A moment later the metallic glass screen attached to the apparatus glowed with a white light and before the eyes of the astonished gathering there appeared, in reduced form, but plainly and clearly, the images of the performers in a room several hundred feet away. Just as on a moving picture screen, only not as large, but beautifully colored and clearer than ever moving pictures had been, the images of Mary, Helen, Mr. Damon and Ned were observed. They smiled, gestured and went through various motions, not one of which was obscured and not one but synchronized exactly with the words they used. “That’s my invention,” said Tom Swift simply. “If you think it is a success we can complete the deal.” “I guess there’s no question of it,” said Mr. X. “I, for one, am satisfied and as soon as——” He ceased speaking, for suddenly, in the midst of a song by the performers in the studio, the voices died away and the images faded from the screen. “Don’t cut it off!” begged Mr. B. “I was just beginning to enjoy it.” “I didn’t cut it off!” Tom answered quickly. “There’s something wrong!” Then, from the corridor without, the voice of Koku was heard crying: “I cotch him! I got him! Now I make him like jelly!” Like an echo came a frightened voice begging: “Let me go! Oh, let me go!” “Greenbaum!” shouted Tom, springing to the door in time to see the giant holding the plotting man in a grasp that made him helpless. “I cotch him!” cried Koku. “I be on watch out here like Mr. Tom always tell me. I see him sneak along and cut wire. He have big ball in his hand, too, but I knock it down. Over there in corner!” Garret Jackson made a jump for the corner indicated and picked up something which made him utter an exclamation of dismay. “It’s a bomb!” the superintendent shouted. There was a pail of water near by and into that the infernal machine was dropped just in time, for the fuse was spluttering and burning down. Greenbaum, choked into senselessness by Koku’s powerful grip, sank to the floor. Tom turned to the assembled moving picture and theater men. There was an implied accusation in his glance. “I hope you will believe us when I say we had absolutely nothing to do with this,” said Mr. X. “We have not seen Greenbaum since his former unauthorized attack on you. This is a terrible surprise to us.” “And to me, also,” said Tom. “I don’t know what damage he has done, but——” “He not do much!” chuckled Koku. “Me cotch him in time.” And so it proved. Greenbaum had managed to sneak into the laboratory because vigilance was somewhat relaxed, now that all danger seemed over. He had cut one of the electrical wires that carried power to Tom’s machine, hoping, in the confusion he knew would follow, to be able to plant his infernal machine and get away. But the giant was too quick for him. “Is the machine ruined?” asked Ned, coming from the broadcasting studio, followed by the other performers.
