Like Graham Greene's so-called entertainments, this film veers into melodrama, but it never seemed unreal to me and was certainly a pleasure to watch. The highlight for me was the machinations of the lowlife hired to bring the heroine down. I also got drawn into the setting of the rooming house and the warmth of the more innocent people that give strength to the heroine. Acting, as always in a Chabrol film, is superb.
