Storyline

The wife and mistress of a sadistic boarding school headmaster plot to kill him. They drown him in the bathtub and dump the body in the school's filthy swimming pool... but when the pool is drained, the body has disappeared - and subsequent reported sightings of the headmaster slowly drive his 'killers' (and the audience) up the wall with almost unbearable suspense...

The Devil You Say
10 March 2004 | by writers_reignSee all my reviews

The odds against writing and directing two all-time classic thrillers/suspensers back to back must be fairly remote, featuring your wife in both remoter still, and starring Yves Montand in the first (The Wages Of Fear, in case there are any first-time buyers out there) and his wife, Simone Signoret in the second, astronomical. Say hello - and tip your hat while you're about it - to Henri-George Clouzot who pulled off this double whammy with ease. Clouzot made only a handful of films but those he did make were worth seeing, from Le Corbeau thru L'Assassin habite du 21 thru Quai des Orfevres and up to Wages and this one. Again many previous commenters have set the scene and described the plot and most of them are more than positive in their praise. I can only endorse their opinions and raise a glass to all involved especially Paul Meurisse and Charles Vanel who tend to get lost in the shuffle. 9/10
