"Latent impressions," answered Shearing briefly, and sent the skiff skittering in between two great black monoliths, to settle with a jar on a pan of rock as smooth and naked as a ballroom floor.

"Make it fast," said Shearing. "They're right on top of us."

The skiff, designed as Sheering had said for short hops, could not accommodate the extra weight and bulk of an airlock. You were supposed to land in atmosphere. If you didn't, you just pushed a release-b.u.t.ton and hung on. The air was exhausted in one whistling swoosh that took with it everything loose. The moisture in it crystallized instantly, and before this frozen drift had even begun to settle, Hyrst and Shearing were on their way.

They crossed the rock pan in great swaggering bounds. The gravity was light, the horizon only twenty or so miles away. Literally in his mind's eye Hyrst could see the three ships arrowing at them. He opened contact with Vernon, knowing Shearing had done so too. Vernon had been looking for them.

"Mr. Bellaver still prefers to have you alive," he said. "If you'll wait quietly beside the skiff, we'll take you aboard."

Shearing gave him a hard answer.

"Very well," said Vernon. "Mr. Bellaver wants me to make it clear to you that he doesn't intend for you to get away. So you can interpret that as you please. Be seeing you."

He broke contact, knowing that Hyrst and Shearing would close him out.

From now on, Hyrst realized, he would keep track of them the way he and Shearing had kept track of obstructions in the path of flight, by mental "sight". The yacht was extremely close. Suddenly Hyrst had a confused glimpse of a hand on a control-lever over-lapped by a view of the black-mouthed tubes of the yacht's belly-jets. He dived, literally, into a crack between one of the monoliths and a slab that leaned against its base, dragging Shearing with him.

The yacht swept over. Nothing happened. It dropped out of sight, braking for a landing.

"Imagination," said Shearing. "You realize a possibility, and you think it's so. Tricky. But I don't blame you. The safe side is the best one."

Hyrst looked out the crack. One of the tugs was coming in to land beside the skiff, while the other one circled.

"Now what?" he said. "I suppose we can dodge them for a while, but we can't hide from Vernon."

Shearing chuckled. He had got his look of tough competence back. He seemed almost to be enjoying himself. "I told you you were only a cub.

How do you suppose we've kept the starship hidden all these years?

Watch."

In the flick of a second Hyrst went blind and deaf. Then he realized that it was only his mental eyes and ears that were blanked out as though a curtain had been drawn across them. His physical eyes were still clear and sharp, and when Shearing's voice came over the helmet audio he heard it without trouble.

"This is called the cloak. I suppose you could call it an extension of the shield, though it's more like a force field. It's no bar to physical vision, and it has the one great disadvantage of being opaque both ways to mental energy. But it does act as a deflector. If Vernon follows us now, he'll have to do it the hard way. Stick close by me, so I don't have too wide a spread. And it'll be up to you to lead. I can't do both.

Let's go."

Hyrst had, unconsciously, become so used to his new perceptions that it made him feel dull and helpless to be without them. He led off down one of the smooth rock avenues, going away from the skiff and the tug which had just landed.

On either side of the avenue were monoliths, irregularly s.p.a.ced and of different sizes and heights but following an apparently orderly plan.

The light of the distant sun lay raw and blinding on them, casting shadows as black and sharp-edged as though drawn upon the rock with india ink.

You could see faces in the monoliths. You could see mighty outlines, singly and in groups, of G.o.ds and beasts and men, in combat, in suppliance, in death and burial. That was why these asteroids were called Valhallas. Twenty-six of them had been found so far, and studied, and still no one could say certainly whether or not the hands of any living beings had fashioned them. They might be actual monuments, defaced by cosmic dust, by collision with the myriad fragments of the Belt, by time. They might be one of Nature's casual jokes, created by the same agencies. No actual tombs had been found, nor tools, nor definitely identifiable artifacts. But still the feeling persisted, in the airless silence of the avenues, that some pa.s.sing race had paused and wrought for itself a memorial more enduring than its fame, and then gone on into the great galactic sea, never to return.

Hyrst had never been on a Valhalla before. He understood why Shearing had not wanted to land and he wished now that they hadn't. There was something overwhelmingly sad and awesome about these leaning, towering figures of stone, moving forever in their lonely orbit, going nowhere, returning to nowhere.

Then he saw the second tug overhead. He forgot his daydreams. "They're going to act as a spotter," he said. Shearing grunted but did not speak.

His whole mind was concentrated on maintaining the cloak. Hyrst stopped him still in the pitchy shadow under what might have been a kneeling woman sixty feet high. He watched the tug. It lazed away, circling slowly, and he did not think it had seen them. He could not any longer see the place where they had landed, but he a.s.sumed that by now the yacht had looped back and come in--if not there somewhere close by. They could figure on nine to eleven men hunting them, depending on whether they left the ships guarded or not. Either way, it was too many.

