Your Vice is a Locked Room and Only I Have the Key ★★★★

Another Sergio Martino sleazefest done with a style and skill that only Argento could top. This one's a bit of a trick because the giallo element only goes about halfway before Martino breaks this movie wide open into something out of Edgar Allan Poe and even Hitchcock. It's totally unexpected and keeps you guessing at what the hell he's going to show you next. Edwige Fenech plays a stronger character than she usually does and that's half the fun of the movie. Definitely one of Martino's best, if not the best of his career.
