"Yes, sir," he said doggedly. "I know I'm speaking out of turn, but you asked me, sir. So I gave you a truthful answer."

"The truth is always welcomed, of course," Group Captain Ball said a bit stiffly. "Supposing, though, instead of wasting time defending yourself, you explain why there would be no sense in carrying out such a stupid mission?"

"Just a minute!" Dave said as his cheeks got hot. "I didn't say the mission was stupid, sir. I didn't say, either, that carrying it out would be a waste of time. I meant that carrying it out as planned would be a waste of time, in my opinion."

"Why?"

It was Colonel Trevor who shot out the single word. He had leaned farther forward in his chair, and was regarding Dave not out of hostile eyes, but out of eyes that showed frank curiosity, and an earnest desire to learn the truth.

"Because of what's already happened, Colonel," Dave replied. "Look at it this way. Countless photo patrols were made over the terrain of Zone K Dash Twenty-Four. Each time Jerry planes were encountered and there was a scramble or two. At first the pictures didn't show anything of interest. Then suddenly they showed a lot of crazy changes in a certain area. Finally, the pictures gave every indication that that certain area had been completely evacuated. And lastly, a photo flight that went over at night failed to return. You follow me, sir?"

"Yes," the Intelligence officer grunted. "But you're only giving a case history of what's happened. We know all about that."

"Why did it happen?" Dave shot right back at him. "If you want my opinion I think it's because the Nazis knew all the time what we were up to. They saw our bombers upstairs, but no eggs were dropped. They saw our bombers circling around over the area day after day, and still no bombs came down. The Jerry fighter pilots tangled with our fighters, and the photo ships still stuck to their job. What in the world do you think the Nazis on the ground were imagining? That we were practicing formation flying or something? The heck they did! They knew darn well that we were taking pictures, and more pictures. And not being exactly dumb, they did the logical thing!"

The ghost of a smile quivered at the corners of Colonel Trevor's mouth. Even Markham and Group Captain Ball were having trouble keeping a straight face. The straight from the shoulder honesty of the young Yank was not exactly an every day occurrence in British Army life, and they were a bit more amused than they were shocked.

"And what was the logical thing for the Nazis to do?" the Intelligence officer eventually asked quietly.