"Listen," he said aloud to Shearing. "Listen, I want to ask you. What you said about latent impressions--you think I might have seen and heard the killer even though I was unconscious?"

"Especially heard. Possible. With your increased power, and ours, impressions received through sense-channels but not recognized at the time or remembered later might be recovered." He shook his head. "Don't bother me."

"I just wanted to know," said Hyrst. He thought of his son, and the two daughters he hoped he would never see. He thought of Elena. It was too late to do anything for her, but the others were still living. So was he, and he intended to stay that way, at least until he had done what he set out to do.

"Old Bellaver was behind that killing, wasn't he? Old Quentin, this one's grandfather."

"Yes. Don't bother me."

"One thing more. Do we Lazarites live longer than men?"

Shearing gave him a curious, brief look. "Yes."

The tug was out of sight behind a ma.s.sive rearing shape that seemed to clutch a broken ship between its paws. Symbolic, perhaps, of s.p.a.ce? Who knew? Hyrst led Shearing in wild impala-like leaps across an open s.p.a.ce, and into a narrow way that twisted, filled with darkness, among the bases of a group that resembled an outlandish procession following a king.

"How much longer?"

"Humane Penalty first came in a hundred and fourteen years ago, right?

After Seitz' method was perfected for saving s.p.a.cemen. I was one of the first they used it on."

"My G.o.d," said Hyrst. Yet, somehow, he was not as surprised as he might have been.

"I've aged," said Shearing apologetically. "I was only twenty-seven then."

They crouched, beside a humped shape like a gigantic lizard with a long tail. The tug swung overhead and slowly on.

Hyrst said, "Then it's possible the one who killed MacDonald is still alive?"

"Possible. Probable."

Hyrst bared his teeth, in what was not at all like a smile. "Good," he said. "That makes me happy."

They did not do any talking after that. They had had their helmet radios operating on practically no power at all, so that they couldn't be picked up outside a radius of a few yards, but even that might be too close, now that Bellaver's men had had time to get suited and fan out.

They shut them off entirely, communicating by yanks and nudges.

For what seemed to Hyrst like a very long time, but which was probably less than half an hour in measured minutes, they dodged from one patch of shadow to another, following an erratic course that Hyrst thought would lead them away from the ships. Once more the tug went over, slow, and then Hyrst didn't see it again. The idea that they might have given up occurred to him but he dismissed it as absurd. With the helmet mike shut off, the silence was beginning to get on his nerves. Once he looked up and saw a piece of cosmic debris smash into a monolith. Dust and splinters flew, and a great fragment broke off and fell slowly downward, b.u.mping and rebounding, and all of it as soundless as a dream. You couldn't hear yourself walk, you couldn't hear anything but the roar of your own breathing and the pounding of your own blood. The grotesque rocky avenues could hide an army, stealthy, creeping--

There was a hill, or at least a higher eminence, crowned with what might have been the cyclopean image of a man stretched out on a n.o.ble catafalque, with hooded giants standing by in att.i.tudes of mourning. It seemed like the best place to stop that Hyrst had seen, with plenty of cover and a view of the surrounding area. With luck, you might stay hidden there a long time. He jogged Shearing's elbow and pointed, and Shearing nodded. There was a wide, almost circular sweep of open rock around the base of the hill. Hyrst looked carefully for the tug. There was no sign of it. He tore out across the open, with Shearing at his heels.

The tug swooped over, going fast this time. It could not possibly have missed them. Shearing dropped the cloak with a grunt. "No use for that any more," he said. They bounded up the hillside and in among the mourning figures. The tug whipped around in a tight spiral and hung over the hill. Hyrst shook the sweat out of his eyes. His mind was clear again. The tug's skipper was babbling into his communicator, and in another place on the asteroid Hyrst could mentally see a thin skirmish line spread out, and in still another four men in a bunch. They all picked up and began to move, toward the hill.

Shearing said, nodding s.p.a.ceward, "Our friends are on the way. If we can hold out--"

"Fat chance," said Hyrst. "They're armed, and all we've got is flare-pistols." But he looked around. His eyes detected nothing but rock, hard sunlight, and deep shadow, but his mind saw that one of the black blots at the base of the main block, the catafalque, was more than a shadow. He slid into a crack that resembled a pa.s.sage, being rounded rather than ragged. Shearing was right behind him. "I don't like this,"

he said, "but I suppose there's no help for it."

The crack led down into a cave, or chamber, too irregularly shaped to be artificial, too smoothly surfaced and floored to be natural. There was nothing in it but a block of stone, nine feet or so long and about four feet wide by five feet high. It seemed to be a natural part of the floor, but Hyrst avoided it. On the opposite, the sunward side, there was a small windowlike aperture that admitted a ray of blinding radiance, sharply defined and doing nothing to illumine the dark on either side of it.
