Then Clyde comes across Jim Morrison who says he's a journalist. His behaviour doesn't jell, and Clyde wonders if he can be trusted. Something more dreadful happens... Meg meets two young women who are in deep trouble, and the Pilleys try to help them. They think they have encountered the worst of their problems when psychic Meg senses their cabin has been broken into - not once, but twice. Why are they being watched? Are Meg and Clyde's lives in danger? Can they depend on ship security. More importantly - who is Jim Morrison?
