"Our man!" he heard his own voice choke out. "The Nazi rat. On this flat-top all the time? Right under our noses, and we haven't spotted him until now? Good grief, how did that happen? How...?"

He cut off the rest because by then he was sprinting after Freddy Farmer, and he needed all of his wind for that. Freddy was halfway across the hangar deck, and the Nazi spy was walking casually toward the companionway on the other side. Suddenly, though, perhaps because he heard Freddy's running footsteps, or perhaps because Freddy called out, he turned his head. For the bat of an eyelash he pulled up short and stared, and then he broke into a mad run.

"That man!" Freddy Farmer's voice seemed to fill the entire hangar deck. "Stop him! Stop that man!"

Young Farmer's cry was directed at an aviation machinist's mate just coming out of the companionway on the other side. The Naval rating stopped, blinked, and stared at the man running toward him.

"A Nazi spy!" Farmer shouted. "Stop him!"

But Freddy's cries were just a waste of breath. The aviation machinist's mate started to put out a hand to signal the Nazi spy that somebody wanted him, but that's as far as he got. The running spy slugged him a terrific blow on the jaw and the Naval rating went down as though the deck had dropped out from beneath him. And in the next instant the spy had dived into the companionway and disappeared. Freddy Farmer was a good fifteen yards from the companionway opening, and Dawson was another twenty yards or so behind his pal.

In an effort to cut down the distance Dawson ducked under the wing of a plane, but he didn't duck low enough. The tip of the wing caught his shoulder, threw him off balance, and sent him sprawling onto the deck. He wasn't even dazed, though, and he was up on his feet almost instantly, but by then Freddy Farmer had disappeared into the companionway, too.

Choking and gasping for breath, Dawson plunged forward and went over the prostrate aviation machinist's mate in a leap and tore into the companionway. The sudden change of light blinded him for a split second, but he knew that the companionway turned sharp right at the end of twenty yards, and that at the end of the right turn there was the companionway ladder that led directly topside to the flight deck.

By the time he reached the turn he was used to the fairly dim light. But even at that he didn't see the figure sprawled on the deck until too late. The figure of Freddy Farmer. Dawson heard his own voice cry out his pal's name as he strived desperately to swerve off to the side. But his efforts were not enough. His left foot struck one of Freddy's legs and he went flying over young Farmer, and down in a heap.

All the colored lights in the world flashed in his brain. There was so much fire in his lungs that he couldn't breathe. He could only lay motionless, his face pressed against the companionway deck as the vibrations of the carrier's engines went through his whole body. The vibrations of the ship's motions plus the dry sobs of rage and fury that shook him.
