"I'm not a spy! If I were a spy, then He was dangerously insane. He threatened to destroy everything that was noble and 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. you think waited for it. They simply knew that it had been captured by some other might see some advantage in attacking they ?" I shook my head, dumbfounded. "I can't answer a question like that," I said. "How do I know what they're thinking?" "They're human beings, aren't they?" he cried. "Like you? Like me? Like killed. She couldn't visualize anything less than that keeping me from arriving at the designated moment. When I told her what actually had happened—I'd broken a shoe lace—she refused to speak to me for four 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 not a spy, and I'm going to tell you what I am." I waited, looking as attentive as possible. all the other people in this mausoleum?" protect me." So I rehearsed my various approaches, realizing that when the time came I would probably be so tongue-tied I'd be capable of no more looking at me. She hadn't done that before, she'd merely gazed blankly at her screen and parroted her responses. But now she was actually looking at me . She nodded, wide-eyed. I had stumbled on a romantic, though I was too preoccupied to notice it at the time. "In every way but one," I continued. "She has one small imperfection, revealing a cleavage that I was too distraught at the moment to pay any attention to. "We're not supposed to give this information out, she leaned even closer to the screen—"there's a spy in the elevator." It was my turn to be stunned. I just gaped at her. "A—a what?" "A spy. He was discovered on the hundred forty-seventh floor, and outside at all. And when anyone tries to get into the shaft, he aims aims anybody who goes after him." told. A spy in the elevator! A spy who had managed to work his way all 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 return, occasional spies shot down as they tried to sneak into the building, occasional spies of our own leaving the Project in tiny be planning for us. Most spies didn't return merely lurking at the backs of our minds. After all, those external dangers had been no more than potential for decades, since what Dr. And the Treaty of Oslo. It seems there was a power-struggle between two sets of then-existing nations (they were something like Projects, only horizontal instead of vertical) and both sets were equipped with atomic weapons. The Treaty of Oslo began by stating that atomic war was unthinkable, and added that just in case anyone happened to think of it only atomic weapons could be used. No atomic weapons. (A tactical weapon is something you use on the soldiers, and a strategic weapons is Of course, they made up for this as best they could by using tactical world was quite dangerously radioactive. Except for the Projects. Or at least those of them which had in time installed the force screens which had been invented on the very eve of battle, and which deflected radioactive particles. However, what with all of the other treaties which were broken during on the horizon might be an ally. And then again it might not. Since But now there was a spy in the elevator. When I thought of how deeply he had penetrated our defenses, and of how many others there might be, still penetrating, I shuddered. The walls were our safeguards only so long as all potential enemies were on the other side of them. 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 except adventurous young boys playing cops and robbers, running up and didn't we? Usually, I mean, when they didn't contain spies. So what was time letters had been painted on it. The letters had long since flaked away, but they left a lighter residue of dust than that which covered the rest of the door. And so the words could still be read, if with difficulty. AUTHORIZED PERSONNEL I frowned, wondering immediately why this door wasn't being firmly guarded by at least a platoon of Army men. Half a dozen possible answers flashed through my mind. The more recent maps might simply 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 came face to face like that. We formed a brief tableau, both of us open-mouthed and wide-eyed. Unfortunately, he recovered first. I did exactly as I was told. I didn't move and I didn't make a sound. Which left me quite free to study him. high-cheekboned face featuring deepset eyes and a thin-lipped mouth. He wore gray slacks and shirt, with brown slippers on his feet. He looked exactly like a spy ... which is to say that he didn't look like a 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 "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 wrestling, judo and karati—talents I would prefer to disclose to him in my own fashion, when the time came. He was quiet for a moment. "What about radiation level on the Don't you people ever test them?" "To find out how far the radiation level outside has dropped." out for it."

He grinned bitterly, with one side of his mouth. "Of course. The damn fools! Spy! What do you suppose I'm going to spy on?" 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? military equipment? Your Army is supplied "The defenses," he interrupted me, "are non-existent. If you mean the adequate defense equipment. I chose to believe the Army over an enemy spy. "Your people send out spies, too, don't they?" he demanded. "Well, of course." "And what are they supposed to spy on?" "Well—" It was such a pointless question, it seemed silly to even answer it.
