Time Out review:
When Catherine (Jacqueline Bisset) takes on Sophie (Sandrine Bonnaire) as housekeeper, her family's impressed by Sophie's aura of quiet responsibility, even though they're not convinced she knows how to serve dinner correctly. Snobbish but liberal, they nevertheless treat her generously. Only when she starts to consort with postmistress Jeanne (Isabelle Huppert), a gossip whom husband Georges (Jean-Pierre Cassel) suspects of opening the family mail, do they find real cause for complaint. But by then the women have a secret bond which excludes them from the safe cosseted world of Sophie's employers. Claude Chabrol's adaptation of Ruth Rendell's A Judgement in Stone benefits from the director's immaculate sense of social and psychological detail. The film's strong points are not mystery, suspense or even surprise, but Chabrol's flair for characterisation, careful pacing and solid evocation of bourgeois complacency and anti-bourgeois hatred creates a palpable sense of unease that fully justifies the shockingly violent finale. Ledoyen, the daughter of the household, is a discovery; Bisset returns to form; and Huppert, unusually vivacious, is terrific.
