Your Vice Is a Locked Room and Only I Have the Key

Your Vice Is a Locked Room and Only I Have the Key (1972) is a Sergio Martino giallo you can watch online on iFILM. Oliviero, a washed-up writer drowning in cheap wine, has turned his crumbling family villa into a stage for drunken parties and public cruelty toward his wife Irina.

Then women start turning up butchered nearby, and Oliviero — who knew far too many of them — becomes the obvious suspect. His niece Floriana arrives uninvited, and she is pure cold calculation: she seduces her uncle, then Irina, quietly setting husband and wife against each other while guests keep dying. Edwige Fenech plays Floriana with the lazy menace that made her a genre icon.

Martino loosely twists Poe's "The Black Cat" into the plot — hence the title and the black cat named Poe prowling the halls. This one's for fans of grimy '70s Euro-gothic: baroque interiors, lurid color, and a morality that curdles by the reel. Squeamish viewers should stay away.
