Charlie steps in to solve the murder of a wealthy American found dead in a London hotel. Settings include London, Nice, San Remo, Honolulu and Hong Kong. Fast-paced with lots of wisecracking.
Warner Oland's first appearance as Charlie Chan.
When they take the key out of the dead man's hand (it looks more like a woman's hand in the closeup), the hand has to be forced open but continues to open after the officer stops forcing it as the key and chain are removed. Subsequently, it assumes at least 4 different positions, 2 palm up, 2 palm down between shots. Lots of moving for a dead hand.
