Loose adaptation of an early novel by Georges Simenon, which would be remade with some success as Monsieur Hire in 1989. The attraction for Julien Duvivier in 1946 was the portrayal of mob mentality which reflects the improvised law of France in the months after WWII.
So Monsieur Hire (Michel Simon) is fitted up by his neighbours as the killer of a lonely spinster, purely because he is unpopular and different. This subplot unfortunately squeezes out the stronger theme of his voyeuristic obsession with a woman just released from prison (Viviane Romance).
And she unconditionally loves the real murderer (Paul Bernard). Anyone used to Hollywood crime films will be struck by how sleazy this is. The Production Code wouldn’t permit the assassin’s impassive revelation of utterly sordid sociopathy. Or the futility of the law… Or the post coital intimacy of the degenerate lovers.
Michel Simon is ideal casting as the resolute, deviant misfit. And there’s the eccentric community of sex workers, bumptious minor officials and ineffectual petit bourgeoisie standard in French crime pictures. This feels like the poetic realism of the ’30s. War is over but an ambient pessimism still hangs over the city, like fog.
