"How the hell can a piece of machinery look queer?" "Well, he did," said Sofi indignantly. "He looked as if he was going to take me apart, too!" Henry groaned. "Go on," he said resignedly. "Why, then R-7 wanted to know if I was put together or if I came all in one piece." She bit her lip. "He started to find out." She slipped off the oxygen suit.

He snapped the notebook shut, jammed it in his pocket. "Where are you going," Sofi asked as he started for the door. "Get my oxygen suit. I want a look at their mining worm." "You'd better take a crowbar along to fend
