Craven grinned wryly. "You're right, but we can get along. The accumulators are practically drained, though, and we won't be able to store anything. Would you mind shooting us over just a little power? Enough to charge the accumulators a little for emergency use." He looked over his shoulder, almost apprehensively. "There might be an emergency out here, you know. Nobody knows anything about this place." "I'll give you a little power," Greg agreed. "Thank you very much," said Craven, half in mockery. "No doubt you think yourself quite smart, Manning, getting us out here. You know you have us stranded, that we can't collect more than enough power to live on." "That's why I did it," Greg said, and vanished. _CHAPTER NINETEEN_ Craven watched the _Invincible_ gather speed and tear swiftly through the black, saw it grow tiny and then disappear entirely, either swallowed by the distance or snapping into the strange super-space that existed beyond the speed of light. He turned from the window, chuckling. Stutsman snarled at him: "What's so funny?" The scientist glared at the wolfish face and without speaking, walked to the desk and sat down. He reached for pencil and paper. Chambers walked over to watch him. "You've found something, Doctor," he said quietly. Craven laughed, throatily. "Yes, I have. I've found a lot. Manning thinks he can keep us out here, but he's wrong. We'll be in the Solar System less than a week after he gets there." Chambers stifled a gasp, tried to speak calmly. "You mean this?" "Of course I mean it. I don't waste my time with foolish jokes." "You have the secret of material energy?" "Not that," the scientist growled, "but I have something else as valuable. I have the secret of Manning's drive: I know what it is that enables him to exceed the speed of light ... to go ten thousand times as fast as light ... the Lord knows how much faster if he wanted to." "No ordinary drive would do that," said Chambers. "It would take more than power to make a ship go that fast." "You bet your life it would, and Manning is the boy who's got it. He uses a space field. I think I can duplicate it." "And how long will it take you to do this work?" "About a week," Craven told him. "Perhaps a little longer, perhaps a little less. But once we go, we'll go as fast as Manning does. We'll be short on power, but I think I can do something about that, too." Chambers took a chair beside the desk. "But do we know the way home?" "We can find it," said Craven. "But there are no familiar constellations," objected Chambers. "He dragged us out so far that there isn't a single star that any one of us can identify." "I said I'd find the Solar System," Craven declared impatiently, "and I will. Manning started out for it, didn't he? I saw the way he went. The Sun is a type G star and all I'll do is look for a type G star." "But there may be more than one type G star," objected the financier.
