Diabolique

The body of the dead husband (Paul Meurisse) disappears from the swimming pool, shocking the wife (Véra Clouzot) and mistress (Simone Signoret). The wife goes into the bathroom, only to find the husband's body in the bathtub. The body rises from the tub and starts to walk toward her. The wife dies of a heart attack. It turns out the husband faked the death and was conspiring with the mistress to kill the wife out of fright.
Thanks, Jeremy G!
