Thanks to the excellent template by the Swiss author Friedrich Dürrenmatt, this crime film is atmospherically dense and thrilling to the end. Heinz Rühmann was already an established star and this is one of his best movies. The unknown Gert Fröbe made his breakthrough and earned rightfully the role of James Bond villain Cedric Goldfinger. Anyone who sees, knows why. The supporting roles are also very well cast, and the film music is almost a classic. On top of that, the film is quite critical for the 1950s and deals with false accusations against marginalized groups and discrimination against children of divorced parents. The film feels modern and fresh to this day, it's a classic!
