Warner Oland as Charlie Chan in "The Black Camel" (1931) - feat.Béla Lugosi & Robert Young

Shelah Fane, a motion picture star filming in Honolulu, consults the mystic Tarneverro to decide whether to marry wealthy globetrotter Alan Jaynes, whom she met on the boat to Hawaii. During a crystal ball session, Shelah confesses that three years earlier she fell in love with her co‑star Denny Mayo and that she was in his house the night he was murdered. Agitated, she tells her protégé Julie O'Neill that she cannot marry Alan. Anna, Shelah's maid, is upset when she brings orchids from stage actor Robert Fyfe and sees Shelah tearing a photograph of Denny Mayo. Julie and Jimmy Bradshaw, a tourist bureau employee who wants to marry Julie, find Shelah stabbed to death in her pavilion and remove her emerald ring. Inspector Charlie Chan gathers the guests, all of whom were in Hollywood at the time of Mayo's murder. Chan's assistant Kashimo finds the ripped photograph of Mayo, and a beach bum whose shoes match footprints outside the pavilion is brought in. Fyfe, Shelah's ex‑husband, confesses to killing her, but Chan deduces he could not have done it and warns the guests not to leave the island. An unseen assailant shoots Smith on the beach. Chan learns from an Australian couple that Tarneverro is actually Denny Mayo's brother, Arthur. Fyfe says that after Shelah discovered Mayo had a wife in England, she shot him during a quarrel, and he confesses to the murder to protect her memory. Chan deduces that Shelah's murderer must have sat in the chair nearest the scratch, and a knife is thrown at him. Julie accepts Jimmy's proposal and agrees to stay in Hawaii. Chan has the suspects sit where they sat the previous night. Anna reveals she is really Mrs. Denny Mayo and admits killing Shelah. Tarneverro confesses he came to Hollywood to find his brother's murderer and says that when Shelah confessed to him, he told Anna. He asks to share Anna's fate. As Chan goes to arrest Anna, Jessop, the butler who loves her, pulls a gun, but after a struggle Chan disarms him. Jessop admits he shot Smith because he knew too much and that he threw the knife at Chan.
