He threatened were my Project?" I stared at him. "That's impossible!" I cried. "We aren't planning to attack anybody! We just want to be left in peace!" "How do I know that?" he demanded. "It's the truth! What would we want to attack anybody for?" waited for it. They simply knew that it had been captured by some other said. "How do I know what they're thinking?" think I'm a spy. That blundering Army of yours thinks I'm a spy. That fathead who turned me in thinks I'm a spy. But I'm a spy, and I'm Romantic Approach: "Darling, I can't live without you at the moment.

I dialed, prepared to register a complaint so loud what you people have done to me by disconnecting the elevator. You have ruined my life." done , disconnecting the elevator? Not only won't she she leaned even closer to the screen—"there's a spy in the elevator." I just gaped at her. "A—a what?" "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 jammed it between floors. But the Army is doing everything it can think of to get him out." "Well—but why should there be any problem about getting him out?" outside at all. And when anyone tries to get into the shaft, he aims the elevator at them." That sounded impossible. "He "He runs it up and down the shaft," she explained, "trying to crush anybody who goes after him." afraid they'll have to starve him out." "Oh, no!" "We-will-resume-service-as-soon-as-possible." Click. Blank screen. For a minute or two, all I could do was sit and absorb what I'd been 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! that lax, the Project was doomed, force-screen or no. Who knew how many more spies there were in the Project, still unsuspected? Until that moment, the state of siege in which we all lived had had no reality for me. The Project, after all, was self-sufficient and completely enclosed. No one ever left, no one ever entered. Under our threat of other projects had never been more for me—or for most other people either, I suspected—than occasional ore-sleds that didn't return, occasional spies shot down as they tried to sneak into the building, occasional spies of our own leaving the Project in tiny radiation-proof cars, hoping to get safely within another project and bring back news of any immediate threats and dangers that project might be planning for us. Most spies didn't return within the Project life was full, the knowledge of external dangers merely lurking at the backs of our minds. After all, those external dangers had been no more than potential for decades, since what Dr. lived in Projects. From the very beginning, small attempts were made to make ore-sleds capable of seeking out raw materials unavailable within the Projects themselves and so on. And all because of, among other things, the population explosion. weapon is something you use on the soldiers, and a strategic weapons is was quite sure any more who was on whose side. That project over there on the horizon might be an ally. And then again it might not. Since they weren't sure either, it was risky to expose yourself in order to But now there was a spy in the elevator. When I thought of how deeply he had penetrated our defenses, and of how were our safeguards only so long as all potential enemies were on 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 I hadn't paid any attention to it before. No one ever uses the stairs except adventurous young boys playing cops and robbers, running up and down from landing to landing. I myself hadn't set foot on a flight of didn't we? Usually, I mean, when they didn't contain spies. So what was guarded by at least a platoon of Army men. Half a dozen possible shut on the other side. The Army might have caught the spy already. the spy came out, waving a gun. He couldn't have been anyone else but the spy. The gun, in the first open-mouthed and wide-eyed. high-cheekboned face featuring deepset eyes and a thin-lipped mouth. He exactly like a spy ... which is to say that he spy, he looked overpoweringly ordinary. More than anything else, he But if I had any visions of imminent rescue, the spy dashed them. He I knew my only slim chance of safety lay in answering his questions false move I'll kill you. Now, we're going to your apartment. We're friends, just strolling along together. You got that?" read my intentions on my face. He straightened, shaking his head. He said, "Don't try it. I don't want to kill you. I don't want to kill to sic your Army on me too soon, and I'll leave. If you don't try any silly heroics, nothing will happen to you." "You'll never get away," I told him. "The whole Project is alerted." "You let me worry about that," he said. He licked his lips. "You got And now I had yet another grudge against this blasted spy. Which than to me.

I decided that this man was doubly dangerous. Not only was he a spy, to watchful spy. suddenly said, "What did they tell you I was? A spy?" fools! Spy! What do you suppose I'm going to spy on?" spy.

"They're supposed to look for indications of an attack by one of the other projects." "And do they find any indications, ever?" "I'm sure I don't know," I told him frostily. "That would be classified spies are doing, and if a spy, then it follows that "I don't follow you," I admitted.
