Investigate the Ozark village of Granite City. "Just circle up the wagon train and see how the Indians fall," McCain said anxiously. a polygamy colony or a hideout for supposedly deported gangsters. I don't care much either. It's not my business. How could a whole town be filing false life and accident claims?" that concerned business was that the whole village of Granite City must be accident-prone. I rejected that one almost immediately. While an accident-prone was in himself a statistical anomaly, the idea of a whole town of them gathered together stretched the fabric of reality to the point where even an invisible re-weaver couldn't help it. There was an explanation for the recent rise in the accident rate down granite from Granite City was being put into use all over the planet Yet the rise in accident, compared to the rise in production, was out of all proportion. accident reports we had had from the village as far back as our records went. We had paid off on most of the claims since they seemed irrefutably for any kind of automobile accident from Granite City. I shut off the projector. It may be best to keep an open mind, but I have found in practice that Granite City had been in an organized conspiracy to defraud Manhattan-Universal and its predecessors of hundreds upon hundreds of thousands of dollars in false accident claims.

"You think the claims I've been filing for my people are false?" "The home office has some suspicions of that," I admitted. "I don't blame them, but they ain't. Look, the company gambles on luck, doesn't it?" "No. It works on percentages calculated from past experience." "But I mean it knows that there will be, say, a hundred fatal car "There's something to that. We call it probability, not luck." "Well, probability says that more accidents are going to occur in Granite City than anywhere else in the country, per capita." anything can happen but I don't—I can't—believe that in this town everybody has chanced to be an accident prone. Some other factor is operating. You are all deliberately faking these falls and fires—" "We're not," Thompson snapped. "Or else something is causing you to have this trouble. Maybe the "Whatever is going on, I'm going to find it out. I don't care what you do, but if I can find a greater risk here and prove it, the Commission will let us up our rates for this town. Probably beyond the capacity of these people, I'm afraid." "That would be a real tragedy, Mr. Madison. Insurance is vital to this town. Nobody could survive a year here without insurance. People pay me for their premiums before they pay their grocery bills." I shrugged, sorrier than I could let on. "I won't be able to pay for "That doesn't have anything to do with it.

Granite City exports some of the finest grade of the stone in different way of getting out every piece of stone." "It's too bad." "What's too bad?" "That you chose the wrong way so often," I said. getting the stone out. That's the way we like it. We don't want any outsider coming in and interfering with that." "If this quarry has anything to do with defrauding Manhattan-Universal, I can tell you that I will do something about that!" More and more, I was coming to believe that Granite City wasn't a job Crime is a structural flaw in a community, yes. But when the whole society is criminal, distorted, you can't isolate the flaw. The whole let him figure out why otherwise decent citizens felt secure in conspiracy to defraud an honored corporation. I didn't feel that I was licked or that the trip had been a failure. I had merely established to my intuitive satisfaction that the job was not in my field. "I can understand why you want to go somewhere where people are more trusting in that case." "They know the checks are good. It's me they refuse to trust to leave this place. They think they can't let me go." He has politely refused to let me use it. I'm a suspicious and undesirable character outfit behind the money box over there. He takes my letters but I never see him send them off. And I never get a reply." "Unfriendly of them," I said conservatively. "But how can they stop you from packing your dental floss and cutting out?" He's been the only one in or out of Granite City for five months." granite itself? How do they ship it out?" "It's an artificial demand product, like diamonds," Professor Parnell said. "They stockpile it and once a year the executive offices for the walking out?" me the big query: Why are the good people of Granite City doing this to "Look, I know the Klan is a growing organization but I can't go along with you." of Granite City have the most unusual deficency on record, I admit. Their psionic of a few recorded cases of supermen, but we have some, a trace. Granite City citizens have "I tell you they do," he said hoarsely. "We never realize it but we all have some power of precognition. If we didn't, we would have a hundred accidents a day—just as these people do . They can't foresee the bump in the road the way we can, or that that particular match will flare a little higher and burn their fingers. There are other things, as well.

To the people of Granite City that means ruining their only industry, putting them all out of work. They are used to this psionic sterility they don't see anything so bad about it. Besides, like everybody else, they have some doubts that there really are such things as telepathy and the rest to be affected." make of your story. This is something to be decided by somebody infallible—like the Pope or the President or Board Chairman of Manhattan-Universal. But the first thing to do is get you out of here. "Sorry," he said. "I should have been precognizant of that. I try to stay away from the rock as much as possible, but it's getting to me." I should have remembered something then. But, naturally, I didn't.
