The young men glanced at each other and accepted the suggestion. He made the acting pilot look up the intrinsic brightness of its sun and measure its apparent brightness from just off Dara. He made him estimate the change in brightness to be expected after so many hours in overdrive, if one broke out to measure.
The first blueskin student pilot ended a Calhoun-determined tour of duty with more respect for Calhoun then he'd had at the beginning. The second was anxious to show up better than the first. Calhoun drilled him in the use of brightness-charts, by which the changes in apparent brightness of stars between overdrive hops could be correlated with angular changes to give a three-dimensional picture of the nearer heavens.
It was a highly necessary art which had not been worked out on Dara, and the prospective astrogators became absorbed in this and other fine points of space-piloting. They'd done enough, in a few trips to Orede, to realize that they needed to know more. Calhoun showed them.
Calhoun did not try to make things easy for them. He was hungry and easily annoyed. It was sound training tactics to be severe, and to phrase all suggestions as commands. He put the four young men in command of the ship in turn, under his direction. He continued to use Weald as a destination, but he set up problems in which the Med Ship came out of overdrive pointing in an unknown direction and with a precessory motion.
He made the third of his students identify Weald in the celestial globe containing hundreds of millions of stars, and get on course in overdrive toward it. The fourth was suddenly required to compute the distance to Weald from such data as he could get from observation, without reference to any records.
By this time the first man was chafing to take a second turn. Calhoun gave each of them a second gruelling lesson. He gave them, in fact, a highly condensed but very sound course in the art of travel in space. His young students took command in four-hour watches, with at least one breakout from overdrive in each watch.
He built up enthusiasm in them. They ignored the discomfort of being hungry—though there had been no reason for them to stint on food on Orede—in growing pride in what they came to know.
When Weald was a first-magnitude star, the four were not highly qualified astrogators, to be sure, but they were vastly better spacemen than at the beginning. Inevitably, their attitude toward Calhoun was respectful. He'd been irritable and right. To the young, the combination is impressive.
Maril had served as passenger only. In theory she was to compare Calhoun's lessons with his practise when alone. But he did nothing on this journey which, teaching considered, was different from the two interstellar journeys Maril had made with him.
She occupied the sleeping cabin during two of the six watches of each ship-day. She operated the food-readier, which was almost completely emptied of its original store of food, it having been confiscated by the government of Dara.That amount of food would make no difference to the planet, but it was wise for everyone on Dara to be equally ill-fed.
On the sixth day out from Dara, the sun of Weald had a magnitude of minus five-tenths. The electron telescope could detect its larger planets, especially a gas-giant fifth-orbit world of high albedo. Calhoun had his four students estimate its distance again, pointing out the difference that could be made in breakout position if the Med Ship were mis-aimed by as much as one second of arc.
"And now," he said briskly, "we'll have coffee. I'm going to graduate you as pilots. Maril, four cups of coffee, please."
Murgatroyd said "Chee?" The Med Ship was badly crowded with six humans and Murgatroyd in a space intended for Calhoun and Murgatroyd alone. The littletormalhad spent most of his time in his cubbyhole, watching with beady eyes as so many people moved about on what had been a spacious ship before.
"No coffee for you, Murgatroyd," said Calhoun. "You didn't do your lessons. This is for the graduating class only."
Murgatroyd came out of his miniature den. He found his little cup and offered it insistently, saying, "Chee! Chee! Chee!"
"No!" said Calhoun firmly. He regarded his class of four young men with their blueskin markings. "Drink it down!" he commanded. "That's the last order I'll give you. You're graduate pilots, now!"
They drank the coffee with a flourish. There was not one who did not admire Calhoun for having made them admire themselves. They were, actually, almost as much better pilots as they believed.
"And now," said Calhoun, "I suppose you'll tell me the truth about those boxes you brought on board. You said theywere rations, but they haven't been opened in six days. I have an idea what they mean, but you tell me."
The four looked uncomfortable. There was a long pause.
"They could be," said Calhoun detachedly, "cultures to be dumped on Weald. Weald is making plans to wipe out Dara. So some fool has decided to get Weald too busy fighting a plague of its own to bother with you. Is that right?"
The young men stirred unhappily. Young men can very easily be made into fanatics. But they have to be kept stirred up. They can't be provided with sound reason for self-respect. On the Med Ship there'd not been a single reference to Weald except as an object toward which the Med Ship was being astrogated. There'd been no reference to blueskins or enemies or threats or anything but space-piloting. The four young men were now fanatical about the proper handling of a ship in emptiness.
"Well, sir," said one of them, unhappily, "that's what we were ordered to do."
"I object," said Calhoun. "It wouldn't work. I just left Weald a little while back, remember. They've been telling themselves that some day Dara would try that. They've made preparations to fight any imaginable contagion you could drop on them. Every so often somebody claims it's happening. It wouldn't work. I object!"
"But—"
"In fact," said Calhoun, "I forbid it. I shall prevent it. You shan't do anything of the kind."
One of the young men, staring at Calhoun, nodded suddenly. His eyes closed. He jerked his head erect and looked bewildered. A second sank heavily into a chair. He said remotely, "Thish sfunny!" and abruptly went to sleep. The third found his knees giving way. He paid elaborate attention to them, stiffening them. But they yielded like rubberand he went slowly down to the floor. The fourth said thickly and reproachfully, "Thought y'were our frien'!"
He collapsed.
Calhoun very soberly tied them hand and foot and laid them out comfortably on the floor. Maril watched, white-faced, her hand to her throat. Murgatroyd looked agitated. He said anxiously, "Chee? Chee?"
"No," said Calhoun. "They'll wake up presently."
Maril said in a tense and desperate whisper, "You're betraying us! You're going to take us to Weald!"
"No," said Calhoun. "We'll only orbit around it. First, though, I want to get rid of those damned packed-up cultures. They're dead, by the way. I killed them with super-sonics a couple of days ago, while a fine argument was going on about distance-measurements by variable Cepheids of known period."
He put the four boxes carefully in the disposal unit. He operated it. The boxes and their contents streamed out to space in the form of metallic and other vapors. Calhoun sat at the control desk.
"I'm a Med Service man," he said detachedly. "I couldn't cooperate in the spread of plagues, anyhow, though a useful epidemic might be another matter. But the important thing right now is not keeping Weald busy with troubles to increase their hatred of Dara. It's getting some food for Dara. And driblets won't help. What's needed is thousands of tons, or tens of thousands." Then he said, "Overdrive coming, Murgatroyd! Hold fast!"
