The Strange Vice of Mrs. Wardh

“Always unheard… unseen… until he reached out to touch and caress!”

Julie Wardh (Edwige Fenech), an American heiress living among the wealthy in Vienna, starts receiving blackmail letters while a killer works through the city. Her husband is often away, and she suspects her cruel former lover Jean (Ivan Rassimov), while George (George Hilton) offers her an easy way to forget him. Sergio Martino keeps her at the center of it, a woman who can trust none of the three men near her.
