Roger hesitated and then replied, "There's one way to find out."

"How?" asked Tom.

"Take a look in the communications logbook on the control deck."

"We can't, Roger." Tom shook his head. "Vidac's got his own men planted
in every one of our departments."

"Yeah," growled Astro. "I been watching the way that guy Smith takes
care of the power deck and, believe me, it makes me burn. Why, he hasn't
washed down the atomic motor casing once since we blasted off!"

"Wait a minute!" cried Roger suddenly. "Jeff Marshall!"

"Jeff?" asked Tom. "What about him?"

"He can get to the control deck and take a look at the logbook,"
answered Roger.

"Say, that's right," said Tom.

"Come on," said Roger. "Let's finish off this tour and get back to the
_Polaris_. If Vidac's on the level, he'll have sent your report to
Captain Strong. If not, we know where we stand."

Astro shook his head slowly. "Honestly, fellas, I don't know whether to
hope he did or didn't."
