By the time Simenon's 1956 novel En cas de malheur was filmed, in 1958, 30 of the author's books had been adapted for cinema (only about a third of them Maigrets). Starring Jean Gabin opposite Brigitte Bardot, the film - whose title was translated as Love is My Profession - caused a stir for its nude scenes (pictured below), and is a good deal racier than another version 40 years later with Gérard Lanvin and Virginie Ledoyen, En plain coeur (In All Innocence), directed by Pierre Jolivet - Luc Besson's collaborator on Le dernier combat (1983).
From then on, the 1958 film is surprisingly explicit: the first time he visits her, he comes too soon; once established in lodgings by Gobillot, Yvette institutes a ménage with her maid - a situation familiar from Simenon's own domestic life, where one maid is said to have asked another, 'On passe toutes à la casserole?' - both scenes are dropped in the 1998 version. (The maid in Claude Autant-Lara's original film is played by Nicole Berger, a beguiling presence who starred in an early Eric Rohmer short but died in a car crash aged only 32.) Yvette may be doing her best to keep Gobillot's interest alive, but there's surely also a hint of a lesbian aspect to her relationships with female accomplices and flatmates.
Jolivet's version is much less sophisticated than its predecessor: Gobillot's childlessness is highlighted in an awkward scene where his wife (Carole Bouquet) receives some adoption documents; and while Bouquet's role is more conventional, in the 1958 version, Edwige Feuillère portrays the same character as her husband's equal, who humours - even encourages - his affairs until they get out of hand. There's a lovely scene where Feuillère nevertheless hides her glasses quickly from her husband; one of that film's best images sees her flinging a giant bouquet of flowers meant for the mistress all over her husband's desk in the apartment that also serves as his office, a detail taken straight from the book. (The set up of their bedrooms, connected by a shared bathroom, is also pure Simenon.)
Where the 1998 film struggles most is in the portrayal of the lawyer: he is not supposed to be jealous when Yvette reignites an affair with someone of her own age - only Gabin can carry off Gobillot's knowing, stubborn insouciance. He's helped by some great lines and the 1958 film has some other nice touches, including the Middle Eastern music that blares in the miserable hotel where Yvette's young lover lives. The two films have completely opposing finales and yet, being Simenon, the outcome is the same - but only one ends with a haunting shot worthy of Casablanca's close.
