The original French title of this movie - Poulet au vinaigre - means vinegar chicken, but poulet also means cop, so it's a play on words. The detective film that results, the first several appearances of Inspecteur Jean Lavardin (Jean Poiret),takes the notions of the genre and gives it the spin that director Claude Chabrol is so famous for.

Three men in a small town - a lawyer named Lavoisier (Michel Bouquet),Dr. Morasseau (Jean Topart) and Filiol the butcher (Jean-Claude Bouillaud) - have been conspiring to take the house of Louis Cuno (Lucas Belvaux) and his invalid mother. They continually harass the twosome and take away any joy from their life, so after one particularly bad encounter, Louis puts sugar in the gas tank of the butcher, which leads to a fatal accident and brings Lavardin to town.

That's just the start of the story, as Lavoisier's mistress Anna (Caroline Cellier) and Morasseau's wife Delphine (Josephine Chaplin),who make an odd couple, but both quickly vanish. And then a statue of a nue Delphone shows up in the doctor's garden and a charred body in another car wreck. It seems like this town has more than its share of secrets.

Stéphane Audran, who plays Madame Cuno, also appears in the TV spin-off Les dossiers secrets de l'inspecteur Lavardin: L'escargot noir as a different character. She was married to Chabrol from 1964 to 1980 and obviously continued working with his professionally after. Their son Thomas appeared in many of his father's movies and has become a director and screenwriter himself.

After another undue interruption in my ongoing Chabrol tribute – incidentally, I messed up the date and he will only turn 80 on the 24th of June rather than last May! – I plan to tackle it in earnest now, a task which will occupy me till the end of the month (to go along with a parallel Dennis Hopper tribute).

Anyway, this proved to be another stepping-stone in the French director's erratic but prolific filmography; by the end of the 1970s, his career had suffered a decline but it got back on track with this enjoyable award-winning thriller (incidentally, the hybrid retitling for U.S. consumption was an unusual touch),one that was successful enough to warrant a sequel – INSPECTOR LAVARDIN (1986; a viewing of which is to follow this one) – and a brief TV series made between 1988 and 1990 which seems to be unavailable for re-appraisal.

Still, for all the film's typical elements of detailed setting, nuanced characterization and ironic outlook, it does not quite scale the heights of Chabrol's finest work due to an essentially flimsy plot: indeed, even such later – and ostensibly lower-profile – efforts as the recently-viewed THE CRY OF THE OWL (1987) involve a denser and more gripping narrative! This is not to say that COP AU VIN lacks suspense or surprise: actually, the latter concerns most of all the iconoclastic Inspector himself – in spite of a dapper facade, he is blasé, forthright (even referring to a character's effeminacy as "AC/DC"!) and not above breaking into premises sans warrant or intimidating suspects to get at the truth – belatedly called in to investigate a murder, only to be met with a very similar one soon after and, later, the disappearance of a woman, all of whom are tied to a property development company whose methods are not the most ethical either.

Jean Poiret, ideally cast here and who would of course reprise the central role in the sequel(s),had garnered a reputation as a playwright and even secured an Oscar nomination for co-writing LA CAGE AUX FOLLES (1978); then in 1992, the same year he died of a heart attack (at 65),he stepped into the director's chair with LE ZEBRE (which won him a posthumous Cesar for Best First Film)! Incidentally, later on in the decade, he married one of his co-stars here i.e. Caroline Cellier (who, years before, had been the leading lady in arguably Chabrol's masterpiece THIS MAN MUST DIE [1969]); besides the latter, the film under review featured two of the director's frequent protagonists in supporting roles: ex-wife Stephane Audran (playing an invalid) and a very slim Michel Bouquet. Also on hand is amiably kooky Pauline Lafont (daughter of Bernadette, another "New Wave" regular and who would actually co-star in INSPECTOR LAVARDIN) – whose promising career was brought to a premature end when she perished in a fall, at just 25 years of age, in 1988!

I've seen a handful of Chabrol films and have so far been impressed with all of them. This film is my first experience of Chabrol's work in the eighties and while I'm not surprised at the fact that it gets lambasted by some; and it's not quite up to the great French director's previous high standards, personally I found this to be yet another great example of Chabrol's moody and brooding direction coupled with an interesting plot line and some good performances. The plot is not quite as deep as the ones seen in previous Chabrol films, but there's still plenty to chew on. The base of the story is Madame Curo and her son Louis. They live in a house that is wanted by two unscrupulous people in the village, but what they don't realise is that the son can read their mail, owing to the fact that he works at the post office - which gives them an advantage. The plot kicks off properly when Louis puts sugar into the tank of one of the men's cars, which soon results in a fatal car accident. After the disappearance of the other man's wife, a hard nosed police officer is brought in to investigate.

This film has one of the strangest titles I've ever heard of - 'Poulet au vinaigre', translating literally as "Chicken with the Vinegar". Quite what that means, I have no idea. The film has a fair few different plots going on, but the one that Chabrol seems most interested in is the one surrounding Louis, who finds himself in the middle of a "war" that is a bit too big for him and has to deal with his needy, sick mother at the same time. The murder investigation does provide the film with one of its main narratives; but since it doesn't kick off until we're halfway through, it's clear that it wasn't Chabrol's main concern. The acting is very good all round, with Lucas Belvaux making a convincing lead and getting good support from Chabrol's ex-wife and regular muse Stéphane Audran, Jean Poiret; who is excellent as the formidable police officer and my personal favourite, the exquisite Pauline Lafont as the love interest. Chabrol seems to have a thing for ending his films abruptly, and that is the case here as while everything is wrapped up by the end, it is done in a matter of about five minutes. Overall, it's not hard to imagine why this film isn't as well liked as some of Chabrol's other work - but for my money it's still a more than worthwhile thriller and comes recommended.
