Trintignant, in trenchcoat and trilby, investigates a bondage slaying, grilling the heroine in the victim's bedroom which somehow contrives to be also a monastery cell, with trussed-up nuns languishing compliantly in the adjacent sanctum sanctorum. This is Robbe-Grillet amusing himself by scrambling together images and situations out of the overlapping conventions of the murder mystery and the S/M fantasy, taking care never to join the dots to form a coherent narrative and indeed ensuring that no such joining-up can possibly be achieved. This being Robbe-Grillet, none of the characters is permitted anything so crass as everyday sexual congress, though the numerous erotic tableaux should stir even the jaded or disinclined, thanks to the presence of Olga Georges-Picot, playing (but of course!) both victim and defence counsel. Amid all the sleight of hand, the most impressive feat is Trintignant's performance which manages to be simultaneously poker-faced and extravagantly comic.
