Italian thriller, a business associate tells a newly married woman her husband is a murderer, then blackmails her into sleeping with him. Luciano Ercoli (1970)

Before the influence of Dario Argento's The Bird with the Crystal Plumage permeated every corner of the giallo genre, another strain of these distinctive Italian thrillers enjoyed considerable success. These "melodrama gialli", heavily inspired by Clouzot's Les diaboliques, relied less on graphic violence and high body counts and more on psychological tension.
