In the captain's cabin, Nuoy heard the voice. He snapped open the communication line between this cabin and the control room.

"What nonsense is this?" he shouted into the mike. "There is no way a dangerous condition can develop in the drive of these ships!" He was speaking the truth. Deep-space ships, all space ships, were hazard proof so far as the drive was concerned. He expected an evasive denial.

"Of course no dangerous condition can develop," the voice from the control room answered.

"Then what do you mean by making so stupid an announcement as this? What are you trying to do, delay my departure? I'll have you stripped of your rank for this piece of nonsense!"

Wrath was in his voice. Before this wrath captains, generals, even the president of Earth Government, trembled.

The voice coming from the control room did not tremble. "Aw, go buy a muzzle for your ugly face," it said, crisply. "Who in the hell do you think you're giving orders to, Dog-face?"

Nuoy was utterly speechless. White with fury, he headed for the control room. He'd teach Captain Martin proper respect for his betters. Charging through the door of the control room, he found there a doddering old man whom he vaguely recognized as having seen around Pluto Station. The old man was sitting in the control chair, a monkey wrench in his hand.

"Who the devil was that who was just speaking to me?" Nuoy demanded.

"Why, I don't know, Mr. Nuoy. No one was speaking from here."

Nuoy glared at him. His suspicions were aroused. "I believe you are lying to me. I believe you were the one who was talking to me like that. I'll have you know—" Nuoy advanced. While he explained what he was going to do, he thrust his head down until it was within a foot of the old man's face.