The universe vanished. The customary unpleasant sensations accompanied the change. Murgatroyd burped.
A large part of the firmament was blotted out by the blindingly bright half-disk of Weald, as it shone in the sunshine. It had icecaps at its poles, and there were seas, and the mottled look of land which had that carefully maintained balance of woodland and cultivated areas which was so effective in climate control. The Med Ship floated free, and Calhoun fretfully monitored all the beacon frequencies known to man.
There was relative silence inside the ship. Maril watched Calhoun in a sort of despairing indecision. The four young blueskins still slept, still bound hand and foot upon the control room floor. Murgatroyd regarded them, and Maril, and Calhoun in turn, and his small and furry forehead wrinkled helplessly.
"They can't have landed what I'm looking for!" protested Calhoun as his search had no result. "They can't! It would be too sensible for them to have done it!"
Murgatroyd said "Chee!" in a subdued voice.
"But where the devil did they put them?" demanded Calhoun. "A polar orbit would be ridiculous! They—" Then he grunted in disgust. "Oh! Of course! Now, where's the landing-grid?"
He worked busily for minutes, checking the position of the Wealdian landing-grid, which was mapped in the Sector Directory, against the look of continents and seas on the half-disk so plainly visible outside. He found what he wanted. He put on the ship's solar system drive.
"I wish," he complained to Maril, "I wish I could think straight the first time! And it's so obvious! If you want to put something out in space, and not have it interfere with traffic,in what sort of orbit and at what distance will you put it?"
Maril did not answer.
"Obviously," said Calhoun, "you'll put it as far as possible from the landing-pattern of ships coming in to the spaceport. You'll put it on the opposite side of the planet. And you'll want it to stay out of the way, where anybody can know it is at any time of the day or night without having to calculate anything.
"So you'll put it out in orbit so it will revolve around Weald in exactly one day, neither more nor less, and you'll put it above the equator. And then it will remain quite stationary above one spot on the planet, a hundred and eighty degrees longitude away from the landing-grid and directly over the equator."
He scribbled for a moment.
"Which means forty-two thousand miles high, give or take a few hundred, and—here! And I was hunting for it in a close-in orbit!"
He grumbled to himself. He waited while the solar-system drive pushed the Med Ship a quarter of the way around the bright planet below. The sunset line vanished and the planet's disk became a complete circle. Then Calhoun listened to the monitor earphones again, and grunted once more, and changed course, and presently made a noise indicating satisfaction.
He abandoned instrument control and peered directly out of a port, handling the solar system drive with great care. Murgatroyd said depressedly, "Chee!"
"Stop worrying," commanded Calhoun. "We haven't been challenged, and there is a beacon transmitter at work, just to make sure that nobody bumps into what we're looking for. It's a great help, because we do want to bump, but gently."
Stars swung across the port out of which he looked. Something dark appeared, and then straight lines and exact curvings. Even Maril, despairing and bewildered as she was, caught sight of something vastly larger than the Med Ship, floating in space. She stared. The Med Ship maneuvered very cautiously. She saw another large object. A third. A fourth. There seemed to be dozens of them.
They were spaceships, huge by comparison withAesclipus Twenty. They floated as the Med Ship did. They did not drive. They were not in formation. They were not at even distances from each other. They did not point in the same direction. They swung in emptiness like derelicts.
Calhoun jockeyed his small ship with infinite care. Presently there came the gentlest of impacts and then a clanking sound. The appearance out the vision port became stationary, but still unbelievable. The Med Ship was grappled magnetically to a vast surface of welded metal.
Calhoun relaxed. He opened a wall panel and brought out a vacuum suit. He began briskly to get it on.
"Things moving smoothly," he commented. "We weren't challenged. So it's extremely unlikely that we were spotted. Our friends on the floor ought to begin to come to shortly. And I'm going to find out now whether I'm a hero or in sure-enough trouble!"
Maril said drearily, "I don't know what you've done, except—"
Calhoun blinked at her, in the act of hauling the vacuum suit up his chest and over his shoulders.
"Isn't it self-evident?" he demanded. "I've been giving astrogation lessons to these characters. I certainly didn't do it to help them dump germ-cultures on Weald! I brought them here! Don't you see the point? These are space ships. They're in orbit around Weald. They're not manned and they're not controlled. In fact, they're nothing but sky-riding storage bins!"
He seemed to consider the explanation complete. He wriggled his arms into the sleeves and gloves of the suit. He slung the air tanks over his shoulder and hooked them to the suit.
"I'll be back," he said. "I hope with good news. I've reason to be hopeful, though, because these Wealdians are very practical men. They have things all prepared and tidy. I suspect I'll find these ships with stores of air and fuel, maybe even food, so that if Weald should manage to make a deal for the stuff stored out here in them, they'd only have to bring out crews."
He lifted the space helmet down from its rack and put it on. He tested it, reading the tank air-pressure, power-storage, and other data from the lighted miniature instruments visible through pinholes above his eye-level. He fastened a space rope about himself, speaking through the helmet's opened faceplate.
"If our friends should wake up before I get back," he added, "please restrain them. I'd hate to be marooned."
He went waddling into the airlock with the coil of space rope over one vacuum-suited arm. The inner lock door closed behind him. A little later Maril heard the outer lock open. Then silence.
Murgatroyd whimpered a little. Maril shivered. Calhoun had gone out of the ship to nothingness. He'd said that what he was looking for, and what he'd found, was forty-two thousand miles from Weald. One could imagine falling forty-two thousand miles, where one couldn't imagine falling a light-year.
Calhoun was walking on the steel plates of a gigantic spaceship which floated among dozens of its fellows, all seeming derelicts and seemingly abandoned. He was able to walk on the nearest because of magnetic-soled shoes. Hetrusted his life to them and to a flimsy space rope which trailed after him out the Med Ship's airlock.
Time passed. A clock ticked in that hurried tempo of five ticks to the second which has been the habit of clocks since time immemorial. Very small and trivial noises came from the background tape, preventing utter silence from hanging intolerably in the ship.
Maril found herself listening tensely for something else. One of the four bound blueskins snored, and stirred, and slept again. Murgatroyd gazed about unhappily, and swung down to the control room floor, and then paused for lack of any place to go or anything to do. He sat down and began half-heartedly to lick his whiskers. Maril stirred.
Murgatroyd looked at her hopefully.
"Chee?" he asked shrilly.
