As he squirmed and wriggled into the lock, they were already careening into the orange tube through the red swirling clouds. There was no longer any air. Choking, he managed with numbed fingers to screw his helmet on. Then, closing the lock, he proceeded into the ship. Nona was guarding her prisoner vigilantly. Miro sat there, sullen, defiant. Her glad, welcoming cry filled Grant with a new strange warmth. "I was so afraid for you when the ship started and you didn't show up," she said, "but I didn't dare leave him alone." She indicated Miro. "Good girl," he said admiringly. "We'll bind him now and then I want to show you something." * * * * * They stood a little later at the bow quartz port-hole. Down the long shaft through which they had risen they saw the glaring flame of the Gorm. As they looked, its regular pulsations turned irregular: it leaped and splashed as though it was a stormy, choppy sea. Then it gave one final mighty heave, and the universe seemed to shatter beneath them. The "walls" of the shaft collapsed about them and they were enswathed in a raging storm of red clouds. Nona turned to Grant. "Now, will you explain?" "Certainly," he grinned boyishly. "I simply reversed the switch that changes the current of the Gorm. I knew that it would then repel the liner out into space, as Miro was incautious enough to inform me. "Then I figured that if instead of direct current, an alternating flow could be induced, so as to attract and repel in quick succession, enough of a disturbance would be raised in that highly unstable mixture to start fireworks. So I rigged up an automatic break in the circuit, timed it to permit us to get up enough speed from the repulsion to be safely on our way before it would start. The circuit-breaker worked and the alternating current did the rest. That island is wiped out, and so is the Gorm. There'll be no further threat of danger to the solar system from that." "And Miro, what are we going to do with him?" "Turn him over to the Service. They'll take care of him. And now, young lady, if you have no further questions, shall I say it again?" She smiled up at him tenderly, answering: "If you wish." * * * * *
