She Fell Among Thieves (1978)

While on a Pyrenees vacation in 1922, upright English gentleman Richard Chandos (Malcolm McDowell, A Clockwork Orange, Heroes) encounters the villainous Vanity Fair (Eileen Atkins, Cold Mountain). Mistress of the turreted Chateau Jezreel and leader of a motley band of criminals, she will inherit millions if she can force her stepdaughter to marry. Pitting his wits against this formidable adversary, Chandos determines to rescue the beautiful young woman. But Vanity Fair keeps one step ahead of him, a trick forever up her sleeve and murder in her heart.
