“Back to Terra,” commented McNaught, happily. “And an overhaul will mean at least one month’s leave.” He eyed Burman. “Tell all officers on duty to go to town at once and order the crew aboard. The men will come running when they know why.”

“Yes, sir,” said Burman, grinning.

Everyone was still grinning two weeks later when the Siriport had receded far behind and Sol had grown to a vague speck in the sparkling mist of the bow starfield. Eleven weeks still to go, but it was worth it. Back to Terra. Hurrah!

In the captain’s cabin, the grins abruptly vanished one evening when Burman suddenly developed the willies. He marched in, chewed his bottom lip while waiting for McNaught to finish writing in the log.

Finally, McNaught pushed the book away, glanced up, frowned. “What’s the matter with you? Got a bellyache or something?”

“No, sir. I’ve been thinking.”

“Does it hurt that much?”

“I’ve been thinking,” persisted Burman in funereal tones. “We’re going back for overhaul. You know what that means? We’ll walk off the ship and a horde of experts will walk onto it.” He stared tragically at the other. “Experts, I said.”

“Naturally they’ll be experts,” McNaught agreed. “Equipment cannot be tested and brought up to scratch by a bunch of dopes.”

“It will require more than a mere expert to bring the offog up to scratch,” Burman pointed out. “It’ll need a genius.

McNaught rocked back, swapped expressions like changing masks. “Jumping Judas! I’d forgotten all about that thing. When we get to Terra we won’t blind those boys with science.”
