"Blessed wonder you didn't!" Squadron Leader Markham said, and hid a faint smile by wiping his mouth with his hand. "You figured the spot where the explosion occurred, I suppose?"

"Yes, sir," Freddy replied instantly. "From my own position I judged it to be about half way between Boulogne and Lille. I didn't go and investigate because I assumed that it was the bombers I had tagged blasting some Jerry ammo dump, or something. So I just came on back home, and landed. Sorry, sir, but.... Well, I thought it best I tell you, considering."

"Well, fessing up may help you a little," Markham grunted. "Doesn't excuse your being a crazy idiot, though."

Freddy started to apologize again, but checked it as Colonel Trevor leaned toward him.

"The location of that explosion, Farmer!" he said sharply. "You are sure of it? Positive?"

"Oh quite, sir," the English youth assured him. "Fact is, the blinking glare lighted up some landmarks that I recognized easily. But, as I say, it was probably those bombers of ours giving a Jerry ammo dump, or rail-head, a good drubbing."

"It wasn't!" Group Captain Ball cut in with a violent shake of his head. "The Bomber Command received very definite orders not to send a single unit over that area Tuesday night. It was to be left strictly alone so that the photo patrol planes would be able to work unhindered. No, none of our bombers were over that point Tuesday night."

"By the way, Farmer," Colonel Trevor got in quickly. "Did you happen to note the time of the explosion, by any chance?"

The English youth pursued his lips and squinted his eyes at the office wall in a mannerism of deep and concentrated thought. After a moment he sat up a bit straighter and nodded.

"Yes, of course, I did, sir!" he replied. "I distinctly remember glancing at the instrument board watch. I remember because I was flying with all dash lights out, and the glare of the explosion was bright enough for me to see the time. It was exactly twenty-seven minutes before midnight, sir!"
