of vision, he could sense another man and several machines. In front of him stood Fred Kemmer with an expression of satisfaction on his face. "Don't start thinking you're smart," Kemmer said. "You're in no position for it." "You've tried to kill me three times," Albert reminded him. "There's always a fourth time." "I don't think so. Too many people know." "Precisely my own conclusion," Kemmer said, "but there are other ways. Brainwashing's a good one." "That's illegal!" Albert protested. "Besides—" "So what?" Kemmer cut him off. "It's an illegal universe." Albert probed urgently at the IC man's mind, hoping to find something he could turn to his advantage, but all he found were surface thoughts—satisfaction at having gotten the spy where he could do no harm, plans for turning Albert into a mindless idiot, thoughts of extracting information—all of which had an air of certainty that was unnerving. Albert had badly underestimated him. It was high time to leave here, if he could. Albert visualized an area outside Vaornia, and, as he tried to push, a machine hummed loudly behind him. He didn't move. Mistake, Albert thought worriedly, I'm not going anywhere—and he knows I'm scared. "It won't do you any good," Kemmer said. "It didn't take too much brains to figure you were using hyperspace in those disappearing acts. There's an insulating field around that chair that'd stop a space yacht." He leaned forward. "Now—what are your contacts, and who gave you the information on where to look?" Albert saw no reason to hide it, but there was no sense in revealing anything. The Patrol had word of his arrest by now and should be here any moment. It was as though Kemmer had read his mind. "Don't count on being rescued. I stopped the Patrol report." Kemmer paused, obviously enjoying the expression on Albert's face. "You know," he went on, "there's a peculiar fact about nerves that maybe you don't know. A stimulus sets up a brief neural volley lasting about a hundredth of a second. Following that comes a period of refractivity lasting perhaps a tenth of that time while the nerve repolarizes, and then, immediately after repolarization, there
