"No, he didn't," the Air Ministry official said. "That Swordfish plane was assigned to one Flight Lieutenant Barker who has been at this Base for the last six months. His mechanic told Squadron Leader Hays and myself that he was to take it up for testing this morning. The mechanic saw the plane take off and believed Barker was in the pit. Barker wasn't. Two hours ago they found Barker's body hidden in an old fuselage in the hangar. He had been stabbed through the heart. Murdered!"

Dave and Freddy stood there in stunned silence for a moment. Then the words fairly leaped off Dave's lips.

"And no replacement by the name of Steffins has joined this squadron today?" he asked.

"No one," Manners replied. "Nor has that Fairey Swordfish returned. It's long overdue right now, as regards fuel. So I think there's just one answer to that. After he shot you down he probably headed for the coast of occupied France. But enough of that for the moment. Sit down, you two, and tell me everything that happened. I know a little of it from a radio message the commander of the Tornado sent me. That's one of the reasons why I flew down here from London at once. And I can guess a little of the rest. However, I want to hear it all from you two. Go ahead, and don't leave out a single thing no matter how unimportant it may seem to you. Better start with the moment you left my office at Adastral House."

Some fifteen minutes later Dave and Freddy had given a detailed account of every minute of the time since they had left the Air Ministry in London. As ordered they didn't leave out a thing. They even related their own conversations, word for word as near as they could remember. Air Marshal Manners listened in silence right through to the end. He didn't interrupt once. He didn't even nod or make any kind of a gesture. He simply sat in the chair moving his steel blue eyes from one face to the other.

"And that's all of it, sir," Dave ended the narration for both of them. "There's probably a hundred other things we should have done. And maybe we made ... I mean, I made a mess of that meeting with Steffins on the train. Perhaps we should have made some kind of a report to you. But...."

"Take it easy, Dawson," Air Marshal Manners finally spoke up. "And you, too, Farmer. You two don't have to apologize for a single thing. Great guns, your attempt to crash that U-boat deserves the Victoria Cross in my opinion. No, you don't have to feel badly about a single thing. Fact is, I'm the one to blame for things going all wrong. At any rate I'm taking the blame. As for that Steffins meeting, it perhaps really didn't mean a thing. There's lots of lads who like to go around posing as officers. He may have been one of them. Then, too, he may have been Baron von Khole."

Both Dave and Freddy sat up straight in their chairs.

"Baron von Khole, sir?" Dave finally asked. "Is he a Nazi agent?"

Air Marshal Manners nodded and a look of smouldering anger came into his eyes.
