In theory one can perform heavy work while clad in radiation armor. One can do so in practice—provided that one has been through a rigorous course of training. Pendeen, Second Engineer of Rim Mamelute, had been so trained. So, of course, had been Mr. Williams—but Grimes had insisted that the Mate stay aboard the tug while he, with Sonya and the engineer, effected an entry into the hull of the derelict. Soon, while the boarding party was making its exploratory walk over the stranger ship's shell plating, he had been obliged to order Williams to cut the drive; sufficient velocity had been built up so that both vessels were now in Free Fall away from the sun.
Even in Free Fall it was bad enough. Every joint of the heavy suit was stiff, every limb had so much mass that great physical effort was required to conquer inertia. Weary and sweating heavily, Grimes forced himself to keep up with his two companions, by a great effort of will contrived to maintain his side of the conversation in a voice that did not betray his poor physical condition—
He was greatly relieved when they discovered, towards the stern, what was obviously an airlock door. Just a hair-thin crack in the plating it was, outlining a circular port roughly seven feet in diameter. There were no signs of external controls, and the crack was too thin to allow the insertion of any tool.
"Send for the bell, sir?" asked Pendeen, his normally deep voice an odd treble in Grimes' helmet phones.
"The bell? Yes, yes. Of course. Carry on, Mr. Pendeen."
"Al to Bill," Grimes heard. "Do you read me? Over."
"Bill to Al. Loud an' clear. What can I do for you?"
"We've found the airlock. But we want the bell."
"You would. Just stick around. It'll be over."
"And send the cutting gear while you're about it."
"Will do. Stand by."
"Had any experience with the Laverton Bell, sir?" asked Pendeen, his voice not as respectful as it might have been.
"No. No actual working experience, that is."
"I have," said Sonya.
"Good. Then you'll know what to do when we get it."
Grimes, looking towards Rim Mamelute, could see that something bulky was coming slowly towards them along one of the tow wires, the rocket that had given the packet its initial thrust long since burned out. He followed the others towards the stem of the derelict, but stood to one side, held to the plating by the magnetic soles of his boots, as they unclipped the bundle from the line. He would have helped them to carry it back aft, but they ignored him.
Back at the airlock valve, Sonya and Pendeen worked swiftly and competently, releasing the fastenings, unfolding what looked like a tent of tough white plastic. This had formed the wrapper for other things—including a gas bottle, a laser torch and a thick tube of adhesive. Without waiting for instructions Sonya took this latter, removed the screw cap and, working on her hands and knees, used it to describe a glistening line just outside the crack that marked the door. Then all three of them, standing in the middle of the circle, lifted the fabric above their heads, unfolding it as they did so. Finally, with Grimes and Pendeen acting as tent poles, Sonya neatly fitted the edge of the shaped canopy to the ring of adhesive, now and again adding a further gob of the substance from the tube.
"Stay as you are, sir," the engineer said to Grimes, then fell to a squatting position. His gloved hands went to the gas cylinder, to the valve wheel. A white cloud jetted out like a rocket exhaust, then faded to invisibility. Around the boarding party the walls of the tent bellied outwards, slowly tautened, distended to their true shape by the expanding helium. Only towards the end was the hiss of the escaping gas very faintly audible.
Pendeen shut the valve decisively, saying, "That's that. Is she all tight, Sonya?"
"All tight, Al," she replied.
"Good." With a greasy crayon he drew a circle roughly in the center of the airlock door, one large enough to admit a spacesuited body. He picked up the laser torch, directed its beam downwards, thumbed the firing button. The flare of vaporizing metal was painfully bright, outshining the helmet lights, reflected harshly from the white inner surface of the plastic igloo. There was the illusion of suffocating heat—or was it more than only an illusion? Pendeen switched off the torch and straightened, looking down at the annulus of still-glowing metal. With an effort he lifted his right foot, breaking the contact of the magnetized sole with the plating. He brought the heel down sharply. The clang, transmitted through the fabric of their armor, was felt rather than heard by the others.
And then the circular plate was falling slowly, into the darkness of the airlock chamber, and the rough manhole was open so that they could enter.
Grimes was first into the alien ship, followed by Sonya and then Pendeen. It was light enough in the little compartment once they were into it, the beams of their helmet lights reflected from the white-painted walls. On the inner door there was a set of manual controls that worked—once Grimes realized that the spindle of the wheel had a left handed thread. Beyond the inner door there was an alleyway, and standing there was a man.
The Commodore whipped the pistol from his holster, his reflexes more than compensating for the stiffness of the joints of his suit. Then, slowly, he returned the weapon to his belt. This man was dead. Radiation may have killed him, but it had not killed all the bacteria of decay present in his body. Some freak of inertial and centrifugal forces, coming into play when the derelict had been taken in tow, had flung him to a standing posture, and the magnetic soles of his rough sandals—Grimes could see the gleam of metal—had held him to the deck.
So he was dead, and he was decomposing, his skin taut and darkly purple, bulging over the waistband of the loincloth—it looked like sacking—that was his only clothing. He was dead—and Grimes was suddenly grateful for the sealed suit that he was wearing, the suit that earlier he had been cursing, that kept out the stench of him.
Gently, with pity and pointless tenderness, he put his gloved hands to the waist of the corpse, lifted it free of the deck, shifted it to one side.
"We must be just above engineroom level," said Sonya, her voice deliberately casual.
"Yes," agreed Grimes. "I wonder if this ship has an axial shaft. If she has, it will be the quickest way of getting to the control room."
"That will be the best place to start investigations," she said.
They moved on through the alleyway, using the Free Fall shuffle that was second nature to all of them, letting the homing instinct that is part of the nature of all spacemen guide them. They found more bodies, women as well as men, sprawled in untidy attitudes, hanging like monstrous mermen and merwomen in a submarine cave. They tried to ignore them, as they tried to ignore the smaller bodies, those of children, and came at last, at the end of a short, radial alleyway, to the stout pillar of the axial shaft.
There was a door in the pillar, and it was open, and one by one they passed through it and then began pulling themselves forward along the central guide rod, ignoring the spiral ramp that lined the tunnel. Finally they came to a conventional enough hatchway, but the valve sealing the end of the shaft was jammed. Grimes and Sonya fell back to let Pendeen use the laser torch. Then they followed him into the control room.
