As the man shouted the last his big hand flashed out with the speed of a striking cobra. Dave didn't even see it coming. He only felt the stunning blow on the side of his head. And the next thing he knew he was flat on his back on the ground, blinking goggle eyed up at the sky. The toe of a boot dug into his ribs.

"Get up, infant swine!" he heard the voice of Colonel Comstadt. "I hardly touched you. So you are the American, Dawson, I have heard about? Bah! You haven't the strength of a chicken. Get up!"

Dave got shakily up onto his feet. Red fire was sweeping through his brain, and white fury was boiling up in his chest. He had just enough sense left, though, to refrain from hurling himself at the big hulk of a Nazi. You can't chop down an oak tree with a straw, and Dave had enough sense to realize it. However, as he met the Nazi's leering gaze he made a silent promise to himself that if the chance ever came...!

"Now, let that teach you to behave, and answer my questions!" Colonel Comstadt growled. "So! What were you three pilots doing over here?"

Dave didn't attempt to answer. A hunch he had had for some time was growing stronger and stronger. Was the reason the Nazis didn't shoot, when they had the chance, because they wondered what Freddy, Barker, and he were doing over the area? They really didn't know, or even suspect?

If that were true then there was even greater hope that he and Freddy might get out of this jam. As long as they kept the Germans wondering and guessing the longer the Germans would keep them alive. There was one thing the war had proved about the Nazi breed. They never threw away a man's life until they had drained the last drop of usefulness from his body. And that went double for espionage agents they caught in their traps.

"We were on patrol," Dave answered the question aloud. "We were on our way to contact some of our bombers."

"That's perfectly true," Freddy spoke up, instantly catching onto Dave's line of thought. "What other reason, for heaven's sake? And why such a lot of you chaps? You certainly do believe in superior numbers, don't you? But, then, you must have learned many startling things about the Royal Air Force, eh?"

The Nazi acted as though he had not heard. He ignored the English youth, and kept his gaze fixed on Dave. When he spoke his voice was surprisingly soft. Yet there was a deadly undertone to it.

"You have perhaps heard of Colonel Comstadt?" he asked. "You have perhaps heard of him?"
