"Der screen is on," he chuckled. "Console each other, children. I am glad you came, Thorn Hardt. We watch der grand refiew of der Com-Pub fleet. Then I turn a little infention of mine upon you. It is a heat-ray of fery limited range. It will be my method of wooing der fair Sylva. When she sees you in torment, she kisses me sweetly for der prifilege of stopping der heat-ray. I count upon you, my friend, to plead with her to grant me der most extrafagant of concessions, when der heat-ray is searing der flesh from your bones. I feel that she is soft-hearted enough to oblige you. Yes?" He touched a button and the repaired television-screen lighted up. All the dome of mountains and sky was visible in it. There were dancing motes in sight, which were aircraft. "I haff remofed all metal-work from that side of der room," added Kreynborg comfortably, "so I can dare to turn my back. You cannot short der induction-screen again. That was clefer. But you face a scientist, Thorn Hardt. You haff lost." A sudden surge of flying craft appeared on the television screen. The grounded fleet of the United Nations was taking to the air again. In the narrow, two-mile strip between the two domes of force it swirled up and up.... Kreynborg frowned. "Now, what is der idea of that?" he demanded. He moved closer to the screen. The pocket-gun was left behind, five feet from his finger-tips. "Thorn Hardt, you will explain it!" "They hope," said Thorn grimly, "your fleet can make gaps in the dome to shoot through. If so, they'll go out through those gaps and fight." "Foolish!" said Kreynborg blandly. "Der only weapon we haff to use is der normal metabolism of der human system. Hunger!" * * * * * Thorn reached into his pocket. Kreynborg was regarding the screen absorbedly. Through the haze of flying dots which was the United Nations fleet, a darkening spot to westward became visible. It drew nearer and grew larger. It was dense. It was huge. It was deadly. It was the Com-Pub battle-fleet, nearly equal to the imprisoned ships in number. It swept up to view its helpless enemy. It came close, so every man could see their only possible antagonists rendered impotent. Such a maneuver was really necessary, when you think of it. The Com-Pub fleet had encountered one combat-squadron of the United Nations fleet, and that one squadron, dying, had carried down three times its number of enemies. It was necessary to show the Com-Pub personnel the rest of their enemies imprisoned, in order to hearten them for the butchery of civilians before them. Kreynborg guffawed as the Com-Pub fleet made its mocking circuit of the invisible dome. And Thorn raised his head. "Kreynborg!" he said grimly. "Look!" There was something in his tone which made Kreynborg turn. And Thorn held a little forked stick in his hand. "Turn off the induction-screen, or I kill you!" Kreynborg looked at him and chuckled.
