"There's one thing I didn't tell you because I didn't want to prejudice your thinking. The psychiatrists agree with you." "The psychiatrists?" The agent's brow furrowed in a question. "They've restudied the records exhaustively, ever since we first knew there was a saboteur in the crew. "They've weighed their egos, dissected their personalities, analyzed their capabilities, literally taken them apart and put them together again. I got their report just this morning." Gotch looked speculatively at the agent. "Your suspect is also their choice. Only there is no traitor." "No traitor?" The agent started visibly. "I don't get you." "No traitor," Gotch echoed. "This is a tougher nut than that. The personality profile of one man shows a distinct break." He looked expectantly at the agent. "A plant." The agent muttered, the words thoughtfully. "A ringer--a spy who has adopted the life role of another. That indicates careful planning, long preparation." He muttered the words aloud, talking to himself. "He would have had to cover every contingency--friends, relatives, acquaintances, skills, hobbies--then, at an exact time and place, our man was whisked away and he merely stepped in." He shook his head. "That's the kind of nut that's really tough to crack." "Crack it," Gotch said. The agent got to his feet "I'll dig him out," he promised savagely. * * * * * The drive to rehabilitate Red Dog became a frenzy in Crag's mind. He drove his crew mercilessly, beset by a terrible sense of urgency. Nor did he spare himself. They rigged lines in the dark of the moon and rotated the rocket on its long axis until the break in the hull was accessible. Crag viewed it with dismay. It was far longer than he had feared--a splintered jagged hole whose raw torn edges were bent into the belly of the ship. They finally solved the problem by using the hatch door of Drone Charlie as a seal, lining it with sheets of foam from Bandit, whose interior temperature immediately plummeted to a point where it was scarcely livable. Prochaska bore the brunt of this new discomfort. Confined as he was to the cabin and with little opportunity for physical activity, he nearly froze until he took to living in his space suit. Crag began planning the provisioning of Red Dog even before he knew it could be repaired. During each trip from Bandit he burdened the men with supplies. Between times he managed to remove the spare oxygen cylinders carried in Drone Charlie. There was still a scant supply in Drone Baker, but he decided to leave those until later.
