fellow-captive? Her suit was only a flimsy work-about model, as airtight as his but without the bracing required for building jet propulsors into it. It contained air reserves enough, and limited water; but neither food nor emergency medical supplies. McCray had both of these, of course. It was merely one more reason why he could not abandon her and go on ... if, that is, he could find some reason for going in one direction preferably to another, and if a wall would conveniently open again to let him go there. He could give her an injection of a stimulant, he mused. Would that improve the situation? Not basically, he decided, with some regret. Sleep was a need, not a luxury; it would not help her to be awakened chemically, when body was demonstrating its need for rest by refusing to wake to a call. Anyway, if she were not seriously injured she would undoubtedly wake of her own accord before long. He checked pulse and eye-pupils; everything normal, no evidence of bleeding or somatic shock. So much for that. At least he had made one simple decision on his own, he thought with grim humor. To that extent he had reestablished his mastery of his own fate, and it made him feel a touch better. Perhaps he could make some more. What about trying to find a way out of this place, for instance? It was highly probable that they would not be able to stay here indefinitely, that was the first fact to take into account. Either his imagination was jumpy, or the reek of halogens was a bit stronger. In any case there was no guarantee that this place would remain habitable any longer than the last, and he had to reckon with the knowledge that a spacesuit's air reserve was not infinite. These warrens might prove a death trap. McCray paused, leaning on the haft of his ax, wondering how much of that was reason and how much panic. He knew that he wanted, more than anything to get out of this place, to see sky and stars, to be where no skulking creatures behind false panels in the walls, or peering through televiewers concealed in the furnishings, could trick and trap him. But did he have any reason to believe that he would be better off somewhere else? Might it not be even that this place was a sort of vivarium maintained for his survival—that the leak of poison gases and heat in the first room was not a deliberate thrust at his safety, but a failure of the shielding that alone could keep him alive?
