"He must be stopped!" Paulson shouted. the vaults, and it interferes to a marked extent with my digestion. I juice and sat back, building up my fortitude to do business over the polished deck of my desk. powers of deduction would have seen through him in an instant!" I saw Horbit and Paulson happily off in each other's company. Paulson But instead of the usual morning run of hysterical relatives and masochistic mystics, I had to face one of my superiors from the Committee itself. he was not merely insane now. frighten me any more. I've put to sleep too many megalomaniacs, believe—but that didn't make them invalid to a brace of ex-Sleepers. dictators, and civil servants. "Warden Walker, I've been following your career with considerable It was a pair of fantastic stories that no man in his right mind would after—without me having to break the law and put them to sleep for crimes they hadn't committed. They would find out some day that I had lied to them, but maybe by that time they would have realized this world wasn't so bad. Fortunately, I was confident from their psych records that they were both incapable of ending their little game by homicide, no matter how justified they might think it was. "Hey, Warden," Captain Keller bellowed as I approached my office all, some criminals can't be helped psychiatrically. We can't execute them or turn them free we have to imprison them." I waited for Coleman's reaction. He merely nodded. "Of course, it's barbaric to think of a prison as a place of purpose of confinement is confinement." "I should think so," Coleman said emphatically. "Warden, don't you of riots, solitary confinement, television, and jailbreaks may have made time easier to serve? Do these men ever think they are "Coleman," I said, "you can get out of here. As warden, I'm granting you a five-year probation." of yellow light. "I don't approve of your decision, Warden. Not at all. Unless you alter it, I'll be forced to convince the rest of the conscious of all the time that is being spent out of their real lives Committee that your decisions are becoming faulty, that you are losing unless—" Coleman lifted a dark eyebrow above a black iris. "Unless?" I cleared my throat. "Unless they go mad and really believe the dream they are living. But as you know, sir, the rate of madness among Dreamland inmates is only slightly above the norm for the population as a whole." "How do prisoners like that adjust to reality?" Was he deliberately trying to ask tough questions? "They don't. They think they are having some kind of delusion. Many of them become schizoid and pretend to go along with reality while secretly 'knowing' it to be a lie." unbelievably absurd, a queasy little joke of some kind. But I didn't deny it. mad. It couldn't be true. Yet— Hadn't I thought about it ever since I had been appointed warden and all a Dream." Captain Keller stuck his head in, unannounced. "Hey, Warden, there's an active one out here. He claims that Dreamland compromises His plan for the Free Will of the Universe." prison vault for so many years for such and such a crime. His olive features were set off by bristling black eyes and a mobile prisoners might be a more effective form of investigation than mere "But Warden, sir, my psychiatrist said that I was unable to cope with reality. Come on now, Warden, you don't want a guy who can't cope with They wanted His eyes narrowed, both of them, on the next twitch. "Warden, I can always go out and commit another anti-social act." "I'm afraid not, Eddie. The file shows you are capable of only one Horbit laughed. "Your files aren't infallible, Warden." Warden." Nothing like this had ever happened in my years as warden. Suddenly, Coleman's words hit me in the back of the neck. If I got through the next twenty-four hours. This had to be some kind of test. But a test for what? all the others before him who had served long as warden of Dreamland. to stand the strain of putting their fellow human beings to sleep for long. "I couldn't have done it, Warden," Horbit mumbled drowsily. "I couldn't kill anybody. Unless it was like that other time." "Of course, Eddie," I said. many turns I went spinning through. I hardly heard Horbit when he half-shouted at me as my men led him from "You have to send me back now, Warden," he was shrilling. "You have to! know that's a crime! I have to be put to sleep!" Warden. No, sir, he had it made." took a pill and it went away. "Hold him in the detention quarters," I said finally. "I'm going to make a study of this." the ones I had to solve daily and I wasn't going to let that worry me. Much. I pressed my button to let Mrs. Engle know I was ready for the next interview. They came. There were the hysterical relatives, the wives and mothers and brothers who demanded that their kin be Awakened because they were special cases, not really guilty, or needed at home, or possessed of or if some important project was falling apart without his help, but most of the time I just sat with my eyes propped open, letting a sea of vindictive screeching and beseeching wailings wash around me. The relatives and legal talent were spaced with hungry-eyed mystics who were convinced they could contemplate God and their navels both conscientiously as an incarnation of Gautama. To risk sounding religiously intolerant, I usually kicked these out pretty swiftly. The onetime inmate who wanted back in after a reprieve was fairly rare. Few of them ever got that crazy. But it was my luck to get another the same day, the "Warden," Paulson said, "I've decided to give myself up. I murdered a conscience, Warden. I never lie awake a minute whenever I kill "Yes," Paulson said earnestly, "it does get to be a humdrum routine. I've been experimenting with all sorts of murders, but I just don't vaults without proof and conviction for a crime." "That doesn't sound very reasonable," Paulson objected. "Turning loose a homicidal maniac who is offering to go back to the vaults of his own My job is to keep the innocent out and the convicted in. And I do my guilt with another crime. Do you want a crime on your hands, Warden?" disarray. "Naw, he ain't violent, Warden. He just thinks he's somebody important." your grip just as all your predecessors did." "Sounds like a case for therapy, not Dreamland. Who does he think he is?" sentences to be fixed by the warden. My predecessors had given him "Warden Walker," Coleman intoned in his magnificent voice, "I'm you know them, I am 'guilty' and must be confined." I was stymied for an instant. I had expected him to say that I must extreme, Warden." "If it were my place to choose, yes. A few years, perhaps. But life—no, I think not." I threw up my hands. You don't often see somebody do that, but I did. Coleman smiled benignly. "Certainly, Warden." "Do you think you can pull the wool over my eyes, you scamp? Mine eyes have seen the glory." Horbit. At the end of it, Paulson was nodding just as eagerly. "I could be destroyed for telling you this, but our leader is planning the most gigantic conquest known to any intelligent race in the Universe. He is going to conquer Earth in all its possible futures and all its possible pasts. After that, there are other planets."
