Behind them a red ship was falling--falling free! And vaporous masses, ripped to ribbons, were falling, too, while other wraith-like forms closed upon them in cannibalistic feasting. Their terrific speed swept them on into space. When the pilot could check it, and turn, they found that the red ship was gone. "After it!" Harkness was shouting. "She went down out of control, but they didn't get her. They've only sprung the door-ports a crack, releasing the internal pressure." He told himself this was true; he would not admit for an instant the possible truth of the vision that flashed through his mind--a ripping of doors--a thrusting snout that writhed in where a girl stood fighting. "Get it!" he ordered; "get it! I'll stand by for rescue." * * * * * He sprang for the switch that controlled the great rescue magnets. Not often were they used, but every ship must have them: it was so ordered by the Board of Control. And every ship had an inset of iron in its non-magnetic hull. His hand was upon the switch in an agony of waiting. Outside were other beastly shapes, like no horror of earth, that came slantingly upon them, but even their speed was unequal to the chase of this new craft that left them far astern. Harkness saw the last ones vanish as Chet drove down through the repelling area. And he had eyes only for the first sight of the tiny ship that had fallen so helplessly. Ahead and below them the sun marked a brilliant red dot. It was falling with terrific speed, and yet, so swift was their own pace, it took form too quickly: they would overshoot the mark.... Harkness felt the ship shudder in slackening speed as the blast from the bow roared out. They were turning; aiming down. The red shape passed from view where Harkness stood. His hand was tight upon the heavy switch. Chet's voice came sharp and clear: "Rescue switch--ready?" He appeared as cool and steady as if he were commanding on an experimental test instead of making his first rescue in the air. And Harkness answered: "Ready." A pause. To the waiting man it was an eternity of suspense. Then, "Contact!" Chet shouted, and Harkness' tense muscles threw the current into crashing life. * * * * * He felt the smash and jar as the two ships came together. He knew that the great magnets in their lower hull had gripped the plates on the top of the other ship. He was certain that the light fans of the smaller craft must have been crushed; but they had the little red speedster in an unshakable grip; and they would land it gently. And then--then he would know! The dreadful visions in his mind would not down.... Chet's voice broke in upon him.
