Bedelia (1946)

"MARGARET LOCKWOOD as BEDELIA who had more than her share of men, jewels, and love and wanted more, more, MORE!"

Bedelia Carrington is living happily, it appears, in Monte Carlo with her husband Charlie Carrington. But a cultivated young artist, Ben Chaney, begins probing into her past with curious concern. Chaney, who is really a detective, learns that Bedelia's obsession for money has led her, in the past, to husband-poisoning for the insurance money.
