THE SPY IN THE ELEVATOR By DONALD E. WESTLAKE not my job, you blatant idiot!" he shouted. "I'm not a spy! If I were a spy, then When the elevator didn't come, that just made the day perfect. A broken that would be my job!" He was dangerously insane. He threatened list. Suffice it to say that when the elevator didn't come, that put He glowered at me a moment longer, then shouted, "Bah!" and dropped place. "Ten o'clock," she'd said, smiling sweetly at me out of the "How do I know that?" he demanded. of course. She was an ore-sled dispatcher. Ore-sleds, being robots, waited for it. They simply knew that it had been captured by some other ?" shortly after we'd started dating, when I arrived at her place five minutes late and found her having hysterics. She thought I'd been said. "How do I know what they're thinking?" all the other people in this mausoleum?" And then the elevator didn't come. not a spy, and I'm going to tell you what I am." And that was like saying there's no need any longer for stomachs, but I didn't say so. I didn't say anything at all. "I'm a trained atomic engineer," he went on. "In my project, I worked on the reactor. Theoretically, I believed that there was a chance the radiation Outside was lessening by now, though we had no idea exactly malfunctioning air-cons, and I managed somehow to leave the apartment Linda lived down on the hundred fortieth floor, thirteen stories away. But then the elevator didn't come. The elevator had always arrived before, within thirty seconds of the button being pushed. This was a local stop, with an elevator that traveled between the hundred thirty-third floor and the hundred sixty-seventh floor, where it was possible to make connections for watch and it was three minutes to ten. Two minutes, and no elevator! If I vacillated, not knowing what to do next. Stay, hoping the elevator would come after all? Or hurry back to the apartment and call Linda, to Ten more seconds, and still no elevator. I chose the second alternative, raced back down the hall, and thumbed my way into my apartment. I dialed Linda's number, and the screen lit up with white Frantic, I dashed from the apartment again, back down the hall to the elevator, and leaned on that blasted button with all my weight. Even if the elevator should arrive right now, I would still be almost a minute was just too much. I went into a frenzy, and kicked the elevator door hurting the door. I limped back to the apartment, fuming, slammed the door behind me, grabbed the phone book and looked up the number of the Transit Staff. I dialed, prepared to register a complaint so loud they'd be able to hear me in sub-basement three. It took three tries before I got through to a hurried-looking female receptionist "My name is Rice!" I bellowed. "Edmund Rice! I live on the hundred and fifty-third floor! I just rang for the elevator and——" "The-elevator-is-disconnected." She said it very rapidly, as though she disconnected? Elevators don't disconnected!" I told her. "We-will-resume-service-as-soon-as-possible," she rattled. My bellowing the elevator is disconnected?" "I-am-sorry-sir-but-that——" what you people have done to me by disconnecting the elevator. You have , disconnecting the elevator? Not only won't she ?" I trembled with speechless fury. she leaned even closer to the screen—"there's a spy in the elevator." "A spy. He was discovered on the hundred forty-seventh floor, and managed to get into the elevator before the Army could catch him. He "Well—but why should there be any problem about getting him out?" "He plugged in the manual controls. We can't control the elevator from outside at all. And when anyone tries to get into the shaft, he aims the elevator at them." the elevator?" "He runs it up and down the shaft," she explained, "trying to crush told. A spy in the elevator! A spy who had managed to work his way all the way up to the hundred forty-seventh floor before being unmasked! But now there was a spy in the elevator. I dashed once more from the apartment and down the hall to the elevator, praying that the spy had been captured by now and that Linda would agree with me that a spy in the elevator was good and sufficient He was still there. At least, the elevator was still out. I sagged against the wall, thinking dismal thoughts. Then I noticed the door to the right of the elevator. Through that door was the stairway. I hadn't paid any attention to it before. No one ever uses the stairs down from landing to landing. I myself hadn't set foot on a flight of Actually, the whole idea of stairs was ridiculous. We had elevators, the use of stairs? And now, after all these years, the stairs might prove useful after all. It was only thirteen flights to Linda's floor. At sixteen steps a Could I descend two hundred and eight steps for my true love? I could. If the door would open. finally opened half way. I stepped through to the musty, dusty landing, took a deep breath, and started down. Eight steps and a landing, eight On the landing between one fifty and one forty-nine, there was a ELEVATOR SHAFT I frowned, wondering immediately why this door wasn't being firmly As I stood there, pondering these possibilities, the door opened and the spy came out, waving a gun. He couldn't have been anyone else but the spy. The gun, in the first elevator shaft. Looking back, I think he must have been just as startled as I when we exactly like a spy ... which is to say that he didn't my parents' apartment. at the descending stairs and whispered, "Where do they go?" "Good," he said—just as we both heard a sudden raucous squealing from perhaps four flights down, a squealing which could be nothing but the opening of a hall door. It was followed by the heavy thud of ascending said, "Where do you live?" the door. He stood close behind me, the gun pressed against my back, false move I'll kill you. Now, we're going to your apartment. We're We went. I have never in my life seen that long hall quite so empty as it was right then. No one came out of any of the apartments, no one emerged from any of the branch halls. We walked to my apartment. I thumbed the door open and we went inside. Once the door was closed behind us, he visibly relaxed, sagging against the door, his gun hand hanging limp at his side, a nervous smile As I made the chico, he asked me questions. My name first, and then, "What do you do for a living?" I thought fast. "I'm an ore-sled dispatcher," I said. That was a lie, "Of course not," I told him. I was on secure ground now, with Linda's before de-radiating them?" "To find out how far the radiation level outside has dropped." Incredible! I nearly poured boiling water all over myself. "Outside? Of before he ever made that first step from the cave?" took for him to turn around and go right back into the cave again." He as he talked. "Is this the life of man? It is not. Is this even a He asked the question so violently and urgently that I knew I had to answer quickly and well, or the maniac would return. "I—I wouldn't know, exactly," I stammered. "Military equipment, I suppose." "Military equipment? What a spy, then it follows that I'm doing the same thing, right?"
