A woman returns to Vienna after a year in New York with her new husband, and her life is turned upside down by a series of encounters with a new lover, an old lover with whom she had a sadomasochistic affair (her "strange vice" is violent sex), and a razor wielding killer. A twisting and suspenseful giallo with an excellent score and plenty of blood, plus the lovely Ed Fenech in all her naked glory. The ending is pretty preposterous and doesn't make much sense, but that's par for the course.

Decent giallo with all the requisite plot twists, black gloves, and naked Edwige Fenech. The bloodshed is a bit less visceral than usual, and there's more attention to the increasingly blurred lines between feverish memories and reality. Despite that, it's never difficult to follow.
