I must disagree with the previous commenter: this is not a bad film at all. The plot is constructed in such a way that it does keep you guessing about one thing or another for almost the entire running time, which I think is usually considered the key to the success of a movie like this. Whether the conclusion is plausible or not I don't know; I didn't mind it. The scriptwriter was Lukas Heller, and it's easy to see why he went on to have such a successful career: this movie is taut, suspenseful, and as I said it keeps you guessing. As for the cast: Michael Gough is great as always; Hans Borsody is also excellent as the killer; no one else is a real stand-out but no one lets the film down too badly either, though a better actress than Erika Remberg would have bumped the film up a notch.
According to several sources this is based on a Edgar Wallace story called "The Best Laid Plans of a Man in Love," which was published in Cosmopolitan magazine in 1927.
