Charley moved into place behind them, and came out blinking in the glare of the front platform. "Siamese twins," Dave was shouting. "A contemporary marvel of science, ladies and gentlemen--and here we have ..." Charley stepped forward as Ned and Ed stepped back into the shadows again. "... Charley de Milo! Ladies and gentlemen, the world-wide fame of this brave and talented boy is stupendous! His feats of skill will amaze you! Watch him thread a needle! Watch him comb his hair! And all for one thin quarter, ladies and gentlemen, only the fourth part--" The electronic band choked on Sousa, coughed and began again with Kabalevsky. Charley watched the audience below, staring up at him, hundreds of faces. He heard their gasp as he flexed his shoulders and turned. He grinned down, taking a second longer than usual, and then stepped back, still grinning. "Charley de Milo, the Armless Wonder!" Dave said. "And many more sights inside, ladies and gentlemen, sights to amaze you, sights to chill your very blood, sights ..." * * * * * One-thirty, and the last show over. The rocket had come down for the night; all over the midway lights were blinking off and silence was creeping, like a stain, over the ground. Professor Lightning was sitting on his bunk, in the small tent he shared with Erma the Fish Girl. Erma was out drinking with Dave Lungs and some of the others, and only the professor and Charley de Milo were in the room. Charley was sitting on Erma's bunk, looking resigned. "Well, if you still want to talk to me," he said, "now's your chance. O.K.?" "I certainly want to talk to you," Professor Lightning said firmly. "I want to tell you of the most important moment of your life." Charley tried to think of something to say to this, but there wasn't anything. He shifted on the bunk, scratched at his nose with his left foot, and grinned spastically. "Sure," he said at random. "And, by the way, I'm sorry about before, professor. But the show was going on, and--" "The show," Professor Lightning said, in tones of the utmost contempt. "Forget about the show--now, and tomorrow, and forever." "But--" "No words," Professor Lightning said, raising a hand delicately. "Please. Allow me to tell you of my invention." Charley sighed and lay back on the bed. "Invention, professor?" he said. "You mean sort of a machine?" For some reason, Professor Lightning looked irritated. "It's not a machine," he said flatly. Then he sighed and his tone changed. "Charley, my boy," he said, "do you remember what I was telling you before? About how the world has entered a new Age of Science? How new inventions, new discoveries, are coming along every day?" "Well, sure," Charley said. "The papers talk about it every once in a while. You know, I see the papers, or the Chicago _American_, anyhow. My mother sends it to me. She likes the columns."
