Charlie Chan at Monte Carlo is a 1937 American mystery film directed by Eugene Forde and starring Warner Oland, Keye Luke and Virginia Field.

The film features Keye Luke as Charlie's son Lee and character actor Harold Huber as a French police inspector.

Although Charlie and Lee are in Monaco for an art exhibit, they become caught up in a feud between rival financiers which involves the Chans in a web of blackmail and murder.

But Chan notices that in order to make certain the bonds were discovered, their briefcase had been opened with a special key that very few people had access to, and the bartender was not one of them.

Back at the Karnoff mansion, Chan exposes the killer, who had been embezzling in order to keep femme' fatale Evelyn Grey (Field) in the style to which she had become accustomed.
