<passage>:
were working on the cards at one end of the room, I would be moving around the other—checking the stock, packing the stuff for shipment, arranging it on the shelves, sweeping the floor. I was a regular model attention to me. And every time I got a look at his hand, I pushed the little button on but we got a steady advantage, day after day. We did so well we took on another man—I can take physical labor or leave it alone, and I leave it alone every chance I get. That was where we first felt the trouble. Our new boy was around twenty. He had a swept-wing haircut, complete with tail fins. Also he had a silly laugh. Now, there are jokes in a 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. 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 called him, "lay off. Never 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 have to. I'd express him myself—express him right out of our setup. manufacturer named Chapo a wheel, and he looked it. He was red-faced, 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. 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: "Eight big ones! Eight thousand bucks! And how you did it, I'll never know!" glasses, grinning. But he didn't grin back. He looked puzzled. He glanced toward the window. I looked too, and then I saw what he was puzzled about. It was pretty When I turned around to look for Skippy, to ask him some questions, he was gone. Evidently he didn't want to answer. I beat up and down every block in the neighborhood until I spotted him 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 through a drawn shade. 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 you're one I can't." "What kind of goofy talk is that?" I demanded. But, to tell you the truth, I didn't think it was so goofy. The window shade was a lot goofier. "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 mind, you ought to listen in on Henry's." He looked along the stools. But I didn't like Skippy's idea of proof. He offered to call off what "Black," Skippy said. I threw down fifty bucks. Black it was. That rattled me. When Skippy said black, I put the fifty on red. Black won it. "How come I played to lose?" I patted his shoulder. "Sonny, you got a lot to learn. Jake's is no fair game. This was only a dry run." 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." 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! Otherwise, you can understand, I might not want him around all the time. But this way I had my own personal bug in every game in town, and I didn't even have to spend for batteries. Card games, gaffed wheels, everything. Down at the track he could follow the smart-money guys around and let me know what they knew, which was plenty. We could even And think of the fringe benefits! With Skippy giving the women a 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. 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 and give him a little lesson about talking. 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 and he recognized me. But you don't make your TV set play better by kicking it. You don't help a fine Swiss watch by pounding it on an anvil. Skippy could walk 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!" 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 on another frequency. Make sense? I'm positive about it. He sticks to 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 get them. Like what he tells me about the people—I because I have to get Skippy back in business.
