"No, he doesn't," snapped Professor Hemmingwell. "This is something I developed that only the commander and myself know about."
"So, if you and Commander Walters are the only ones that know about it," said Steve Strong slowly, "then a saboteur would have thought it unimportant and concentrated on the rest of the mechanism."
"Looks that way," mused Connel. "But there is still the possibility that it was an accident, as the professor said."
Strong looked at Connel questioningly and then back to the wreckage. The unit had been hurled from the upper deck of the spaceship, down to the main deck, and it looked as if someone had trampled on its delicate works.
"I'll have a crew put right to work on this," said Hemmingwell.
"Commander," Connel suddenly announced, "I'm going ahead with my trip to Mars to inspect the testing receivers. I don't think this incident is serious enough for me to delay leaving, and if Professor Hemmingwell and his men can get this unit back in operation in twelve hours, then there's very little time lost and we can go ahead with the tests on schedule."
