Charlie Chan in London is a 1934 American mystery film directed by Eugene Forde. The film stars Warner Oland as Charlie Chan. This is the sixth film produced by Fox with Warner Oland as the detective, and the second not to be lost, after The Black Camel (1931).
Robert Altman's film Gosford Park, set in 1932, features a (fictional) character who produces the Chan films for Fox and claims to be in England doing research for Charlie Chan in London.
Plot
A young English man is convicted of the murder of one Captain Hamilton of the Royal Air Force and sentenced to hang. His sister and her fiancé, convinced of his innocence, ask visiting detective Charlie Chan to investigate and find the real murderer. In order to solve the mystery, Chan must visit a lavish English country manor house, where the suspects vary from the housekeeper to a lawyer. Events soon indicate that the murderer is still actively trying to avoid capture, but Charlie Chan must set a trap to reveal the criminal's identity. He turns out to be Paul Frank, a spy masquerading under the name Geoffrey Richmond, who had murdered Captain Hamilton to steal plans of a military invention Hamilton had made.[1]
