"Impossible." "Okay, well try and make it from here." The Colonel added a few comments. They were colorful but definitely not complimentary. He got the distinct impression the Colonel wasn't pleased with events on the moon. When his cold voice faded from the communicator, Crag tried the analog. The grid scope came to life but it was blank. Of course, he thought, Drone Baker was cut off from earth by the body of the moon. It could not be simulated on the analog until it came from behind the blind side where the earth saucers could track its flight. "Morning," Larkwell said, sticking his head around the curtain. "How about climbing into your suits so we can get out of this can?" Crag studied his face. It seemed void of any guile. Nagel stood nervously behind him. "Okay," Crag said shortly. He hated to have Prochaska lose the precious moments. They hurriedly donned their suits and Nagel decompressed the cabin, Larkwell opened the hatch and they left. Crag closed it after them and released fresh oxygen into the cabin. Richter took off his suit and returned to his corner. His eyes were bright with interest. He knows, Crag thought. At 0630 the communicator came to life. A voice at the other end gave Drone Baker's position and velocity as if nothing had happened. The drone, on the far side of the moon, was decelerating, dropping as servo mechanisms operating on timers activated its blasters. It was guided solely by the radio controlled servos, following a flight path previously determined by banks of computers. Everything was in apple-pie order, except for the snafu in Arzachel, Crag thought bitterly. Prochaska worked silently, swiftly. Crag watched with a helpless feeling. There wasn't room for both of them to work at one time. The Chief's head and arms literally filled the opening of the sabotaged console. Once he snapped for more light and Crag beamed a torch over his shoulder, fretting from the inaction. Sounds came through the rear bulkhead where Larkwell and Nagel were working in the tail section. Strange, Crag thought, to all appearances each crew member was a dedicated man. But one was a traitor. Which one? That's what he had to find out. Richter would have been the logical suspect were it not for the episode of the time bomb. No, it hadn't been the German. It was either the competent Prochaska, the sullen Nagel or the somehow cheerful but inscrutable Larkwell. But there should be a clue. If only he knew what to look for. Well, he'd find it. When he did ... He clenched his fists savagely. At 0715 Alpine simulated the drone on the analog. Fifteen minutes later Prochaska pulled his head from the console and asked Crag to try the scope. It worked.
