Madeleine (1976)

Madeleine Smith (Ann Todd), the beautiful eldest daughter of a wealthy Glasgow family, begins an illicit love affair with the charming Emile (Ivan Desny), a working-class Frenchman. When she begins to suspect that Emile loves her only for her money and social status, Madeleine agrees to marry the man her iron-fisted father (Leslie Banks) approves of, wealthy and respectable William Minnoch (Norman Wooland). When Emile dies suddenly, suspicion points to Madeleine as his murderer.
