Inspector Duff from Scotland Yard is tasked with solving a perplexing murder that takes place at a renowned London hotel, where a deaf elderly American man is killed during a family trip. As he investigates, the focus shifts to various potential suspects, including the tour group leader, a nervous traveler, and even a notorious gangster, but the lack of evidence complicates matters. Just as the case deepens with another murder on the group's journey to Hawaii, Duff seeks the expertise of his old friend, Charlie Chan, who ultimately takes charge of the investigation.
