The sun was bright, far too bright, and there were few shadows left. Yet Dane, stopping to drink sparingly from his canteen, could not lose that sense of eyes upon him, of being tracked. Rock apes? Cunning as those beasts were, it was against their nature to trail in utter silence, to be able to carry through a long-term project. Lion, perhaps? He noted that Nymani and Asaki took turns at rear guard today, and that each was alert. Yet, oddly enough, none of them mentioned the uneasiness they must all share. They had a dry climb, finding no mountain stream to renew their water supply. All being experienced in wilderness travel, they made a mouthful of liquid go a long way. When the party halted slightly before midday, canteens were still half full. "_Haugh!_" They jerked up, hands on weapons. A rock ape, its hideous body clearly seen here, capered, coughed, spat. Asaki fired from the hip and the thing screeched, clawed at its chest where the dark blood spewed out, and raced for them. Nymani cut the beast down and they waited tensely for the attack of the thing's tribe, which should have followed the abortive lunge on the part of their scout. But there was nothing--neither sound nor movement. What did follow froze them all momentarily. That mangled body began to move again, drew itself together, crawled toward them. Dane knew that it was impossible that the creature could live with such wounds. Yet the beast advanced, its head lolling on its hunched shoulders so that the eyes were turned blindly up to the full glare of the sun, while it crawled to reach the man it could not see. "Demon!" Nymani dropped his needler, shrank back against the rocks. As the thing advanced, before their eyes the impossible happened. Those gaping wounds closed, the head straightened on the almost invisible neck, the eyes glared once more with life, and slaver dripped from the swine snout. Jellico caught up the needler Nymani had dropped. With a coolness Dane envied, the captain shot. And for the second time the rock ape collapsed, torn to ribbons. Nymani screamed, and Dane tried to choke back his own cry of horrified protest. The dead thing put on life for the second time, crawled, got somehow to its feet, healed itself, and came on. Asaki, his face greenish-pale, stepped out stiffly as if each step he took was forced by torture. He had dropped his needler. Now he caught up a rock as large as his own head, raised it high with arms on which the muscles stood out like ropes. He hurled the stone, and Dane heard as well as saw the missile go home. The rock ape fell for the third time. When one of those taloned paws began to move again, Nymani broke. He ran, his screams echoing thinly in the air, as the thing lurched up, the gory mess of its head weaving about. If his feet would have obeyed him, Dane might have followed the Khatkan. As it was, he drew his ray and aimed it at that shambling thing. Tau struck up the barrel.
