"'This is a private matter between Mr. Estes and myself, as he knows full well. So far as you and Mr. Indiman are concerned, call it what you like--a duel, or, better yet, a sporting proposition.' "'The stakes?' put in Crawfurd, feebly, for, shaken as he was, he could still grasp at the definite idea included in the last-named alternative. Sport and a wager--now he understood. "'The stakes?' repeated Balencourt. 'Well, they are hardly of a nature that either Mr. Estes or myself can intrust them to the keeping of a third party. But rest assured that the loser will pay; it is a debt of honor.' "Up to this moment I had kept silence, but now I must make my one try. 'He is but a boy,' I said, leaning my elbows on the table and seeking to plumb the soul-depths in the cold, gray eyes of the man who sat opposite to me. But Balencourt only laughed amusedly. "'Then he should not assume a man's--' "'Will you come now, Cousin Esper?' interrupted Estes. He pushed his chair noisily back, and we all rose. "'You won't wait for coffee?' said our host.

"Now, while Estes is a second cousin of mine, 'Betty' Catherwood is my niece, and so I considered that I had a double right to stick in my oar. But I wasn't prepared for the depth of trouble that I encountered in the glance George Estes turned on me. 'So bad as that!' I finished, lamely. "'It won't take long in the telling,' began the boy, desperately.
