A thief and killer stalks the streets of Paris, leaving a calling card from "Monsieur Durand" at the scene of each crime. But after a cache of these macabre identifications is discovered by a tradesman in the boarding house at 21 avenue Junot, Inspector Wens (Pierre Fresnay) takes lodging at the infamous address in an undercover bid to solve the crime, with unexpected help from his struggling-actress girlfriend Mila Malou (Suzy Delair).
Rare French 1940s black comedy
- The Murderer Lives at 21 review by GS
This film is so rare that it's not even mentioned in my 2017 Radio Times Film Guide. The director [Henri-Georges Clouzot] is, however, famous, having directed the thriller to end all thrillers - "The Wages of Fear" - in the 1950s.
Although it's a crime film with several murders, it's a blackly humorous film [well, 1940s French humour] and well worth watching if you're OK with b&w subtitled French films. There's a twist at the end of the film.
