Ian has returned. But from where? Everyone thinks he is mentally disturbed because he is claiming to be the grown-up Ian Forman, who everyone knows drowned when he was just a 12-year-old child. Even his wife Mary of over 40 years says she doesn't know him and although she's married to someone else, he still craves to be with her and she is enjoying the attention. His 'situation' is eventually explained when he establishes that he hasn't returned from the dead. No, he has returned from a parallel universe. Ian learns that he has enemies who wish him serious harm, not least Mary's violent extremely disturbed son Jonjo but also a sinister group of religious fanatics who are convinced he is a resurrected monster, now possessed by a demon. Fortunately, he also has some influential friends. Can Ian evade his determined enemies and persuade Mary to put her trust in him?
