He saw his boot on the hull surface, sliding slowly, creeping back and stretching his leg, suddenly it broke loose; he lurched to one side, and the other boot began sliding. There was a terrible ache in his arms, as though some malignant giant were tearing at him, trying to wrench him loose as he fought for his hold. There was one black instant when he knew he could not hold on another second. He could see the blue flame of the jet streaming behind him, the cold blackness of space beyond that. It had been a fool's idea, he thought in despair, a million-to-one shot that he had taken, and lost.... And then the pressure stopped. His boots clanged down on the hull, and he almost lost his hand-grip. He stretched an arm, shook himself, took a great painful breath, and then clung to the strut, almost sobbing, hardly daring to move. The ordeal was over. Somewhere, far ahead, an orbit-ship was waiting for the Ranger to return. He would have to be ready for the braking thrust and the side-maneuvering thrusts, but he would manage to hold on. Crouching against the fin, he would be invisible to viewers on the orbit-ship ... and who would be looking for a man clinging to the outside of a scout-ship? Tom sighed, and waited. Jupiter Equilateral would have its prisoners, all right. He wished now that he had not discarded the stunner, but those extra pounds might have made the difference between life and death during the blastoff. And at least he was not completely unarmed. He still had Dad's revolver at his side. He smiled to himself. The pirates would have their prisoners, indeed ... but they would have one factor to deal with that they had not counted on. * * * * * For Greg it was a bitter, lonely trip. After ten hours they saw the huge Jupiter Equilateral orbit-ship looming up in the viewscreen like a minor planet. Skilfully Doc maneuvered the ship into the launching rack. The guards unstrapped the prisoners, and handed them pressure suits. Moments later they were in a section in crews' quarters where they stripped off their suits. This orbit-ship was much larger than Roger Hunter's; the gravity was almost Mars-normal, and it was comforting just to stretch and relax their cramped muscles. As long as they didn't think of what was ahead. Finally Johnny grinned and slapped Greg's shoulder. "Cheer up," he said. "We'll be honored guests for a while, you can bet on that." "For a while," Greg said bitterly. Just then the hatchway opened. "Well, who do we have here?" a familiar voice said. "Returning a call, you might say. And maybe this time you'll be ready for a bit of bargaining." They turned to see the heavy face and angry eyes of Merrill Tawney. 8. The Scavengers of Space