She shook her head. It became a habit to act as if Murgatroyd were a human being. "No," she said unsteadily. "Not yet."
More time passed. An unbearably long time. Then there was the faintest of clankings. It repeated. Then, abruptly, there were noises in the airlock. They continued. They were fumbling noises.
The outer airlock door closed. The inner door opened. Dense white fog came out of it. There was motion. Calhoun followed the fog out of the lock. He carried objects which had been weightless, but were suddenly heavy in the ship's gravity-field. There were two spacesuits and a curious assortment of parcels. He spread them out, flipped aside his faceplate, and said briskly, "This stuff is cold! Turn a heater on it, will you, Maril?"
He began to work his way out of his own vacuum-suit.
"Item," he said. "The ships are fuelledandprovisioned. A practical tribe, the Wealdians! The ships are ready to takeoff as soon as they're warmed up inside. A half-degree sun doesn't radiate heat enough to keep a ship warm, when the rest of the cosmos is effectively near zero Kelvin. Here, point the heaters like this."
He adjusted the radiant-heat dispensers. The fog disappeared where their beams played. But the metal spacesuits glistened and steamed, and the steam disappeared within inches. They were so completely and utterly cold that they condensed the air about them as a liquid, which re-evaporated to make fog, which warmed up and disappeared and was immediately replaced.
"Item," said Calhoun again, getting his arms out of the vacuum-suit sleeves. "The controls are pretty nearly standard. Our sleeping friends will be able to astrogate them back to Dara without trouble, provided only that nobody comes out here to bother us before they leave."
He shed the last of the spacesuit, stepping out of its legs.
"And," he finished wryly, "I brought back an emergency supply of ship provisions for everybody concerned, but find that I'm idiot enough to feel that they'll choke me if I eat them while Dara's still starving."
Maril said, "But there isn't any hope for Dara! No real hope!"
He gaped at her.
"What do you think we're here for?"
He set to work to restore his four recent students to consciousness. It was not a difficult task. The dosage mixed in the coffee given them as a graduation ceremony—the ceremony which had consisted solely of drinking coffee and passing out—allowed for waking-up processes. Calhoun took the precaution of disarming them first, but presently four hot-eyed young men glared at him.
"I'm calling," said Calhoun, holding a blaster negligentlyin his hand, "I'm calling for volunteers. There's a famine on Dara. There've been unmanageable crop surpluses on Weald. On Dara, the government grimly rations every ounce of food. On Weald, the government has been buying surplus grain to keep the price up.
"To save storage costs, it's loaded the grain into out-of-date spaceships it once used to stand sentry over Dara to keep it out of space when there was another famine there. Those ships have been put out in orbit, where we're hooked on to one of them.
"It's loaded with half a million bushels of grain. I've brought spacesuits from it, I've turned on the heaters in its interior, and I've set its overdrive unit for a hop to Dara. Now I'm calling for volunteers to take half a million bushels of grain to where it's needed. Do I get any volunteers?"
He got four. Not immediately, because they were ashamed that he'd made it impossible to carry out their original fanatic plan, and now offered something much better to make up for it. They raged. But half a million bushels of grain meant that people who must otherwise die might live.
Ultimately, truculently, first one and then another angrily agreed.
"Good!" said Calhoun. "Now, how many of you dare risk the trip alone? I've got one grain ship warming up. There are plenty of others around us. Every one of you can take a ship and half a million bushels to Dara, if you have the nerve!"
The atmosphere changed. Suddenly they clamored for the task he offered them. They were still acutely uncomfortable. He'd bossed them and taught them until they felt capable and glamorous and proud. Then he'd pinned their ears back. But if they returned to Dara with four enemy ships and unimaginable quantities of food with which to break the famine....
There was work to be done first, of course. Only one ship was so far warming up. Three more had to be entered, in spacesuits, and each had to have its interior warmed so breathable air could exist inside it, and at least part of the stored provisions had to be brought up to reasonable temperature for use on the journey.
Then the overdrive unit had to be inspected and set for the length of journey that a direct overdrive hop to Dara would mean, and Calhoun had to make sure again that each of the four could identify Dara's sun under all circumstances and aim for it with the requisite high precision, both before going into overdrive and after breakout. When all that was accomplished, Calhoun might reasonably hope that they'd arrive. But it wasn't a certainty.
Still, presently his four students shook hands with him, with the fine tolerance of young men intending much greater achievements than their teacher. They wouldn't speak on communicator again, because their messages might be picked up on Weald.
Of course, for this high heroic action to be successful, it had to be performed with the stealth of sneak-thieves.
What seemed a long time passed. The one ship turned slowly upon some unseen axis. It wavered back and forth, seeking a point of aim. A second twisted in its place. A third put on the barest trace of solar system drive to get clear of the rest. The fourth—
One ship vanished. It had gone into overdrive, heading for Dara at many times the speed of light. Another. Two more.
That was all. The remainder of the fleet hung clumsily in emptiness. And Calhoun worriedly went over in his mind the lessons he'd given in such a pathetically small number ofdays. If the four ships reached Dara, their pilots would be heroes. Calhoun had presented them with that estate over their bitter objection. But they would glory in it—if they reached Dara.
Maril looked at him with very strange eyes.
"Now what?" she asked.
"We hang around," said Calhoun, "to see if anybody comes up from Weald to find out what's happened. It's always possible to pick up a sort of signal when a ship goes into overdrive. Usually it doesn't mean a thing. Nobody pays any attention. But if somebody comes out here...."
"What?"
"It'll be regrettable," said Calhoun. He was suddenly very tired. "It'll spoil any chance of our coming back and stealing some more food, like interstellar mice. If they find out what we've done they'll expect us to try it again. They might get set to fight. Or they might simply land the rest of these ships."
"If I'd realized what you were about," said Maril, "I'd have joined in the lessons. I could have piloted a ship."
"You wouldn't have wanted to," said Calhoun. He yawned. "You wouldn't want to be a heroine. No normal girl does."
"Why?"
"Korvan," said Calhoun. He yawned again. "I've asked about him. He's been trying very desperately to deserve well of his fellow blueskins. All he's accomplished is develop a way to starve painlessly. He wouldn't feel comfortable with a girl who'd helped make starving unnecessary. He'd admire you politely, but he'd never marry you. And you know it."
She shook her head, but it was not easy to tell whether she denied the reaction of Korvan, whom Calhoun had never met, or denied that he was more important to her than anything else. The last was what Calhoun plainly implied.
