<passage>:
Tr'en were an efficient people. All the preliminary reports had agreed efficient physical scientists of the Tr'en—and that would mean, in the ordinary course of events, an invitation to join the Comity of An invitation, the Comity was sure, which the Tr'en would not accept. Korvin stretched out on the cell's single bunk, a rigid affair which was hardly meant for comfort, and sighed. He'd had three days of isolation, with nothing to do but explore the resources of his own to the wonder and amazement of his Tr'en captors. He could do, as a matter of fact, precisely nothing. He wished quietly even a folder of tourist pictures. The Wonders of Tr'en, according to would at least have been other prisoners to talk to. But on Tr'en at the walls. The Tr'en were efficient his captors had left him with a full stock of food concentrates. But he was almightily bored, and about ready to tell anything to As he reached this dismal conclusion, the cell door opened. Korvin got The Tr'en was tall, and slightly green. Korvin didn't The Tr'en regarded him narrowly through catlike pupils. "You are It was a ritual, Korvin had learned. "You are of the Tr'en," he the door behind him. Korvin thought of jumping the Tr'en, but decided "What do you want with me?" Korvin said. The Tr'en speech—apparently most rigorously logical construction of its kind Korvin had ever come Korvin sighed. "What are you doing here, then?" he asked. As that was a general word in the Tr'en language, from, by peaceful and vocal means." Korvin filed it away for future reference. "Why did the Ruler not come to me?" Korvin asked. Korvin shrugged, sighed and smoothed back his hair. "I obey the But Korvin meant exactly what he'd said. He was going to obey the commands of the Ruler of the Tr'en—and remove the Tr'en threat from the rest of the galaxy forever. That, after all, was his job. contrast of the Tr'en themselves were figured in. Korvin wasn't attempting to escape. He wasn't pleading with the Ruler. The Tr'en liked to have everything clear. They were a logical race. The Ruler had started with Korvin's race, his name, his sex—if under four feet." He used the Tr'en measurement scale, of course it didn't seem necessary, though, to mention that both extremes of height usually less than that—approximately nine or ten inches. We call these children ," he volunteered helpfully. "Approximately?" the Ruler growled. "We ask for precision here," he Korvin nodded hurriedly. "Our race is more ... more approximate," he said apologetically. "Slipshod," the Ruler muttered. for you." "You will answer my questions," the Ruler said, "with exactitude." He match their enormous command of the physical universe adapting a The Tr'en, under other circumstances, would have been a valuable addition to the Comity of Nations. Korvin's appreciation of the size of that menace was growing hourly. him telling an untruth, he wasn't likely to live long, and his job—not to mention the strongest personal inclinations—demanded most pet, Korvin knew, something like a greatly magnified deathwatch beetle. adjusted satisfactorily to your physiology. The questioning will now continue." Korvin swallowed again. The test hadn't really seemed extensive enough to him. But, after all, the Tr'en knew their business, better than The Ruler was frowning at him. Korvin did his best to look receptive. Korvin looked sober. "Yes," he said. mean exactly that. As nearly as Korvin could make out, it meant "disposed of for all time." "No," he said. "What else does your job entail?" the Ruler said. The Ruler roared. "Do not waste time with the obvious!" he shouted. "Do not try to trick us we are a logical and scientific race! Answer correctly." Korvin shrugged. "I replied to your question," he said. "I did not "I—" The Ruler stopped himself in mid-roar. "You try to confuse the Ruler," he said at last, in an approximation of his usual one. "But the Ruler will not be confused. We have experts in matters of logic"—the Tr'en word seemed to mean right-saying Korvin's guards were standing around doing nothing of importance now The Ruler looked down at Korvin. "You will find that you cannot trick us," he said. "You will find that such fiddling"— chulad-like Korvin The experts in logic arrived shortly, and in no uncertain terms Korvin the tortoise, and all the other lovely paradox-models scattered around were so much primer material for the Tr'en. "They can be treated The expert frowned horribly, showing all of his teeth. Korvin did his call this a good thing. You can mean only that your plan is different from the one we are occupied with." "It has no name," Korvin said truthfully. The Tr'en idiom was like the A short silence was broken by one of the attendant experts. "We have theorized that an underling may be permitted to make some of his own decisions, leaving only the more extensive ones for the master. This the logical Tr'en had determined to begin from the beginning, instead Korvin shrugged. "The explanation cannot be given to you." "Then you will suffer unpleasant consequences if you describe it to us?" the Ruler went on. "I will not," Korvin said. It was the signal for another conference. With some satisfaction, Korvin noticed that the Tr'en were becoming slightly puzzled The plan was taking hold. The Ruler had finished his conference. "You are attempting again to confuse us," he said. Korvin shook his head earnestly. "I am attempting," he said, "not to confuse you." "Then I ask for an answer," the Ruler said. The Ruler hesitated, then nodded. "Ask it," he said. "We shall answer it if we see fit to do so." from a knot of Tr'en, inclined his head in Korvin's direction, and began. "Our government is the only logical form of government," he said in a high, sweet tenor. "The Ruler orders all, and his subjects obey. In this way uniformity is gained, and this uniformity aids in the speed of possible action and in the weight of action. All Tr'en act instantly in the same manner. The Ruler is adopted by the previous Ruler in this way we are assured of a common wisdom and a steady judgment." Korvin nodded. "Yes." accept them." "Do you act against your own interests?" Korvin shrugged. "Not knowingly," he said. The Ruler flashed a look at the technicians handling the lie-detector. Korvin turned to see their said. "It is a defect in your explanation," the Ruler almost snarled. "My explanation is as exact as it can be," he said. The Ruler breathed gustily. "Let us try something else," he said. Korvin wondered, as the technicians argued, how long they'd take to correct. He hoped it wasn't going to be too long he could foresee another stretch of boredom coming. And, besides, he was getting homesick. Korvin found himself the object of more attention than he had hoped method of resolving the obvious contradictions in his statements. Some of them went away fuming. Others simply went away, puzzled. insoluble. And the Tr'en weren't capable of that sort of Korvin thanked his lucky stars that their genius had been restricted particular plan. That, and the political structure of the Tr'en. The same lack of insight let the Tr'en subconscious work on his messages, but he could send them. He sent one now. Mission accomplished the Tr'en aren't about to come marauding out into space too soon. They've been given food for thought—nice indigestible food that's going to stick in their craws until they finally manage to digest it. But they can't digest it and stay what they are you've got to be
