Well, of course, after working as an ore-sled dispatcher for three 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 days. Until then, I'd managed somehow to keep the day's minor disasters from straight down to slag—I kept going over and over my prepared proposal speeches, trying to select the most effective one. violence that was so obviously in this lunatic. "The radiation level," he went on, "is way down. It's practically as low as it was before the Atom War. I don't know how long it's been that low, but I would guess about ten years, at the very least." He least a year or two, and I can't think of anyone I would rather spend both had been genetically desirable (neither of us were) I knew that Linda relished her freedom and independence too much to ever contract for any kind of marriage other than Non-P—Non-Permanent, No Progeny. 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 than a blurted, "Will you marry me?" and I struggled with zippers and malfunctioning air-cons, and I managed somehow to leave the apartment how much radiation had been released by the Atom War. But I wanted to test the theory, and the Commission wouldn't let me. They claimed public safety, but I knew better. If the Outside were safe and the that traveled between the hundred thirty-third floor and the hundred sixty-seventh floor, where it was possible to make connections for I would have been in a howling rage anyway, but this impossibility piled on top of all the other annoyances and breakdowns of the day three times before I realized I was hurting myself more than I was hundred and fifty-third floor!

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, marry me, she won't even speak to me! Not now! Not after this!" 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, had to ruin things for you this way.

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 be planning for us. Most spies didn't return old—had private names for every major war of the twentieth century. There was the Ignoble Nobleman's War, the Racial Non-Racial War, and World Wars One, Two, and Three. The rise of the Projects, according to Dr. Kilbillie, was the result of many many factors, but two of the most important were the population explosion and the Treaty of Oslo. The population explosion, of course, meant that there was continuously more and more people but never any more space. So that housing, in the historically short time of one Projects themselves and so on. And all because of, among other things, the population explosion. 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 tactical atomic weapons could be used. No atomic weapons. (A tactical weapon is something you use on the soldiers, and a strategic weapons is something you use on the folks at home.) Oddly enough, when somebody did think of the war, both sides adhered to the Treaty of Oslo, which meant that no Projects were bombed. Of course, they made up for this as best they could by using tactical atomic weapons all over the place. After the war almost the whole world was quite dangerously radioactive. Except for the Projects. Or at least those of them which had in time installed the force screens radioactive particles. However, what with all of the other treaties which were broken during the Ungentlemanly Gentleman's War, by the time it was finished nobody was quite sure any more who was on whose side. That project over there And so life went on, with little to remind us of the dangers lurking was left to the Army.

"Just enough for two And now I had yet another grudge against this blasted spy. Which "When they come back," he said. "How much radiation do they pick up? Don't you people ever test them?" "Of course not," I told him. I was on secure ground now, with Linda's information to guide me. "All radiation is cleared from the sleds and their cargo before they're brought into the building." "The same thing," he grumbled, "over and over again. Always the same of the caves? The long slow painful creep of progress, for millennia, with uniforms, whistles and hand guns, and that's about it." "The defenses," he interrupted me, "are non-existent. If you mean the other defenses are there? None." "If you say so," I replied stiffly. The Army claimed that we had they
