Web of Passion (also released as Leda, original French title: À double tour) is a 1959 French/Italian psychological thriller film directed by Claude Chabrol and based on the novel The Key to Nicholas Street by American writer Stanley Ellin.

[2] In a country mansion in Provence, Henri and Thérèse live in grand style with their two grown-up children, Richard and Élisabeth.

A small villa next door is taken by a beautiful young Italian artist called Leda, who turned up with an ebullient Hungarian friend Laszlo.

The son Richard, seeing his mother's pain and shame if she loses her husband, goes secretly to the villa and kills Leda.

"[6] Time Out commented: "Chabrol's third film, greeted at the time as a Hitchcock pastiche,... has gained considerably in stature," and added that "the climactic murder of the mistress... reveals the first glimpses of the Fritz Lang influence later to flower in Chabrol's work.
