The following story was told to the writer by Nick Carter as being the most remarkable, and in many respects, the most mysterious case in his experience. It baffled the shrewdest detectives on the regular force, and had practically been abandoned when Nick Carter took hold of it. I tell the story in my own way and in the third person, but the facts, scenes and incidents are reproduced as nearly as possible in the great detective's own words.THE AUTHOR.
