Henri-Georges Clouzot was often referred to as the French Hitchcock. In fact, Alfred Hitchcock felt his soubriquet Master of Suspense was so threatened by the director that he made Psycho in an attempt to outdo Les Diaboliques, Clouzot’s masterful murder mystery.
In this chilling morality tale, the browbeaten wife and abused mistress of a violent and sadistic headmaster conspire to murder him and dump his body in the school pool.
However, when the pool is drained the body has disappeared, and the ghostly form of the victim seems to be stalking the old school halls.
Calculating, callous and supremely cynical, it is obvious why Hitch was so scared.
