"Damn it, Jack!" he said, as the boat ran up the bank and he leaped on shore. "I thought they'd downed you in that time. Look at the blighters!"

He pointed down the creek, where our late assailants were travelling away from us with a vigour which would have done credit to a championship pair at Henley. Then, sitting down on the bank, he burst into a roar of laughter.

"Oh, great!" he gasped, when he had sufficiently recovered. "Jack, my son, you're all right when it comes to gunning. You had me on as clean as a whistle. I'd have sworn they'd got you."

"If you hadn't come cruising around in that fashion, Billy," I said, "I should have got them. You've saved me from the horrid sin of shedding blood."

"I could have pipped them all right myself," he protested. "That Dago with the gun couldn't shoot for sour apples. How did it all come about?"

As briefly as possible I put him in possession of the facts. "It was a plant," I finished: "there's no doubt about it now. I should have been found shot, if I'd ever been found at all. Mr. Guarez and his pal would have cleared out, and Maurice, with a beautiful fat alibi to keep him out of trouble, would have stepped into the family property. It's a wicked world, William."

"You're right," said Billy, shaking his head; "but fortunately it makes a bloomer sometimes. I saw the whole thing. I'd tied my boat to the sea wall round the point there, and crawled up on to the top. I watched you punt over to the island and I was just coming along to keep you company when that misbegotten skunk let drive. I thought you were a goner, Jack! You did that stunt so devilish well it took me in completely."

"I hope you felt sorry," I said,

"Sorry!" laughed Billy. "I was in a black rage, I can tell you. If you hadn't popped up like a Jack-in-the-box, I'd have filled those two Dagoes fuller of lead than a racing yacht."

"I'm glad you didn't, Billy," I answered. "I'm looking forward to doing something in that line myself." Then I looked at my watch. "It's half-past six," I added. "That's the time the duck were due to arrive. I'm afraid we've frightened them!"
