NO SUBSTITUTIONS By JIM HARMON Illustrated by JOHNSON take that ... but what if he was happening to it? Putting people painlessly to sleep is really a depressing job. It longer hopeless in his quest to gain another reality because he knew "Warden Walker, I've been following your career with considerable They wanted after—without me having to break the law and put them to sleep for nobody could last that long in my job. At least, none had yet. 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 time they would have realized this world wasn't so bad. sleepy-bye vaults? He's still sitting in there on your furniture as "Of course, it's barbaric to think of a prison as a place of I stretched out my wet palm toward the door. Was or was not Coleman telling the truth when he said this life of mine was itself only a Dream? If it was, did I want to finish my last day purpose of confinement is confinement." with the right decision so I could return to some alien reality? Or did is the most humane confinement possible?" "Well," I hedged, "it's the most humane we've found yet. I suppose Now was the time. "I should think so," Coleman said emphatically. "Warden, don't you He smiled at me briefly in supreme confidence. I changed my decision then, in that moment. And, in the next, changed it back to my original choice. "Coleman," I said, "you can get out of here. As warden, I'm granting He was unwrinkled, unperspiring, his eyes and mustache crisp as ever. 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 Committee that your decisions are becoming faulty, that you are losing your grip just as all your predecessors did." "Tell me, Councilman, what happened to the offer to release me from "How do prisoners like that adjust to reality?" "Yes, sir," I replied. "By letting the prisoner project his own I sat there and took it. He was telling me He didn't say anything. I didn't think he had to. "You wanted to make sure I made a painfully scrupulous decision in Hadn't I thought about it ever since I had been appointed warden and Captain Keller stuck his head in, unannounced. "Hey, Warden, there's an prison vault for so many years for such and such a crime. a prisoner what the modern penal system was all about by giving him a "Yes, indeed," Coleman concurred. Just that and no more. preposterous announcement he had made. "I'll see you tomorrow at this time then, Walker." The councilman be released from my Dream, he had said smugly. "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 Horbit couldn't accept history that he had no more life to live. He His eyes narrowed, both of them, on the next twitch. "Warden, I can Horbit laughed. "Your files aren't infallible, Warden." No, not his own flesh. Pseudo-flesh. He took out the gun that was underneath. "The beamer is made of X-ray-transparent plastic, Warden, but it works "I'm going to make you go down to the vaults and put me back to sleep, Warden." Nothing like this had ever happened in my years as warden. Horbit's screams brought in the guards. all the others before him who had served long as warden of Dreamland. A few had quit while they were still ahead and spent the rest of their lives recuperating. Our society didn't produce individuals tough enough to stand the strain of putting their fellow human beings to sleep for long. One of Keller's men had stabbed Horbit's arm with a hypospray to "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. I had banked on that, hadn't I, when I made my move? the bonds of muscle and narcotic that held him. "You have to send me back now, Warden," he was shrilling. "You have to! I tried to coerce you with a gun. That's a crime, Warden—you know that's a crime! I have to be put to sleep!" that makes him eligible. He couldn't lose, 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 such awesome talents and qualities as to be exempt from the laws of lesser men. Once in a while I granted a parole for a prisoner to see a dying mother 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. Paulson was a tall, lean man with sad eyes. The clock above his sharp shoulder bone said five till noon. I didn't expect him to take much out of my lunch hour. "Warden," Paulson said, "I've decided to give myself up. I murdered a blind beggar the other night." "For his pencils?" I asked. I examined the projection of his file. He was an embezzler, not a violent man. He had served his time and been released. Conceivably he never again placed in his path. He would not commit a crime of violence. Paulson tried his insufficient best to smile evilly. "It wasn't conscience, Warden. I never lie awake a minute whenever I kill you really were a murderer. But I can't send you back to the sleep a homicidal maniac who is offering to go back to the vaults of his own guilt with another crime. Do you want a crime on your hands, Warden?" I watched him out of the office and rang for lunch. The news on the wall video was dull as usual. A man got tired of hearing peace, safety, prosperity and brotherly love all the time. I "Naw, he ain't violent, Warden. He just thinks he's somebody important." "Councilman Coleman." I whistled. "What did they nail him on?" "Misuse of authority." over the bombshell Coleman had tossed in my lap in the morning, but now from the Committee. His job was so hypersensitive that if every transgression earned dismissal, no one could hold the position more Coleman had first received a suspended sentence, then two terminal sentences to be fixed by the warden. My predecessors had given him me out of executing this sentence by what you told me this morning?" only a Dream such as I imposed on my own prisoners could help him, I couldn't see. "Warden Walker," Coleman intoned in his magnificent voice, "I'm shocked. I pardon him despite the misguided rulings of the courts. Then I thought extreme, Warden." in the real world, but I had thought somehow he wanted to escape to a There seemed to be no point or profit in what he had told me that morning, nothing in it for him. Unless— Unless what he said was literally true. Coleman smiled benignly. "Certainly, Warden." a book tape on the Civil War when I found him. The tic in his cheek marked time with every new page. "President Lincoln," I said reverently. long, thin legs stretched out in front of him, staring dismally into the gloom of the room. No wonder he found reality so boring and depressing with so downbeat a mood cycle. I wondered why they hadn't been able to do something about adjusting his metabolism.
