If this whole saga was a fight between good and evil, then who had won? As far as Miriam could work out, neither good nor evil had triumphed yet. Now she was having to confront the grim consequences of Will's behaviour, and she was mortally afraid. Maybe he and his darkness would win after all. The tragic suicide of a young student starts a shocking chain of events for William Marshall, his wife Miriam and their son, Ollie. As Will descends into madness, a ghostly presence appears in their old house to protect Ollie. However, when two strangers threaten Miriam and an attempt is made to snatch Ollie, mother and son are forced to flee. Amidst ever-present danger, they shake off pursuers to seek sanctuary in Rock House in Dorset, where they meet Caitlin and her friends. Twenty years have passed since Charlie Bond helped Caitlin solve the mystery of her mother's death. Now, it is the turn of Charlie's sidekick, Sam Haskell, to investigate a mysterious cult and unmask a killer.
