This later German Edgar Wallace Krimi packs plenty of both action and humor into its running time, as Scotland Yard investigates murder tied to a nightclub, as well as drug dealing and human trafficking. Inspector Perkins (Horst Tappert) is the lead investigator; his boss, Sir Arthur (Hubert von Meyerinck) takes a hand from time to time but also serves as part of the comic relief, particularly in his interactions with his secretary / assistant, Miss Mabel Finley (Ilse Pagé). The plot is a bit chaotic, but the whole is fairly fun viewing.
Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
Movie 273 for 2021.
