I Tre volti della paura

I Tre volti della paura literally "Three Faces of Fear," an Italian trilogy by Mario Bava featuring Boris Karlooff, was released in the U.S. as Black Sabbath.

The tales include "The Telephone," a taut little murder mystery with a lesbian subplot and supernatural twist, "The Wurdalak," an effective story featuring Karloff as a curly-haired vampire who feeds on members of his own family, and "A Drop of Water," an atmospheric ghost story about a nurse who steals the ring of a recently deceased medium whose corpse she prepared for burial.

It is the last tale that most disturbed me. Having returned home, the woman begins to hear a drop of water without an apparent source for the sound, a sound that she had heard in the home of the deceased medium when she knocked over a glass of water. Then a fly that seemed to come from everywhere and nowhere haunted her. Finally, well...the pictures tell the story.
