his own voice. “I’m afraid not,” he said harshly. “It’s your brother, yes. But—he wouldn’t be asleep. No. He’s not asleep.”
    He wasn’t. He was dead.

CHAPTER FOUR
    Dunne anchored the lifeboat to a projecting knob of faceted stone, casting a loop from the airlock door with a spaceman’s—specifically, a space-miner’s—trick of getting the loop into existence and then floating it to the thing to be gripped. It caught, and he gently brought the lifeboat close. He knotted the rope and went back into the lifeboat. Nike waited there, totally pale.
    “Listen to me!” said Dunne sternly. “I’m going to see what’s happened. You stay here! You can listen. If you hear a drive or more of those twitterings—I’ll be back! I’ll hear it too in my headphones. But you stay here. Leave the lock-door alone. You can watch through the viewports, but don’t do anything. Not anything!”
    She nodded, watching his expression with something of desperation in her own.
    “Do you think he—”
    “I don’t think anything yet,” said Dunne. “He should have heard us arrive. There was plenty of oxygen. I’ve got to find out what’s wrong.”
    He went into the airlock again and checked—as always—the sealing of his helmet to the vacuum-suit. The suit ballooned out as the airlock pumped empty. There’d been much trouble with space-suits in the early days, when men tried to use full-pressure air in them. They swelled and the suit-arms tended to swing out widely, so that a man in a vacuum-suit was spread-eagled by the air pressure inside. He was like a man-shaped toy balloon, incapable of any purposeful motion. But with only three pounds pressure of oxygen instead of fifteen of oxygen-nitrogen mixture, all suits were manageable. Dunne checked his steering-jet—not to be used if it was possible to avoid it. He checked his belt-weapon. He fastened a lifeline. He went out of the lock, trailing the line behind him.
    With no gravity he couldn’t very well walk. So he crawled toward the bubble, clutching an extrusion of its surface, testing it, and then trusting to it while he reached for another handhold. This was abyssal rock; and where the lifeboat was nearest, it had slowly crystalized under unthinkable pressure. The stone crystals were six to ten inches in length. The rock. as a mass was an intricately interlaced agglomerate of such crystals, ranging through various shades of brown. They had sword-sharp points and edges. A man could rip his vacuum-suit on any of a hundred keen-edged projections in a crawl of a dozen feet.
    All about lay the sunlit mist. There was no solidity anywhere away from this rock and this spaceboat. The gaunt, glittering Ring-fragment and the lifeboat were the only things on which one could focus his eyes. They floated, rotating with enormous deliberation, linked together by a slender cord.
    Dunne reached the bubble. It had been established here to make room for those activities a donkeyship has no room for. There was much gray matrix to a very little crystal-stuff. Much matrix had to be crushed and sifted to recover the crystals it contained. When there was enough material to be worked, one set up a bubble. One brought the gray matrix into the bubble in sacks, and there crushed it and made a first cleaning of the crystals. When there were many tons of the friable gray stuff to be worked, a bubble was much more practical than taking it into a donkeyship.
    Dunne arrived at the bubble. He searched its interior with his eyes. He stayed outside.
    Nike watched from a viewpoint in the control room. Nothing changed inside the bubble. The sleeping bag did not stir. Nothing stirred. Dunne looked like a human fly creeping on something mysteriously suspended from nowhere, from which he could fall to infinity if he missed a single handhold.
    He pressed on the expanded plastic of the bubble. It pushed in. It did not push out again when he took his hand away. Nike watched, uncomprehending. Dunne made
