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, bumping 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 noble catafalque, with hooded giants standing by in attitudes 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 spaceward, "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 passage, 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
