"What news of Jim?" he cried, the instant he saw me.

"Very sketchy," I answered. "He's the worst letter-writer in the world. You know he trod on a bit of orange-peel and broke his leg when he got back to England."

"He would." Petersen smiled. "That's just the sort of thing Jim would do. Men like him usually die of mumps, or the effects of a bad oyster."

"Quite so," I murmured, catching him gently by the arm. "And now come to the pub over the way and tell me all about it. The beer there is of a less vile brand than usual."

"But I can't tell you anything, my dear chap, that you don't know already!" he expostulated. "I am quite prepared to gargle with you, but——"

"Deux bières, ma'm'selle, s'il vous plaît." I piloted Petersen firmly to a little table. "Tell me all, my son!" I cried. "For the purposes of this meeting I know nix, and you as part hero in the affair have got to get it off your chest."

He laughed, and lit a cigarette. "Not much of the heroic in my part of the stunt, I assure you. As you know, the show started from Dunkirk, where in due course Jim arrived, armed with credentials extracted only after great persuasion from sceptical officers of high rank. How he ever got there at all has always been a wonder to me: his Colonel was the least of his difficulties in that line. But Jim takes a bit of stopping.

"My part of the show was to transport that scatter-brained idiot over the trenches and drop him behind the German lines. His idea was novel, I must admit, though at the time I thought he was mad, and for that matter I still think he's mad. Only a madman could have thought of it, only Jim Brent could have done it and not been killed.

"From a height of three thousand feet, in the middle of the night, he proposed to bid me and the plane a tender farewell and descend to terra firma by means of a parachute."

"Great Scot," I murmured. "Some idea."
