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.
