The tug was out of sight behind a massive rearing shape that seemed to clutch a broken ship between its paws. Symbolic, perhaps, of space? Who knew? Hyrst led Shearing in wild impala-like leaps across an open space, 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 spacemen. I was one of the first they used it on." "My God," 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, 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.
