Crag assigned Prochaska the task of monitoring the radio despite his plea to share in the more arduous work. The knowledge that one of his crew was a saboteur lay constantly in his mind. He had risked leaving Prochaska alone before, he could risk it again, but he wasn't willing to risk leaving any of the others alone in Bandit. Yet, Prochaska hadn't found the bomb! Larkwell had worked superhumanly at the task of rebuilding the Aztec--Nagel had saved his life when he could just as easily have let him die. Neither seemed the work of a saboteur. Yet the cold fact remained--there was a saboteur! Richter, too, preyed on his mind. The self-styled Eastern scientist was noncommittal, speaking only when spoken to. Yet he performed his assigned duties without hesitation. He had, in fact, made himself so useful that he almost seemed one of the crew. That, Crag told himself, was the danger. The tendency was to stop watching Richter, to trust him farther and farther. Was he planning, biding his time, preparing to strike? How? When? He wished he knew. * * * * * They toppled Red Dog in the dark of the moon. Larkwell had run two cables to manually operated winches set about twenty-five yards from the rocket. A second line extended from each winch to the ravine. The ends of these were weighted with rocks. They served to anchor the winches during the lowering of the rocket. Finally a guide line ran from the nose of the rocket to a third winch. Richter and Nagel manned the lowering winches while Larkwell worked with the guide line, with only small hand torches to aid them. It was approximately the same setup used on the Aztec--they were getting good at it. Crag helped until the moment came to lower the rocket, then there was little for him to do. He contented himself with watching the operation, playing his torch over the scene as he felt it was needed. It was an eery feeling. The rocket was a black monster bathed in the puny yellow rays of their hand torches. The pale light gave the illusion of movement until the rocket, the rocks, and the very floor of the crater seemed to writhe and squirm, playing tricks on the eyes. It was, he knew, a dangerous moment, one ripe for a saboteur to strike--or ripe for Richter. It was dark. Not an ebony dark but one, rather, with the odd color of milky velvet. The earth was almost full, a gigantic globe whose reflected light washed out the brilliance of the stars and gave a milky sheen to Crater Arzachel. It was a light in which the eye detected form as if it were looking through a murky sea. It detected form but missed detail. Only the gross structures of the plain were visible: the blackness of the rocket reaching upward into the night; fantastic twisted rocks which blotted out segments of the stars; the black blobs of men moving in heavy space suits, dark shadows against the still darker night. The eery almost futile beams of the hand torches seemed worse than useless.
