"Haven't tried it," Prochaska admitted. "I woke you up as soon as I found what had happened." He reached over and turned a knob. After a few seconds a hum came from the console. "Works," he said.

"See how quickly you can make repairs," Crag ordered. "We've got to hook onto the drone pretty quick."

He swung impatiently toward Nagel. "Was anyone up during your watch? Did anyone go to the commode?"

Nagel said defensively: "No, and I was awake all the time." Too defensive, Crag thought. But no one had stirred during his watch. Therefore, the sabotage had occurred between midnight and the time Nagel wakened Prochaska. But, wait ... Prochaska could have done the sabotage in the few moments he was at the console after Nagel woke him. It would have taken just one quick slash—the work of seconds. That left him in the same spot he'd been in with regard to the time bomb.

He grated harshly at Nagel: "Wake Larkwell and get on with the airlock. And don't chatter about what's happened," he added.

"I won't," Nagel promised nervously. He retreated as if glad to be rid of Crag's scrutiny.

"A lousy mess," Prochaska grunted.

Crag didn't answer.

"If we don't solve this, we're going to wind up dead," he pursued.

Crag turned and faced him. "It could be anybody. You ... me."
