When Dodie Blackstock, only child of multi-millionaire Wolf Blackstock, is told that her mother¿s body has been found in a housing estate in Hackney, she is shocked. When she is told that her mother, Susan, has been dead for less than 48 hours, she is devastated. For Susan was kidnapped, apparently by a politically motivated group, when Dodie was eight. Susan was never found, and she was presumed dead.

Traumatised by her lonely childhood, Dodie has been estranged from her dysfunctional and complicated family for years. She returns to Camoys Hall, the Blackstocks' stately home, to talk to her stepmother Joan, who lives there by herself. But Dodie finds more than she bargained for - and then she starts to receive anonymous and threatening letters. Who is waiting in the darkness outside Camoys Hall, watching her every move . . . ?
