"The Black Camel" (1931) A Warner Oland - Charlie Chan Photoplay

Movie star Shelah Fayne is making a picture on location in Honolulu, Hawaii. She summons mystic adviser Tarneverro from Hollywood to help her decide whether to marry wealthy Alan Jaynes, a man she has known for only a week. Her friend Julie O'Neil worries, however, that the famous psychic has too much influence over Fayne. Meanwhile, Julie has fallen in love herself with local publicity director Jimmy Bradshaw.

Honolulu Police Inspector Chan pretends to be a humble merchant, but Tarneverro sees through his impersonation. Chan mentions to him the yet unsolved murder of film star Denny Mayo, committed years before.

Then Jimmy finds Shelah's body; she has been murdered. Julie makes him remove Shelah's ring before calling for the police.

Chan investigates. He invites Tarneverro to assist him. Tarneverro reveals that Shelah told him she was in love with Denny and was responsible for his death, but kept quiet to protect her career.

The suspects are many, but after various startling revelations, Chan eventually identifies the killer and the connection to Danny Mayo's death.
