He didn't know, and in the nature of things could not. But paradoxically the thought that escape might increase his danger made him all the more anxious to escape. He wanted to know. If death was waiting for him outside his chamber, McCray wanted to face it—now—while he was still in good physical shape. While he was still sane. For there was a limit to how many phenomena he could store away in the back of his mind; sooner or later the contradictions, the puzzles, the fears would have to be faced. Yet what could he do with the woman? Conceivably he could carry her; but could he also carry her suit? He did not dare take her without it. It would be no kindness to plunge her into another atmosphere of poison, and watch her die because he had taken her from her only hope of safety. Yet the suit weighed at least fifty pounds. His own was slightly more; the girl, say, a hundred and thirty. It added up to more mass than he could handle, at least for more than a few dozen yards. The speaker in his helmet said suddenly: "Herrell McCray, this is Jodrell Bank. Your transmission received. We are vectoring and ranging your signal. Stand by. We will call again in ten minutes." And, in a different tone: "God help you, Mac. What the devil happened to you?" It was a good question. McCray swore uselessly because he didn't know the answer. He took wry pleasure in imagining what was going on aboard Jodrell Bank at that moment. At least not all the bewilderment was his own. They would be utterly baffled. As far as they were concerned, their navigator had been on the bridge at one moment and the next moment gone, tracelessly. That in itself was a major puzzle; the only way off an FTL ship in flight was in the direction called "suicide." That would have been their assumption, all right, as soon as they realized he was gone and checked the ship to make sure he was not for some reason wandering about in a cargo hold or unconscious in a closet after some hard-to-imagine attack from another crewman. They would have thought that somehow, crazily, he had got into a suit—there was the suit—and jumped out of a lock. But there would have been no question of going back to look for him. True, they could have tracked his subspace radio if he had used it. But what would have been the good of that? The first question, an all but unanswerable one, would be how long ago he had jumped. Even if they knew that, Jodrell Bank, making more than five hundred times light-speed, could not be stopped in fewer than a dozen light-years. They could hardly hope to
