He threw down the towel with his old mischievous chuckle. "If you're going to start that game, Jack," he said, "you'd better spend your honeymoon at Vesuvius. It'll save you ruining yourself in matches."

We went downstairs to the sitting-room I had engaged, where tea was already laid. A minute later Mercia joined us. Despite all she had been through, she looked radiantly lovely as she came half shyly into the room. Indeed, Billy was so overcome that he jumped from his chair with a little gasp of open admiration.

"By Jove, Mercia!" he said. "You ought to be abducted twice a day. It makes you better-looking than ever."

She laughed sweetly, and came across to where I was standing. "I am afraid I shall never be more beautiful, then," she said, "unless there are some very reckless men in the world."

I drew her arm tenderly through mine. "I don't want you to be any more beautiful, Mercia," I said; "it would frighten me if you were."

There was a knock at the door, and a waiter entering announced "Mistaire Gordon."

Sleek and debonair as ever, my gallant defender followed hard upon his heels.

"Don't trouble to explain anything," he said, shaking hands all round. "I've got only ten minutes, and I've already heard full details about the piracy, of which, by the way, I thoroughly approve. I met Wilton in the hall."

"I wondered what had happened to him," I remarked. "We were expecting him up here to tea."

Gordon shook his head. "You won't get him," he said. "Wilton has some intelligence as a private detective, but outside his business he's a miracle of shyness and stupidity." Then he smiled in his quiet fatigued way. "He asked me to congratulate you, however."
