The Strange Vice of Mrs. Wardh

The Strange Vice of Mrs. Wardh (Italian: Lo strano vizio della Signora Wardh) is a 1971 giallo film directed by Sergio Martino, and starring George Hilton, Edwige Fenech, Cristina Airoldi, Manuel Gil, Carlo Alighiero, Ivan Rassimov and Alberto de Mendoza. Its plot follows the wife of a diplomat who finds herself being stalked by her former abusive lover in Vienna.

The letter "h" was added to the name "Ward" when an Italian woman named Mrs. Ward threatened legal action over the original title's potentially damaging her good name, just before the film was released. The film was originally released under the title Blade of the Ripper in the United States. It was also released under the alternate titles Next! and The Next Victim.