"You don't seem to be trying to be a hero!" she protested.
"I'd enjoy it," admitted Calhoun, "but I have a job to do. It's got to be done. It's more important than being admired."
"You could take another ship back," she told him. "It would be worth more to Dara than the Med Ship is! And then everybody would realize that you'd planned everything."
"Ah," said Calhoun, "but you've no idea how much this ship matters to Dara!"
He seated himself at the controls. He slipped headphones over his ears. He listened. Very, very carefully, he monitored all the wave lengths and wave forms he could discover in use on Weald. There was no mention of the oddity of behavior of shiploads of surplus grain aloft. There was no mention of the ships at all. There was plenty of mention of Dara, and blueskins, and of the vicious political fight now going on to see which political party could promise the most complete protection against blueskins.
After a full hour of it, Calhoun flipped off his receptor and swung the Med Ship to an exact, painstakingly precise aim at the sun around which Dara rolled. He said, "Overdrive coming, Murgatroyd!"
Murgatroyd grabbed. The stars went out and the universe reeled and the Med Ship became a sort of cosmos all its own, into which no signal could come, no danger could enter, and in which there could be no sound except those minute ones made to prevent silence.
Calhoun yawned again.
"Now there's nothing to be done for a day or two," he said wearily, "and I'm beginning to understand why people sleep all they can, on Dara. It's one way not to feel hungry. And one dreams such delicious meals! But looking hungry is a social requirement, on Dara."
Maril said tensely, "You're going back? After they took the ship from you?"
"The job's not finished," he explained. "Not even the famine's ended, and the famine's a second-order effect. If there were no such thing as a blueskin, there'd be no famine. Food could be traded for. We've got to do something to make sure there are no more famines."
She looked at him oddly.
"It would be desirable," she said with irony. "But you can't do it."
"Not today, no," he admitted. Then he said longingly, "I didn't get much sleep on the way here, while running a seminar on astrogation. I think I'll take a nap."
She rose and almost ostentatiously went into the other cabin, to leave him alone. He shrugged. He settled down into the chair which, to let a Med Ship man break the monotony of life in unchanging surroundings, turned into a comfortable sleeping arrangement. He fell instantly asleep.
For very many ship-hours, then, there was no action or activity or happening of any imaginable consequence in the Med Ship. Very, very far away, light-years distant and light-years apart, four shiploads of grain hurtled toward the famine-stricken planet of blueskins. Each great ship had a single semiskilled blueskin for pilot and crew.
Thousands of millions of suns blazed with violence appropriate to their stellar types in a galaxy of which a very small proportion had been explored and colonized by humanity. The human race was now to be counted in quadrillions on scores of hundreds of inhabited worlds, but the tiny Med Ship seemed the least significant of all possible created things.
It could travel between star-systems and even star-clusters, but it was not yet capable of crossing the continent of sunson which the human race arose. And between any two solar systems the journeying of the Med Ship consumed much time. Which would be maddening for someone with no work to do or no resources in himself, or herself.
On the second ship-day Calhoun labored painstakingly and somewhat distastefully at the little biological laboratory. Maril watched him in a sort of brooding silence. Murgatroyd slept much of the time, with his furry tail wrapped meticulously across his nose.
Toward the end of the day Calhoun finished his task. He had a matter of six or seven cubic centimeters of clear liquid as the conclusion of a long process of culturing, and examination by microscope, and again culturing plus final filtration. He looked at a clock and calculated time.
"Better wait until tomorrow," he observed, and put the bit of clear liquid in a temperature-controlled place of safekeeping.
"What is it?" asked Maril. "What's it for?"
"It's part of a job I have on hand," said Calhoun. He considered. "How about some music?"
She looked astonished. But he set up an instrument and fed microtape into it and settled back to listen. Then there was music such as she had never heard before. It was another device to counteract isolation and monotonous between-planet voyages. To keep it from losing its effectiveness, Calhoun rationed himself on music, as on other things.
Any indulgence frequently repeated would become a habit, in the sense that it would give no special pleasure when indulged in, but would make for stress if it were omitted. Calhoun deliberately went for weeks between uses of his recordings, so that music was an event to be looked forward to and cherished.
When he tapered off the stirring symphonies of Kun Geewith tranquilizing, soothing melodies from the Rim School of composers, Maril regarded him with a very peculiar gaze indeed.
"I think I understand now," she said slowly, "why you don't act like other people. Toward me, for example. The way you live gives you what other people have to get in crazy ways—making their work feed their vanity, and justify pride, and make them feel significant. But you can put your whole mind on your work."
He thought it over.
"Med Ship routine is designed to keep one healthy in his mind," he admitted. "It works pretty well. It satisfies all my mental appetites. But there are instincts...."
She waited. He did not finish.
"What do you do about the instincts that work and music and such things can't satisfy?"
Calhoun grinned wryly, "I'm stern with them. I have to be."
He stood up and plainly expected her to go into the other cabin for the night. She went.
It was after breakfast time of the next ship-day when he got out the sample of clear liquid he'd worked so long to produce.
"We'll see how it works," he observed. "Murgatroyd's handy in case of a slip-up. It's perfectly safe so long as he's aboard and there are only the two of us."
She watched as he injected half a cc. under his own skin. Then she shivered a little.
"What will it do?"
"That remains to be seen." He paused a moment. "You and I," he said with some dryness, "make a perfect test for anything. If you catch something from me, it will be infectious indeed!"
She gazed at him utterly without comprehension.
He took his own temperature. He brought out the folios which were his orders, covering each of the planets he should give a standard Medical Service inspection. Weald was there. Dara wasn't. But a Med Service man has much freedom of action, even when only keeping up the routine of normal Med Service. When catching up on badly neglected operations, he necessarily has much more. Calhoun went over the folios.
Two hours later he took his temperature again. He looked pleased. He made an entry in the ship's log. Two hours later yet he found himself drinking thirstily and looked more pleased still.
He made another entry in the log and matter-of-factly drew a small quantity of blood from his own vein and called to Murgatroyd. Murgatroyd submitted amiably to the very trivial operation Calhoun carried out. Calhoun put away the equipment and saw Maril staring at him with a certain look of shock.
"It doesn't hurt him," Calhoun explained. "Right after he's born there's a tiny spot on his flank that has the pain-nerves desensitized. Murgatroyd's all right. That's what he's for!"
"But he's your friend!" said Maril.
Murgatroyd, despite his small size and furriness, had all the human attributes an animal which lives with humans soon acquires. Calhoun looked at him with affection.
