Again a long, long wait before anything happened. Then there was a loud, distinct clanking against the Med Ship's hull. Calhoun moved quickly. He couldn't have been seen from the communicator before, and he'd wanted to hear anything that came to the Med Ship. Now it would probably be boarded, but he did not want to be seen until he had more information.
He went into the sleeping cabin and closed the door behind him. He stopped at a very small cupboard and put something in his pocket. He entered a tall closet where his uniforms hung stiffly. He closed that door. He waited.
More clankings. At least two spacesuited figures had landed on the Med Ship's hull-plating. They'd still have long, slender space ropes leading back to their own ship. They clanked their way along the hull to the open airlock door. Calhoun heard the changed sound of their magnetic shoe soles as they entered the air-lock. They'd loosen the space ropes now and close the door. They did. He heard the sound of the outer door sealing itself. There was the hissing of air going into the lock.
Then the inner door opened. Two figures came out. They'd be carrying blasters at the ready as they emerged. Then he heard Murgatroyd.
"Chee-chee-chee! Chee!"
He wouldn't know exactly how to act. He normally took his cue from Calhoun. He was a friendly little animal. He had never received anything but friendliness from humans, and of course he couldn't imagine anything else. So he performed the honors of the ship with a grand air. He welcomed the newcomers. He practically made a speech of cordial greeting.
Then he waited hopefully to see if they'd brought him any sweet cakes or coffee. He didn't really expect it, but a tormal can always dream.
They hadn't brought gifts for Murgatroyd. They didn't even respond to his greeting. A tormal was standard on a Med Ship. They ignored him. Calhoun heard the clickings as spacesuit faceplates opened.
"Evidently," said a rumbling voice, "he's gone. Very neat. Nothing to clean up. Not even anything unpleasant to remember."
A second voice said curtly, "It'll be unpleasant if I don't cut off the rest of it!"
There was a snapping sound, as if a wire had forcibly been torn free from something. It was probably a cable to the control-board which, in the place of a rarely or never used switch, had connected something not originally intended, but which if the cable were broken could not act. Most likely the snapping of this wire should return the ship to a proper control-central system's guidance and operation. It did.
"Hm," said the first voice, "there's Kryder on the screens, and there's our ship. Everything's set."
"Wait!" commanded the curt voice. "I take no chances, I'm going to cut that thing off down below!"
Someone moved away. He wore a spacesuit. The faint creaking of its constant volume joints were audible. He left the control-room. His magnetic shoes clanked on uncarpeted metal steps leading down. He was evidently headed for the mechanical and electronic section of the ship. Calhoun guessed that he meant to cut completely loose the extra, gimmicked control-central unit that had operated the ship through the stages that should have led to his death. Apparently it could still destroy itself and the Med Ship.
The other man moved about the cabin. Calhoun heard Murgatroyd say, "Chee-chee!" in a cordial tone of voice. The man didn't answer. There are people to whom all animals, and even tormals are merely animate objects. There was suddenly the rustling of paper. He'd found the data sheets Calhoun had been studying to the very last instant before breakout.
Clankings. The man with the curt voice came back from below.
"I fixed it," he said shortly. "It can't blow now!"
"Look here!" said the rumbling voice, amused. "He had reports about your Med Ship on Castor IV!" He quoted sardonically, "It has to be assumed that a blaster was fired inside the ship. In any event the ship's fuel stores blew and shattered it to atoms. There is no possibility for more than guesses as to the actual cause of the disaster. The Med Ship's doctor was evidently killed, and there was some panic. The destruction of a large sum in currency, which the Med Ship was to have left off at a nearby planet to secure the shipment of uncontaminated foodstuffs to Castor IV, caused some delay in the restoration of normal health and nourishment on the planet. However—" The rumbling voice chuckled. "That's Kelo! Kelo wrote this report!"
The curt voice said, "I'm going to check things."
Calhoun heard the sounds of a thorough checkover, from air apparatus to space communicator. Then the ship was swung about, interplanetary drive went on and off and somebody who knew Med Ships made sure that the Aesclipus Twenty responded properly to all controls. Then the curt voice said, "All right. You can go now."
One man went to the air-lock and entered it. The lock-pumps boomed and stopped. The outer lock door opened and closed. The man left behind evidently got out of his spacesuit. He carried it below. He left it. He returned as the rumbling voice came out of a speaker, "I'm back on our ship. You can go now."
"Thanks," said the curt voice, sarcastically.
Calhoun knew that the newcomer to the ship had seated himself at the control-board. He heard Murgatroyd say, almost incredulously, "Chee? Chee?"
"Out of my way!" snapped the curt voice.
Then the little Med Ship swung, and seemed to teeter very delicately as it was aimed with very great care close to the nearby yellow star. Before, the ship's screens had untruthfully insisted that Med Service Headquarters surrounded the ship. Now they worked properly. There were stars by myriads of myriads, and they looked as if they might be very close. Yet the bright yellow sun would be the nearest, and it was light-hours away. A light-hour is the distance a ray of light will travel, at a hundred eighty-odd thousand miles per second, during thirty-six hundred of them.
There was a sensation of shocking dizziness and intolerable nausea, swiftly repeated as the Med Ship made an overdrive hop to carry it only a few light-hours. Then there was that appalling feeling of contracting spiral fall. Murgatroyd said protestingly, "Chee!"
Then Calhoun moved quietly out of the closet into the sleeping cabin, and then out of that. He was more than halfway to the control-board before the man seated there turned his head. Then Calhoun leaped ferociously. He had a pocket blaster in his hand, but he didn't want to use it if it could be helped.
It was just as effective as a set of brass knuckles would have been, though. Before the other man regained consciousness, Calhoun had him very tidily bound and was looking interestedly over the contents of his pockets. They were curious. Taken literally, they seemed to prove that the man now lying unconscious on the floor was a Med Ship man on professional assignment, and that he was entitled to exercise all the authority of the Med Service itself.
On the word of his documents, he was considerably more of a Med Ship man than Calhoun himself.
"Curiouser and curiouser!" observed Calhoun to Murgatroyd. "I'd say that this is one of those tangled webs we weave when first we practice to deceive. But what's going on?"
III
The Aesclipus Twenty hovered, using emergency rocket fuel lavishly while her motion relative to the ground below her carried her past a ridge of high, snow clad mountains and then over a shoreline with pack ice piled against its beaches.
This was not the planet from which a call had been sent and which Calhoun was answering. There was no sign of habitation anywhere. Cold blue sea swept past below. There were some small ice cakes here and there, but as the shore was left behind they dwindled in number and the water surface became unbroken save by waves. The mountains sank to the horizon, and then ahead—in the direction of the Med Ship's motion—an island appeared. It was small and rocky and almost entirely snow-covered. There was no vegetation. It was entirely what Calhoun had expected from his examination by electron telescope from space.
