Der Mörder wohnt in Nr. 21

Director Henri-Georges Clouzot's first film is an Agatha Christie style mystery, with the murderer constrained to the set of people in a boarding-house and a detective (Pierre Fresnay) investigating them. It's a playful script, buoyed by the perky Suzy Delair who is both his mistress and an aspiring opera singer (and in an interesting side note, Delair, a year younger than Olivia de Havilland, is as of this writing also still alive). The subject matter of a serial killer who leaves a calling card on his victims is of course serious, but it's presented here in a pretty light way, a bit like a stage play. It's also a little hokey in how its investigation proceeds and it's not all that kind to the French police who seem a bit foolish, but the resolution to the mystery is excellent and hard to see coming.

The film was made when the Nazis were occupying France, so Clouzot was working for the German production company Continental Films, and undoubtedly walking a tightrope (one that would get him into trouble with his countrymen in his next film, Le Corbeau). Some critics read veiled commentary about the Nazis in aspects of the plot (e.g. a murder shot from the perspective of the killer early on, or how heavy-handed police interrogations that border on torture can elicit a false confession), but I didn't see it quite as symbolically. The possible reference to a Nazi salute is intriguing though, and regardless, it's mind-boggling to think of this light mystery being made at this point in French history.
