An imperfect film about the perfect crime. Mastermind detective Kruger is the title character, who plots the deed. Believing his wife unfaithful, he kills a woman who has been blackmailing the suspected lover, and pins the crime on him. After the trial and conviction of the lover, Kruger's
wife still wants nothing to do with him. Kruger commits suicide, and sends a sealed letter to his confederates, who believe they convicted the right man. To pacify the censors of the time, the film destroys a good ending by sticking on an epilog: it was really the fictional writings of a
criminologist for publication. This film was a remake of a 1928 part-talkie of the same name.
