Pariah Planet

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 infective 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!"

"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 was perfectly 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 with it 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?"

She went disturbedly into the other cabin. Calhoun drew a 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 and offered no explanation. She said;

"I'll fix lunch." She hesitated. "You brought some food from the first Weald ship. Do you want it?"

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, ship-time, 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 revived 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. Blood-pressure 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.

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 – 1500 hours ship-time – when the people of Dara were informed by broadcast that Calhoun was publicly to be executed; immediately.

CHAPTER 7

From the viewpoint of Darians, 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 semi-skilled 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-herds there. 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 on Dara could imagine stores of food bought up and stored away because it was useless; to keep up prices. 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, – why – 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 – why – 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 see 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 remained 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-coördinates. 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 coördinates for landing! Purpose of landing, 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 handsful 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 now-ecstatically admiring citizens of Dara, only 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 on the following day.

Then 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 astrogators to train. I think it likely that we can raid the Wealdian grain-fleet one time more, 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."

"What do you have in mind?"

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, with one eye and half his forehead colored blue. "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! When the last trip brought back two million bushels of grain, you can 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 CO2 froze out. Then the air flowed over the liquefied oxygen at a rate to replace the CO2 with 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 lock-door.

"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, and he crisply made contact with the landing-grid office. He 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 reheater 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 – or massacre – 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 deathship 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 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. It reached the grain-fleet.

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 happening. The guard-ship would overhear. He could not trust untried young men to act rationally if they were unwarned 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 human being. 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 – even electron telescopes on the ground 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 space-suited 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 drily. "This is Med ship Aesclipus Twenty. I called here a couple of weeks ago. You've been talking to my tormal, 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 the formerly 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, – iridium, 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 iridium 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 said infuriatedly;

"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 wildly strange. 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 186000 miles per second in overdrive.
