Murder Ahoy

Mystery novelist Agatha Christie's intrepid spinster sleuth, Miss Marple, dares the high seas when she hears the call of Murder Ahoy. Miss Marple (Academy Award winner Margaret Rutherford) investigates when a fellow board member of an organization that mentors troubled juveniles is found dead. The authorities rule death by natural causes, but the spinster sleuth suspects otherwise. Now, at sea aboard the ship the organization uses to train the teens, Miss Marple discovers a finishing school for young thieves--and entirely too many suspects. But will she identify the murderer before he murders her?