"He's my assistant. I don't ask anything of him that I can do myself. But we're both Med Service. And I do things for him that he can't do for himself. For example, I make coffee for him."
Murgatroyd heard the familiar word. He said, "Chee!"
"Very well," agreed Calhoun. "We'll all have some."
He made coffee. Murgatroyd sipped at the cup especially made for his little paws. Once he scratched at the place on his flank which had no pain nerves. It itched. But he wasperfectly content. Murgatroyd would always be contented when he was somewhere near Calhoun.
Another hour went by. Murgatroyd climbed up into Calhoun's lap and with a determined air went to sleep there. Calhoun disturbed him long enough to get an instrument out of his pocket. He listened to Murgatroyd's heartbeat, while Murgatroyd dozed.
"Maril," he said. "Write down something for me. The time, and ninety-six, and one-twenty over ninety-four."
She obeyed, not comprehending. Half an hour later, still not stirring to disturb Murgatroyd, he had her write down another time and sequence of figures, only slightly different from the first. Half an hour later still, a third set. But then he put Murgatroyd down, well satisfied.
He took his own temperature. He nodded.
"Murgatroyd and I have one more chore to do," he told her. "Would you go in the other cabin for a moment?"
Disturbed, she went into the other cabin. Calhoun drew a small sample of blood from the insensitive area on Murgatroyd's flank. Murgatroyd submitted with complete confidence in the man. In ten minutes Calhoun had diluted the sample, added an anticoagulant, shaken it up thoroughly, and filtered it to clarity with all red and white corpuscles removed. Another Med Ship man would have considered that Calhoun had had Murgatroyd prepare a splendid small sample of antibody-containing serum, in case something got out of hand. It would assuredly take care of two patients.
But a Med Ship man would also have known that it was simply one of those scrupulous precautions a Med Ship man takes when using cultures from store.
Calhoun put the sample away and called Maril back.
"It was nothing," he explained, "but you might have feltuncomfortable. We simply had a bit of Med Service routine that had to be gone through. It's all right now."
He offered no further explanation. She said, "I'll fix lunch." She hesitated. "You brought some food from the first Weald ship. Do you want to—"
He shook his head.
"I'm squeamish," he admitted. "The trouble on Dara is Med Service fault. Before my time, but still ... I'll stick to rations until everybody eats."
He watched her unobtrusively as the day went on. Presently he considered that she was slightly flushed. Shortly after the evening meal of singularly unappetizing Darian rations, she drank thirstily. He did not comment. He brought out cards and showed her a complicated game of solitaire in which mental arithmetic and expert use of probability increased one's chance of winning.
By midnight she'd learned the game and played it absorbedly. Calhoun was able to scrutinize her without appearing to do so, and he was satisfied again. When he mentioned that the Med Ship should arrive off Dara in eight hours more, she put the cards away and went into the other cabin.
Calhoun wrote up the log. He added the notes that Maril had made for him, of Murgatroyd's pulse and blood pressure after the injection of the same culture that produced fever and thirstiness in himself and later, without contact with him or the culture, in Maril. He put a professional comment at the end:
The culture seems to have retained its normal characteristics during long storage in the spore state. It received and reproduced rapidly. I injected .5 cc. under my skin and in less than one hour my temperature was 30.8° C. An hour later it was 30.9° C. This was its peak. It immediately returned to normal. The only other observable symptom was slightly increased thirst. Bloodpressure and pulse remained normal. The other person in the Med Ship displayed the same symptoms, in prompt and complete repetition, without physical contact.

He went to sleep, with Murgatroyd curled up in his cubbyhole, his tail draped carefully over his nose.
The Med Ship broke out of overdrive at 1300 hours, ship-time. Calhoun made contact with the grid and was promptly lowered to the ground.
It was almost two hours later, at 1500 hours ship-time, when the people of Dara were informed by broadcast that Calhoun was to be executed immediately.
From the viewpoint of Darians, who were also blueskins, the decision of Calhoun's guilt and the decision to execute him were reasonable enough. Maril protested fiercely, and her testimony agreed with Calhoun's in every respect, but from a blueskin viewpoint their own statements were damning.
Calhoun had taken four young astrogators to space. They were the only semiskilled space pilots Dara had. There were no fully qualified men. Calhoun had asked for them, and taken them out to emptiness, and there he had instructed them in modern guidance methods for ships of space.
So far there was no disagreement. He'd proposed to make them more competent pilots; more capable of driving a ship to Orede, for example, to raid the enormous cattle herdsthere. And he'd had them drive the Med Ship to Weald, against which there could be no objection.
But just before arrival he had tricked all four of them by giving them drugged coffee. He'd destroyed the lethal bacterial cultures they'd been ordered to dump on Weald. Then he'd sent the four student pilots off separately, so he and Maril claimed, in huge ships crammed with grain. But those ships were not to be believed in, anyhow.
Nobody believed in shiploads of grain to be had for the taking. They did know that the only four partially experienced space pilots on Dara had been taken away and by Calhoun's own story sent out of the ship after they'd been drugged.
Had they been trained, and had they been helped or even permitted to sow the seeds of plague on Weald, and had they come back prepared to pass on training to other men to handle other space ships now feverishly being built in hidden places on Dara, then Dara might have a chance of survival.
But a space battle with only partly trained pilots would be hazardous at best. With no trained pilots at all, it would be hopeless. So Calhoun, by his own story, appeared to have doomed every living being on Dara to massacre from the bombs of Weald.
It was this last angle which destroyed any chance of anybody believing in such fairy-tale objects as ships loaded down with grain. Calhoun had shattered Dara's feeble hope of resistance. Weald had some ships and could build or buy others faster than Dara could hope to construct them.
Equally important, Weald had a plenitude of experienced spacemen to man some ships fully and train the crews of others. If it had become desperately busy fighting plague, then a fleet to exterminate life on Dara would be delayed.Dara might have gained time at least to build ships which could ram their enemies and destroy them that way.
But Calhoun had made it impossible. If he told the truth and Weald already had a fleet of huge ships which only needed to be emptied of grain and filled with guns and men, then Dara was doomed. But if he did not tell the truth it was equally doomed by his actions. So Calhoun would be killed.
His execution was to take place in the open space of the landing-grid, with vision cameras transmitting the sight over all the blueskin planet. Half-starved men with grisly blue blotches on their skins, marched him to the center of the largest level space on the planet which was not desperately being cultivated. Their hatred showed in their expressions. Bitterness and fury surrounded Calhoun like a wall. Most of Dara would have liked to have seen him killed in a manner as atrocious as his crime, but no conceivable death would be satisfying.
