Adapted by Dominique Roulet from his own novel it doesn't take long to realise that we are in Georges Simenon territory here. Sinister provincial undercurrents, skeletons in the closet and a collection of morally ambiguous, largely dysfunctional characters. It also enables director Claude Chabrol to take aim at his customary target of the beastly bourgoisie. Ingredient X comes in the shape of the truly extraordinary character that is Inspector Jean Lavardin.

He is a maverick who seems to appear from nowhere, is answerable to no one, assumes the role of judge and jury and has his own particular methods of extracting the truth! Jean Poiret is simply superb in the role.

The convoluted plot is almost as labyrinthine as that of 'The Big Sleep' but the performances carry us through. Great support here from M. Chabrol's former spouse Stéphane Audran as wheelchair-bound Madame Cuno and inveterate scene-stealer Michel Bouquet as a flakey lawyer. He had previously appeared in three of Chabrol's worst films and two of his best. Sultry Caroline Cellier, married at the time to Poiret, is the vamp. The nymphet is the enchanting Pauline Lafont who tragically met with a fatal accident at just 25.

Chabrol again utilises his favoured cinematographer Jean Rabier and the suitably menacing score is supplied by his son Matthieu.

Striking while the iron was hot, Chabrol and the excellent Poiret followed up the following year with 'Inspector Lavardin' after which the character was consigned to the small screen. Unsurprisingly Dominique Roulet went on to write a Maigret television series in the late 90's. It is indeed a cruel irony that the follow-up featured Bernardette Lafont, mother of the ill-fated Pauline.

Critics at the time welcomed this film as Chabrol's return to form and although nothing that he did thereafter could really compare with the ones he gave us during his Golden Period from 1968 to 1973, he still produced a few interesting, unsettling and slickly professional pieces, notably those starring super Huppert. Strangely, an actor whose persona seemed ideally suited to Chabrol's oeuvre, Gérard Depardieu, worked with him just once on 'Inspector Bellamy'. Not only Chabrol's swansong but a film which has more than a passing nod to Simenon.
