Orphans of the Sky by Robert A. Heinlein

his desk top, and pursed his lips. "It makes a problem—your coming back like this. I'm afraid I can't just assign you to your old job; Mort Tyler has that. But we'll find a place for you, suitable to your rank."
           Hugh recalled Mort Tyler and not too favorably. A precious sort of a chap, always concerned with what was proper and according to regulations. So Tyler had actually made scientisthood, and was on Hugh's old job at the Converter. Well, it didn't matter. "That's all right," he began. "I wanted to talk to you about—"
           "Of course, there's the matter of seniority," Ertz went on. "Perhaps the council had better consider the matter. I don't know of a precedent. We've lost a number of scientists to the muties in the past, but you are the first to escape with his life in my memory."
           "That doesn't matter," Hugh broke in. "I've something much more pressing to talk about. While I was away I found out some amazing things, Bill, things that it is of paramount importance for you to know about. That's why I came straight to you. Listen, I—"
           Ertz was suddenly alert. "Of course you have! I must be slowing down. You must have had a marvelous opportunity to study the muties and scout out their territory. Come on, man, spill it! Give me your report."
           Hugh wet his lips. "It's not what you think," he said. "It's much more important than just a report on the muties, though it concerns them, too. In fact, we may have to change our whole policy with respect to the mu—"
           "Well, go ahead, go ahead! I'm listening."
           "All right." Hugh told him of his tremendous discovery as to the actual nature of the Ship, choosing his words carefully and trying very hard to be convincing. He dwelt lightly on the difficulties presented by an attempt to reorganize the Ship in accordance with the new concept and bore down heavily on the prestige and honor that would accrue to the man who led the effort.
           He watched Ertz's face as he talked. After the first start of complete surprise when Hugh launched his key idea, the fact that the Ship was actually a moving body in a great outside space, his face became impassive and Hugh could read nothing in it, except that he seemed to detect a keener interest when Hugh spoke of how Ertz was just the man for the job because of his leadership of the younger, more progressive scientists.
           When Hugh concluded, he waited for Ertz's response. Ertz said nothing at first, simply continued with his annoying habit of drumming on the top of his desk. Finally he said, "These are important matters, Hoyland, much too important to be dealt with casually. I must have time to chew it over."
           "Yes, certainly," Hugh agreed. "I wanted to add that I've made arrangements for safe passage up to no-weight. I can take you up and let you see for yourself."
           "No doubt that is best," Ertz replied. "Well—are you hungry?"
           "No."
           "Then we'll both sleep on it. You can use the compartment at the back of my office. I don't want you discussing this with anyone else until I've had time to think about it; it might cause unrest if it got out without proper preparation."
           "Yes, you're right."
           "Very well, then"—Ertz ushered him into a compartment behind his office which he very evidently used for a lounge—"have a good rest," he said, "and we'll talk later."
           "Thanks," Hugh acknowledged. "Good eating."  
           "Good eating."  
           Once he was alone, Hugh's excitement gradually dropped away from him, and he realized that he was fagged out and very sleepy. He stretched out on a built-in couch and fell asleep.
           When he awoke he discovered that the only door to the compartment was barred from the other side. Worse than that, his knife was gone.
           He had waited an indefinitely long time when he heard