So the affair was coldly businesslike, with not even insults offered to him. He was left to stand alone in the very center of the landing-grid floor. There were a hundred blasters which would fire upon him at the same instant. He would not only be killed; he would be destroyed. He would be vaporized by the blue-white flames poured upon him.
His death was remarkably close, nothing remaining but the order to fire, when loudspeakers from the landing-grid office froze everything. One of the grain ships from Weald had broken out of overdrive and its pilot was triumphantly calling for landing coordinates. The grid office relayed his call to loudspeaker circuits as the quickest way to get it on the communication system of the whole planet.
"Calling ground," boomed the triumphant voice of the first of the student pilots Calhoun had trained. "Calling ground! Pilot Franz in captured ship requests coordinates for landing! Purpose of landing is to deliver half a million bushels of grain captured from the enemy!"
At first, nobody dared believe it. But the pilot could be seen on vision. He was known. No blueskin would be left alive long enough to be used as a decoy by the men of Weald! Presently the giant ship on its second voyage to Dara—the first had been a generation ago, when it threatened death and destruction—appeared as a dark pinpoint in the sky. It came down and down, and presently it hovered over the center of the tarmac, where Calhoun composedly stood on the spot where he was to have been executed.
The landing-grid crew shifted the ship to one side, and only then did Calhoun stroll in a leisurely fashion toward the Med Ship by the grid's metal-lace wall.
The big ship touched ground, and its exit port revolved and opened, and the student pilot stood there grinning and heaving out handfuls of grain. There was a swarming, yelling, deliriously triumphant crowd, then, where only minutes before there'd been a mob waiting to rejoice when Calhoun's living body exploded into flame.
They no longer hated Calhoun, but he had to fight his way to the Med Ship, nevertheless. He was surrounded by ecstatically admiring citizens of Dara. They shouted praise and rejoicing in his ears until he was half-deafened, and they almost tore his clothing from them in their desire to touch, to pat, to assure him of their gratitude and affection, minutes since they'd thirsted for his blood.
Two hours after the first ship, a second landed. Dara went wild again. Four hours later still, the third arrived. The fourth came down to ground on the following day.
When Calhoun faced the executive and cabinet of Dara for the second time his tone and manner were very dry.
"Now," he said curtly, "I would like a few more astrogatorsto train. I think it likely that we can raid the Wealdian grain fleet one more time, and in so doing get the beginning of a fleet for defense. I insist, however, that it must not be used in combat. We might as well be sensible about this situation! After all, four shiploads of grain won't break the famine! They'll help a lot, but they're only the beginning of what's needed for a planetary population!"
"How much grain can we hope for?" demanded a man with a blue mark covering all his chin.
Calhoun told him.
"How long before Weald can have a fleet overhead, dropping fusion bombs?" demanded another, grimly.
Calhoun named a time. But then he said, "I think we can keep them from dropping bombs if we can get the grain fleet and some capable astrogators."
"How?"
He told them. It was not possible to tell the whole story of what he considered sensible behavior. An emotional program can be presented and accepted immediately. A plan of action which is actually intelligent, considering all elements of a situation, has to be accepted piecemeal. Even so, the military men growled.
"We've plenty of heavy elements," said one. "If we'd used our brains, we'd have more bombs than Weald can hope for! We could turn that whole planet into a smoking cinder!"
"Which," said Calhoun acidly, "would give you some satisfaction but not an ounce of food! And food's more important than satisfaction. Now, I'm going to take off for Weald again. I'll want somebody to build an emergency device for my ship, and I'll want the four pilots I've trained and twenty more candidates. And I'd like to have some decent rations! The last trip brought back two million bushels of grain. You can certainly spare adequate food for twenty men for a few days!"
It took some time to get the special device constructed, but the Med Ship lifted in two days more. The device for which it had waited was simply a preventive of the disaster overtaking the ship from the mine on Orede. It was essentially a tank of liquid oxygen, packed in the space from which stores had been taken away. When the ship's air supply was pumped past it, first moisture and then CO2froze out.
Then the air flowed over the liquefied oxygen at a rate to replace the CO2with more useful breathing material. Then the moisture was restored to the air as it warmed again. For so long as the oxygen lasted, fresh air for any number of men could be kept purified and breathable. The Med Ship's normal equipment could take care of no more than ten. But with this it could journey to Weald with almost any complement on board.
Maril stayed on Dara when the Med Ship left. Murgatroyd protested shrilly when he discovered her about to be closed out by the closing airlock.
"Chee!" he said indignantly. "Chee! Chee!"
"No," said Calhoun. "We'll be crowded enough anyhow. We'll see her later."
He nodded to one of the first four student pilots, who crisply made contact with the landing-grid office, and very efficiently supervised as the grid took the ship up. The other three of the four first-trained men explained every move to sub-classes assigned to each. Calhoun moved about, listening and making certain that the instruction was up to standard.
He felt queer, acting as the supervisor of an educational institution in space. He did not like it. There were twenty-four men beside himself crowded into the Med Ship's small interior. They got in each other's way. They trampled on each other. There was always somebody eating, and always somebody sleeping, and there was no need whatever for the background tape to keep the ship from being intolerably quiet. But the air system worked well enough, except once when the reheating unit quit and the air inside the ship went down below freezing before the trouble could be found and corrected.
The journey to Weald, this time, took seven days because of the training program in effect. Calhoun bit his nails over the delay. But it was necessary for each of the students to make his own line-ups on Weald's sun, and compute distances, and for each of them to practise maneuverings that would presently be called for. Calhoun hoped desperately that preparations for active warfare did not move fast on Weald.
He believed, however, that in the absence of direct news from Dara, Wealdian officials would take the normal course of politicos. They had proclaimed the ship from Orede an attack from Dara. Therefore, they would specialize on defensive measures before plumping for offense. They'd get patrol ships out to spot invasion ships long before they worked on a fleet to destroy the blueskins. It would meet the public demand for defense.
Calhoun was right. The Med Ship made its final approach to Weald under Calhoun's own control. He'd made brightness-measurements on his previous journey and he used them again. They would not be strictly accurate, because a sunspot could knock all meaning out of any reading beyond two decimal places. But the first breakout was just far enough from the Wealdian system for Calhoun to be able to pick out its planets with the electron telescope at maximum magnification. He could aim for Weald itself, allowing, of course, for the lag in the apparent motion of its image because of the limited speed of light. He tried the briefest of overdrive hops, and came out within the solar system and well inside any watching patrol.
