"Sorry, sir?" Dave echoed, and gave him a questioning look.

The man reached up his good hand and touched the strip of plaster over his eye.

"Got a bit of a crack, and it put me off my napper for a spell," he said. "I was pretty much in a daze while you lads were saving our lives. When I came around, I found myself in my regular office in the War Office building. Must have walked all the way there. Everything came back to me clear as day, but you and those fire fighting chaps had left the spot by the time I got back there. But I certainly want to express my heartfelt thanks to you two, now. I certainly owe my life to you."

"We're glad we were of service," Freddy said, as embarrassed crimson seeped up into his cheeks. "How about the others, sir? Are they getting along all right?"

"Coming along fine," the other said. "Miss Trumble, my secretary, will be out of things for a bit, and I'll certainly miss her. Smartest woman in the service. But that's a jolly sight better than losing her completely. By Jove, this is like a cinema thriller, isn't it! My word!"

Dave and Freddy moved their feet uncomfortably and glanced at Air Vice-Marshal Saunders. The high ranking officer was grinning broadly and slowly nodding his head up and down.

"So you simply just went to take a look, eh?" he murmured. "Knew perfectly well that it was much more than that. You two certainly have the reputation for chasing after trouble, and whipping it."[1]

The air vice-marshal suddenly stopped short. The smile faded from his face, and he stared gravely at the two young R.A.F. pilots for a moment or two.

"And that is just why you are here," he said presently. "This officer, as you probably have guessed already, is Colonel Fraser, of British Intelligence. He is the one who wishes to speak with you. I only suggested to him that you two should have first chance to listen to what he has to say. Shall we all sit down? Colonel, are you ready to start?"

The Intelligence officer seemed to have difficulty in tearing his eyes from the two boys. He finally succeeded, and nodded. And as though a curtain had been drawn across his face, he too became grave and unsmiling.
