THE NON-ELECTRONIC BUG Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] I wouldn't take five cents off a legitimate man, but if they want to gamble that's another story. What I am is a genius, and I give you a piece of advice: Do not ever degenerate card players around, I sometimes get a call. Not dice—I don't have a machine to handle them. But with cards I have a machine to force the advantage. hardware business, but business wasn't good and he was looking for a little extra cash on the side. It turns out that the other little wholesalers in the loft building where he has his business are all didn't want to be away and maybe miss it.... It never came but the card players did. attention to me. And every time I got a look at his hand, I pushed the little button on card game—somebody taking a beating will sound off, to take away some of the sting, but nobody laughs because the cracks are never funny. But they were to our new boy. He laughed not only when the mark made some crack, but a lot of the time when he didn't. It got so the customers were looking at him with a lot of dislike, and that was bad for business. So I called him out into the hall. "Skippy," I said—that's what we Never rub it in to a sucker. It's enough to take his money." He ran his fingers back along his hair. "Can't a fellow express himself?" I gave him a long, hard unhealthy look. Express himself? He wouldn't with hanging jowls and a big dollar cigar he announced that he only played for big stakes ... and, nodding toward the kid and me, that he didn't like an audience. Henry looked at us miserably. But what was he going to do? If he didn't go along, the word could spread that maybe there was something wrong going on. He had to play. "Take the day off, you two," he said, but he wasn't happy. I thought fast. Because we still had a chance. With the field glasses and Skippy's players, didn't know the score age, bifocals are standard equipment, but to judge from Skippy's fast, sure call of the cards, his eyesight was twenty-twenty or better. After about an hour, Skippy put down the glasses and broke the news: the game was over. time to clear out. Henry greeted us with eight fingers in the air. Eight hundred? But before I could ask him, he was already talking: "Eight big ones! Eight thousand bucks! And how you did it, I'll never know!" Well, eight thousand was good news, no doubt of that. I said, "That's the old system, Henry. But we couldn't have done it if you hadn't When I turned around to look for Skippy, to ask him some questions, he opened his mouth to say hello. I shook my head, but Skippy said, said, "You made a mistake, kid." "Running out?" He shrugged. "It's not the first mistake I made," he said bitterly. "Getting into your little setup with the bugged game came before that." I said, "You can always quit," but then stopped. Because it was a lie. He couldn't quit—not until I found out how he read Chapo's cards He said drearily, "You've all got me marked lousy, haven't you? Don't kid me about Henry—I know. I'm not so sure about you, but it wouldn't surprise me." "What are you talking about?" "I can hear every word that's on Henry's mind," he said somberly. "You, no. Some people I can hear, some I can't "All my life," said Skippy, "I've been hearing the voices. It doesn't matter if they talk out loud or not. Most people I can hear, even when The kid finished his coffee. "Well," he said, "you want to know what the counterman's got on his mind?" He leaned over and whispered to me. I yelled, "That's a lousy thing to say!" Everybody was looking at us. He said softly, "You see what it's like? I don't want to hear all this stuff! You think the counterman's got a bad "See that fat little woman down at the end? She's going to order another cheese Danish." counterman, and she got another cheese Danish. I thought it over. What he said about Henry holding out on me made it real serious. I had to have more proof. But I didn't like Skippy's idea of proof. He offered to call off what The wheel spun, but that didn't stop the betting. Jake's hungry. In his place you can still bet for a few seconds after the wheel starts turning. "Black," Skippy said. I threw down fifty bucks. Black it was. That rattled me. "Call again," I said. When Skippy said black, I put the fifty on red. Black won it. Then I got rid of him, because I had something to do. Henry came across. He even looked embarrassed. "I figured," he said, "uh, I figured that the expenses—" "Save it," I told him. "All I want is my split." He handed it over, but I kept my hand out, waiting. After a minute he a chance! It was going to be Skippy and me, all the way. Not only could he read minds, but the capper was that he couldn't read mine! And think of the fringe benefits! With Skippy giving the women a preliminary screening, I could save a lot of wasted time. At my age, time is nothing to be wasted. I could understand a lot about Skippy now—why he didn't like most people, why he laughed at jokes nobody else thought were funny, or even could hear. But everybody has got to like somebody, and I had the edge over most of the human race. He didn't know what I was thinking. And then, take away the voices in his head, and Skippy didn't have much left. He wasn't very smart. If he had half as much in the way of brains We were all set to make a big score together, so I went back to his rooming house where I'd told him to wait, to get going on the big time. However, Henry had more brains than Skippy. I hadn't told Henry who tipped me off, but it didn't take him long to work out. After all, I had told him I was going out to look for Skippy, and I came right back and called him for holding out. No, it didn't take much brains. All he had to do was come around to Skippy's place So when I walked in the door, Skippy was there, but he was out cold, with lumps on his forehead and a stupid grin on his face. I woke him up help a fine Swiss watch by pounding it on an anvil. Skippy could walk and talk all right, but something was missing. "The voices!" he yelled, sitting up on the edge of the bed. I got a quick attack of cold fear. "Skippy! What's the matter? Don't you hear them any more?" He looked at me in a panic. "Oh, I hear them all right. But they're all different now. I mean—it isn't English any more. In fact, it isn't any language at all!" Like I say, I'm a genius. Skippy wouldn't lie to me he's not smart enough. If he says he hears voices, he hears voices. Being a genius, my theory is that when Henry worked Skippy over, he jarred his tuning strips, or whatever it is, so now Skippy's receiving the same story, telling me about what he's hearing inside his head, and he's too stupid to make it all up. There are some parts of it I don't have all figured out yet, but I'll everybody knows there's only one. But I'll figure it out I have to, because I have to get Skippy back in business. I don't have to add to them by associating with
