The Film Mystery is one of eighteen detective novels by Arthur B. Reeve starring his best known character Professor Craig Kennedy and his trusty sidekick Walter Jameson, a newspaper reporter. The pair bears an unmistakable resemblance to the more famous British master sleuth and his doctor friend. The setting of this mystery is the early days of movie making, and the murder victim is Stella Lamar, “the beautiful idol of the screen, beloved of millions”, who collapses and dies during the filming of a scene for her latest movie.
