<passage>:
Despite his sudden irrational anger toward her, Maitland tried to stick your blood, the idea of going to Mars—just to go there and see what's there and walk under a new sky and a smaller Sun? Aren't you interested a member of the original atomic reaction-motor team, he possessed information that other military powers would very much like to obtain. Man . We are terribly interested in what can be done with people. Our scientists, like Swarts, are studying 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. any way, provided you cooperate. And you can forget the silly idea that we want your childish secrets about rocket motors." Maitland's heart jumped. "My reason for bringing you here is altogether different. I want to give you some psychological tests...." 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." After that outlandish cell, Swarts' laboratory looked rather "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 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 you'd lie down on this cot. I would like to test my apparatus." 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. Presently, a number of tiny electrodes were adhering to his temples and 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, 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 to go to the Moon. I'm interested in finding out why 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 contrary. Maitland frowned. This place certainly didn't have the Later, when that jewel of a planet had set and the stars were out, 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 psychological tests at their face value he had a chance to become a part of all that! He could spend his life among the planets, a citizen of deep space, a voyager of the challenging spaceways between the solar worlds. "I'm adaptable," he told himself gleefully. "I can learn fast. There'll be a job for me out there...." way of breaking down Swarts' reticence. He would have to make the man realize that secrecy wasn't necessary in this case. And if Swarts still wouldn't talk, he would have to find a way of forcing the issue. The fellow had said that he didn't need cooperation to get his results, shoulder, "You will have to ask Swarts about that. I cannot tell you." "Wait! You mean you don't know?" 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 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 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 "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 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.... "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. He forgot about it and went on whistling. He was picturing himself aboard a ship dropping in toward Mars, making planetfall at Syrtis Major "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 Century. And I wanted to talk with you, and he would not let me." She Believe me, I've been there, and what I've seen of this world looks a lot better." She shrugged. "Swarts says that I want to go back to the Dark Age of Technology because I have not adapted well to modern culture. Myself, I think I have just a romantic nature. Far times and places look more 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 Maitland wrinkled his brow. "Afrikander?" She frowned and shook her head. "What does that mean—space travel?" He was gripping the edge of the bed now, glaring at her. "A civilization that could discover time travel and build robot factories
