I was not surprised at reading the name of James McBirney on the detective's card, underneath which was the title of the Automobile Underwriters' Association. But I was more than surprised when the younger of the visitors handed us a card with the simple name, Mortimer Warrington. For, Mortimer Warrington, I may say, was at that time one of the celebrities of the city, at least as far as the newspapers were concerned. He was one of the richest young men in the country, and good for a "story" almost every day. Warrington was not exactly a wild youth, in spite of the fact that his name appeared so frequently in the headlines. As a matter of fact, the worst that could be said of him with any degree of truth was that he was gifted with a large inheritance of good, red, restless blood, as well as considerable holdings of real estate in various active sections of the metropolis.
