This is a detective novel. In the pages which follow I have narrated a story of actual occurrence. No touch of fiction obscures the truthful recital. The crime which is here detailed was actually committed, and under the circumstances which I have related. The four young men, whose real names are clothed with the charitable mantle of fiction, deliberately perpetrated the deed for which they suffered and to-day are inmates of a prison. No tint or coloring of the imagination has given a deeper touch to the action of the story, and the process of detection is detailed with all the frankness and truthfulness of an active participant.