That was pure fortune. It continued. He'd broken through the screen of guard ships in undetectable overdrive. He was within half an hour's solar system drive of the grain fleet. There was no alarm, at first. Of course radars spotted the Med Ship as an object, but nobody paid attention. It was not headed for Weald. It was probably assumed to be a guard boat itself. Such mistakes do happen.
Again from the storage space from which supplies had been removed, Calhoun produced vacuum suits. The four first students went out, each escorting a less-accustomed neophyte and all fastened firmly together with space ropes. They warmed the interiors of four ships and went on to others. Presently there were eight ships making ready for an interstellar journey, each with a scared but resolute new pilot familiarizing himself with its controls. There were sixteen ships. Twenty. Twenty-three.
A guard ship came humming out from Weald. It would be armed, of course. It came droning, droning up the forty-odd thousand miles from the planet. Calhoun swore. He could not call his students and tell them what was toward. The guard ship would overhear. He could not trust untried young men to act rationally if they were unaware and the guard ship arrived and matter-of-factly attempted to board one of them.
Then he was inspired. He called Murgatroyd, placed him before the communicator, and set it at voice-only transmission. This was familiar enough, to Murgatroyd. He'd often seen Calhoun use a communicator.
"Chee!" shrilled Murgatroyd. "Chee-chee!"
A startled voice came out of the speaker: "What's that?"
"Chee," said Murgatroyd zestfully.
The communicator was talking to him. Murgatroyd adored three things, in order. One was Calhoun. The second was coffee. The third was pretending to converse like a humanbeing. The speaker said explosively, "You there, identify yourself!"
"Chee-chee-chee-chee!" observed Murgatroyd. He wriggled with pleasure and added, reasonably enough, "Chee!"
The communicator bawled, "Calling ground! Calling ground! Listen to this! Something that ain't human's talking at me on a communicator! Listen in an' tell me what to do!"
Murgatroyd interposed with another shrill, "Chee!"
Then Calhoun pulled the Med Ship slowly away from the clump of still-lifeless grain ships. It was highly improbable that the guard boat would carry an electron telescope. Most likely it would have only an echo-radar, and so could determine only that an object of some sort moved of its own accord in space. Calhoun let the Med Ship accelerate. That would be final evidence. The grain ships were between Weald and its sun. Even electron telescopes on the ground—and electron telescopes were ultimately optical telescopes with electronic amplification—could not get a good image of the ship through sunlit atmosphere.
"Chee?" asked Murgatroyd solicitously. "Chee-chee-chee?"
"Is it blueskins?" shakily demanded the voice from the guard boat. "Ground! Ground! Is it blueskins?"
A heavy, authoritative voice came in with much greater volume. "That's no human voice," it said harshly. "Approach its ship and send back an image. Don't fire first unless it heads for ground."
The guard ship swerved and headed for the Med Ship. It was still a very long way off.
"Chee-chee," said Murgatroyd encouragingly.
Calhoun changed the Med Ship's course. The guard ship changed course too. Calhoun let it draw nearer, but only a little. He led it away from the fleet of grain ships.
He swung his electron telescope on them. He saw a spacesuited figure outside one, safely roped, however. It was easy to guess that someone had meant to return to the Med Ship for orders or to make a report, and found the Med Ship gone. He'd go back inside and turn on a communicator.
"Chee!" said Murgatroyd.
The heavy voice boomed. "You there! This is a human-occupied world! If you come in peace, cut your drive and let our guard ship approach!"
Murgatroyd replied in an interested but doubtful tone. The booming voice bellowed. Another voice of higher authority took over. Murgatroyd was entranced that so many people wanted to talk to him. He made what for him was practically an oration. The last voice spoke persuasively and suavely.
"Chee-chee-chee-chee," said Murgatroyd.
One of the grain ships flickered and ceased to be. It had gone into overdrive. Another. And another. Suddenly they began to flick out of sight by twos and threes.
"Chee," said Murgatroyd with a note of finality.
The last grain ship vanished.
"Calling guard ship," said Calhoun dryly. "This is Med ShipAesclipus Twenty. I called here a couple of weeks ago. You've been talking to mytormal, Murgatroyd."
A pause. A blank pause. Then profanity of deep and savage intemperance.
"I've been on Dara," said Calhoun.
Dead silence fell.
"There's a famine there," said Calhoun deliberately. "So the grain ships you've had in orbit have been taken away by men from Dara—blueskins if you like—to feed themselves and their families. They've been dying of hunger and they don't like it."
There was a single burst of the unprintable. Then theformerly suave voice said waspishly, "Well? The Med Service will hear of your interference!"
"Yes," said Calhoun. "I'll report it myself. I have a message for you. Dara is ready to pay for every ounce of grain and for the ships it was stored in. They'll pay in heavy metals—irridium, uranium, that sort of thing."
The suave voice fairly curdled.
"As if we'd allow anything that was ever on Dara to touch ground here!"
"Ah! But there can be sterilization. To begin with metals, uranium melts at 1150° centigrade, and tungsten at 3370° and irridium at 2350°. You could load such things and melt them down in space and then tow them home. And you can actually sterilize a lot of other useful materials!"
The suave voice was infuriated: "I'll report this! You'll suffer for this!"
Calhoun said pleasantly, "I'm sure that what I say is being recorded, so that I'll add that it's perfectly practical for Wealdians to land on Dara, take whatever property they think wise—to pay for damage done by blueskins, of course—and get back to Wealdian ships with absolutely no danger of carrying contagion. If you'll make sure the recording's clear...."
He described, clearly and specifically, exactly how a man could be outfitted to walk into any area of any conceivable contagion, do whatever seemed necessary in the way of looting—but Calhoun did not use the word—and then return to his fellows with no risk whatever of bringing back infection. He gave exact details.
Then he said, "My radar says you've four ships converging on me to blast me out of space. I sign off."
The Med Ship disappeared from normal space, and entered that improbably stressed area of extension which it formed about itself and in which physical constants were wildlystrange. For one thing, the speed of light in overdrive-stressed space had not been measured yet. It was too high. For another, a ship could travel very many times 186,000 miles per second in overdrive.
The Med Ship did just that. There was nobody but Calhoun and Murgatroyd on board. There was companionable silence, with only the small threshold-of-perception sounds which one did not often notice.
