In November of 1924, a mysterious Hollywood death occurred aboard media mogul William Randolph Hearst's yacht. Among the famous guests that weekend were: film star Charlie Chaplin; starlet Marion Davies (who was also Hearst's mistress at the time); silent-film producer Thomas H. Ince (known for creating the first Hollywood-studio facility and for creating an "assembly line" system for filmmaking); and feared gossip columnist, Louella Parsons.
