, who had promised to communicate with me through Hecq if any further suspicious matter came under his notice. The message read:
“Cancel my last message; most urgent I should see you immediately.”
Now Johnson-Meads’ last message had reported him as being assured of thebona fidesof Engström. The “cancellation” of that could only mean one thing—that the Engström we knew was a fraud, and that for some sinister purpose he was trading on the good name of a perfectly reputable firm of engineers in Sweden.
An hour later I was on my way to London.
I arrived there without incident, and for an hour sat with Mr Johnson-Meads in his office in Fenchurch Street.
“I am afraid you will think me criminally careless, Mr Sant,” he said, “in the matter of my assurance that the man you know as Engström was what he professed to be. But I was deceived by a curious coincidence, and can only offer as an excuse that I have not had your training in solving problems of this kind.
“You will remember what I told you when I met you in Curzon Street? Well, that remains true. Where I went wrong was in identifying Engström with the head of the Swedish firm.
“It so happened that I have business friends in Malmö, and, after our conversation, being still very suspicious, I wrote to them asking for information about Engström and Linner. I soon received a reply, which was in every way satisfactory, and my correspondent mentioned, quite casually, that Mr Engström was actually in London and was staying at the Hotel Cecil. As I had that very day seen the man we now know as Engström, that seemed to me to clinch the matter, and perhaps foolishly, I dropped all suspicion.
“Now for the curious coincidence. A few days ago I was going home by train about six o’clock. The trains, of course, were packed, and I was ‘strap-hanging.’ We had just left King’s Cross when, owing to steam in the tunnel, our train ran with considerable violence into a train which was standing in the tunnel.
“The smash was not serious, but the shock was severe, and I was thrown right on top of a gentleman sitting on a seat close by me. A metal dispatch case he was carrying caught my face and, as you will see, cut it very badly. I was stunned for a moment, and when I came round I found the stranger holding me up. He tied a handkerchief round my face, and very kindly helped me out of the train to a hotel, where he got me some brandy, and I soon recovered.
“He had to go on, and as we were about to part he handed me his card. I slipped it into my pocket without looking at it, and went home, very much shaken. It was not until two days later that I looked at it. It read:
“Engström and Linner, Stockholm. Oscar Engström.
“Now, Mr Sant,” he went on, “the Mr Engström who helped me was not the man we both know as Engström! He did not resemble him in the slightest degree. I immediately tried to find Mr Engström, but found to my dismay that he had left the Hotel Cecil and no one knew where he had gone. He was on a holiday tour, and when he tears a few days from business he frequently disappears altogether for a week, in order to get a complete rest from business cares. I have wired Malmö, and all they can tell me is that he will not be back for ten days. Now what can we do?”
I thought deeply for a few moments. Obviously I must see the real Mr Engström as soon as possible. But there was no chance of finding him immediately, and in the meantime much might happen. I soon made up my mind.
“I shall return to Lucerne at once,” I said, “and go from there to Stockholm in time to meet Mr Engström on his arrival. There is nothing else to be done.”
Two days later I was back in Lucerne. “Engström,” his friend Thornton, and Madame Bohman were still there, busy on their plot, whatever it was, and entirely unsuspicious either of the urbane hotel manager or the pretty little Frenchwoman who had apparently developed a lively affection for the handsome Swedish woman.

I was soon inside, and a few minutes later, with the aid of my own skeleton keys, had opened the big leather travelling trunk, and was hastily examining its contents.
A number of telegrams had been hastily thrust into the trunk. I had grasped my prize and was just about to shut and relock the trunk, when I heard a sound behind me, and, turning, found myself face to face with Oscar Engström himself.
And not only that, but I was looking straight into the barrel of a very serviceable-looking automatic pistol, held without a tremor in Engström’s very capable hands!
