Surprisingly good, in fact rather splendid late Chabrol. We start with a young couple full of love and optimism as they bounce about running their hotel, bringing up baby and making eyes at each other. The wife seems to naturally do this semi flirting semi friendly stuff with everyone and gradually her husband begins to become jealous. We are never 100% certain but what at first seems six of one and half a dozen of the other descends into the 'hell' of the title as the green eyed monster truly comes to fruition. Initially delightful, this movie gets as dark as it possibly could and we are gripped, even perhaps more than with a Hitchcock as the terrible finale awaits.