Calhoun luxuriated in regained privacy. For seven days he'd had twenty-four other human beings crowded into the two cabins of the ship, with never so much as one yard of space between himself and someone else. One need not be snobbish to wish to be alone sometimes!
Murgatroyd licked his whiskers thoughtfully.
"I hope," said Calhoun, "that things work out right. But they may remember on Dara that I'm responsible for some ten million bushels of grain reaching them. Maybe, just possibly, they'll listen to me and act sensibly. After all, there's only one way to break a famine. Not with ten million bushels for a whole planet! And certainly not with bombs!"
Driving direct, without pausing for practising, the Med Ship could arrive at Dara in a little more than five days. Calhoun looked forward to relaxation. As a beginning he made ready to give himself an adequate meal for the first time since first landing on Dara. Then, presently, he sat down to a double meal of Darian famine-rations, which were far from appetizing. But there wasn't anything else on board.
He had some pleasure later, though, envisioning what went on in the normal, non-overdrive universe. Suns flared, and comets hurtled on their way, and clouds formed and dropped down rain, and all sorts of celestial and meteorological phenomena took place. On Weald, obviously, there would be purest panic.
The vanishing of the grain fleet wouldn't be charged against twenty-four men. A Darian fleet would be suspected, and with the suspicion would come terror, and with terror a governmental crisis. Then there'd be a frantic seizure of any craft that could take to space, and the agitated improvisation of a space fleet.
But besides that, biological-warfare technicians would examine Calhoun's instructions for equipment by which armed men could be landed on a plague-stricken planet and then safely taken off again. Military and governmental officials would come to the eminently sane conclusion that while Calhoun could not well take active measures against blueskins, as a sane and proper citizen of the galaxy he would be on the side of law and order and propriety and justice—in short, of Weald. So they ordered sample anticontagion suits made according to Calhoun's directions, and they had them tested. They worked admirably.
On Dara, while Calhoun journeyed placidly back to it, grain was distributed lavishly, and everybody on the planet had their cereal ration almost doubled. It was still not a comfortable ration, but the relief was great. There was considerable gratitude felt for Calhoun, which as usual included a lively anticipation of further favors to come. Maril was interviewed repeatedly, as the person best able to discuss him, and she did his reputation no harm. That was all that happened on Dara....
No. There was something else. A very curious thing, too. There was a spread of mild symptoms which nobody could exactly call a disease. They lasted only a few hours. A person felt slightly feverish, and ran a temperature which peaked at 30.9° centigrade, and drank more water than usual. Then his temperature went back to normal and he forgot all about it. There have always been such trivial epidemics. They arerarely recorded, because few people think to go to a doctor. That was the case here.
Calhoun looked ahead a little, too. Presently the fleet of grain ships would arrive and unload and lift again for Orede, and this time they would make an infinity of slaughter among wild cattle herds, and bring back incredible quantities of fresh-slaughtered frozen beef. Almost everybody would get to taste meat again, which would be most gratifying.
Then, the industries of Dara would labor at government-required tasks. An astonishing amount of fissionable material would be fashioned into bombs—a concession by Calhoun—and plastic factories would make an astonishing number of plastic sag-suits. And large shipments of heavy metals in ingots would be made to the planet's capital city and there would be some guns and minor items.
Perhaps somebody could have predicted any of these items in advance, but it was unlikely that anyone did. Nobody but Calhoun, however, would ever have put them together and hoped very urgently that things would work out. He could see a promising total result. In fact, in the Med Ship hurtling through space, on the fourth day of his journey, he thought of an improvement that could be made in the sum of all those happenings when they got mixed together.
He got back to Dara. Maril came to the Med Ship. Murgatroyd greeted her with enthusiasm.
"Something strange has happened," said Maril, very much subdued. "I told you that sometimes blueskin markings fade out on children, and then neither they nor their children ever have markings again."
"Yes," said Calhoun. "I remember that you told me."
"And you were reminded of a group of viruses on Tralee. You said they only took hold of people in terribly bad physical condition, but then they could be passed on from mother to child, until sometimes they died out."
Calhoun blinked.
"Yes?"
"Korvan," said Maril very carefully. "Has worked out an idea that that's what happens to the blueskin markings on Darians. He thinks that people almost dead of the plague could get the virus, and if they recovered from the plague pass the virus on and be blueskins."
"Interesting," said Calhoun, noncommittally.
"And when we went to Weald," said Maril very carefully indeed, "you were working with some culture material. You wrote quite a lot about it in the ship's log. You gave yourself an injection. Remember? And Murgatroyd? You wrote down your temperature, and Murgatroyd's?" She moistened her lips. "You said that if infection passed between us, something would be very infectious indeed?"
"This is a long discussion," said Calhoun. "Does it arrive at a point?"
"It does," said Maril. "Thousands of people are having their pigment-spots fade away. Not only children but grownups. And Korvan has found out that it always seems to happen after a day when they felt feverish and very thirsty, and then felt all right again. You tried out something that made you feverish and thirsty. I had it too, in the ship. Korvan thinks there's been an epidemic of something that is obliterating the blue spots on everybody that catches it. There are always trivial epidemics that nobody notices. Korvan's found evidence of one that's makingblueskinno longer a word with any meaning."
"Remarkable!" said Calhoun.
"Did you do it?" asked Maril. "Did you start a harmless epidemic that wipes out the virus that makes blueskins?"
Calhoun said in feigned astonishment, "How can you think such a thing, Maril?"
"Because I was there," said Maril. She said, somehow desperately, "I know you did it! But the question is, are you going to tell? When people find they're not blueskins any longer, when there's no such thing as a blueskin any longer, will you tell them why?"
"Naturally not," said Calhoun. "Why?" Then he guessed. "Has Korvan—"
"He thinks," said Maril, "that he thought it up all by himself. He's found the proof. He's very proud. I'd have to tell him how the ideas got into his head if you were going to tell. And he'd be ashamed and angry."
Calhoun considered, staring at her.
"How it happened doesn't matter," he said at last. "The idea of anybody doing it deliberately would be disturbing, too. It shouldn't get about. So it seems much the best thing for Korvan to discover what's happened to the blueskin pigment, and how it happened. But not why."
She read his face carefully.
"You aren't doing it as a favor to me," she decided. "You'd rather it was that way."
She looked at him for a long time, until he squirmed. Then she nodded and went away.
An hour later the Wealdian space fleet was reported massed in space and driving for Dara.
