There was a thump. Maitland stirred, came half awake, and opened his Despite his sudden irrational anger toward her, Maitland tried to stick What had he heard? He had a definite impression that the sound had come Something moved in the darkness on the other side of the room. Maitland Shock contracted Maitland's diaphragm and spread through his body. Where was he? Who had brought him here? For what purpose? what ?" She smiled. "In a room downstairs there is the head of a lion. Swarts . We are terribly interested in what can be done with people. Our scientists, like Swarts, are studying the door slid aside and disappeared. Maitland glanced in at Maitland stared at her, his face blank. His mind had just manufactured Maitland looked up at the girl, who was regarding him silently with sandals, stood across the threshold looking in at him. Maitland stood Somehow, the face didn't go with the rest of him. The man had the head of a thinker, the body of a trained athlete—an unusual combination. Impassively, the man said, "My name is Swarts. You want to know where you are. I am not going to tell you." He had an accent, European, but otherwise unidentifiable. Possibly German. Maitland opened his mouth to protest, but Swarts went on, "However, you're free to do all the guessing you want." Still there was no suggestion of a smile. seems to me that you could have found someone less conspicuous to give your tests to." Briefly, then, Swarts did smile. "They won't find you," he said. "Now, come with me." "Lie down," Swarts said. When Maitland hesitated, Swarts added, "Understand one thing—the more you cooperate, the easier things will be for you. If necessary, I will use coercion. I can get all my results me." "What's the idea?" Maitland asked. "What is all this?" Swarts hesitated, though not, Maitland astonishedly felt, to evade an answer, but to find the proper words. "You can think of it as a lie detector. These instruments will record your reactions to the tests I Maitland stood there for a moment, deliberately relaxing his tensed muscles. "Make me." If Swarts was irritated, he didn't show it. "That was the first test," he said. "Let me put it another way. I would appreciate it a lot if Maitland shook his head stubbornly. "I see," Swarts said. "You want to find out what you're up against." He moved so fast that Maitland couldn't block the blow. It was to the solar plexus, just hard enough to double him up, fighting for breath. his chest, hips, knees, ankles, and arms, and Swarts was tightening a clamp that held his head immovable. clamped to the frame of the cot. Another cable left the box and joined the others. So—Maitland thought—Swarts could record changes in his skin potential, heartbeat, and blood pressure: the involuntary responses of the body to stimuli. The question was, what were the stimuli to be? "Your name," said Swarts, "is Robert Lee Maitland. You are thirty-four years old. You are an engineer, specialty heat transfer, particularly as applied to rocket motors.... No, Mr. Maitland, I'm not going to "You seem to know everything about me," Maitland said defiantly, Something eager leaped in Maitland's breast at the abrupt question, and he tried to turn his head. Then he forced himself to relax. "What do you mean?" Swarts was chuckling. "I really hit a semantic push-button there, didn't I? Maitland, I brought you here because you're a man who wants expectancy. Maitland sighed and said, "Hello," then glanced down could formulate any plan or policy. Where was he? Who was Swarts? What was the purpose of the "tests" he was being given? It was possible, of course, that this was all an elaborate scheme for getting military secrets, despite Swarts' protestations to the Maitland felt his worry drain away, leaving an almost mystical sense of he lay on the bed, still warm with excitement and relief. He didn't have to worry any more about military secrets, or who Swarts was. Those questions were irrelevant now. And now he could accept the After a while Maitland smiled to himself and went back to bed. shoulder, "You will have to ask Swarts about that. I cannot tell you." "Wait! You mean you don't know?" She shook her head. "I cannot tell you." we'll let it go at that." She grinned at him again as the door slid shut. Swarts came half an hour later, and Maitland began his planned offensive. "What year is this?" Swarts' steely eyes locked with his. "You know what the date is," he stated. "No, I don't. Not since yesterday." "Come on," Swarts said patiently, "let's get going. We have a lot to get through this morning." "I Wordlessly, Maitland climbed to his feet, preceded Swarts to the laboratory, lay down and allowed him to fasten the straps and attach the instruments, making no resistance at all. When Swarts started saying a list of words—doubtlessly some sort of semantic reaction test—Maitland began the job of integrating "csc x dx" in his head. It was a calculation which required great concentration and frequent tracing back of steps. After several minutes, he noticed that Swarts had stopped calling words. He opened his eyes to find the other man standing over him, looking somewhat exasperated and a little baffled. "What year is this?" Maitland asked in a conversational tone. "We'll try another series of tests." It took Swarts nearly twenty minutes to set up the new apparatus. He lowered a bulky affair with two cylindrical tubes like the twin stacks He inserted button earphones into Maitland's ears— Maitland gritted his teeth and fought to use his brain Swarts in standing by his silly rules and not telling him about this new world. Within a minute, he was in an ungovernable rage. His muscles tightened against the restraining straps. He panted, sweat came out on his forehead, and he began to curse. Swarts! How he hated.... There was blood hammering in Maitland's temples. His face felt hot and eyes and Swarts was standing over him, white-lipped. Maitland swore at him for a few seconds, then relaxed and smiled weakly. His head was starting to ache from the effort of blinking. "What year is this?" he asked. "All right," Swarts said. "A.D. 2634." Maitland's smile became a grin. "I really haven't the time to waste talking irrelevancies," Swarts said a while later. "Honestly. Maitland, I'm working against a time limit. "Ching?" "Ingrid Ching is the girl who has been bringing you your meals." Maitland considered a moment, then nodded. Swarts lowered the projector to his eyes again, and this time the engineer did not resist. "I think you are wonderful," she laughed. "You get everything you want, even from Swarts, and I have not been able to get even a little of what I want from him. I want to travel in time, go back to your 20th history since 1950. Five hundred years ago, Europe was overrun by Pan-Orientals. Today you could not find anywhere a 'pure' European or Asiatic." She giggled. "Swarts' ancestors from your time must be cursing in their graves. His family is Afrikander all the way back, but one of his great-grandfathers was pure-blooded Bantu. His full name is Maitland wrinkled his brow. "Afrikander?" After several seconds, Maitland swallowed. Something seemed to be the
