It was 1993, and Englishwoman Sam Gillingham was facing the heartbreaking prospect of being an orphan at the age of 24. She had escaped a turbulent home life in a seaside resort on the south coast of the U.K. eight years before, after her mother had vanished in strange circumstances. But now she was informed that her father had also gone missing. Dad had apparently fallen from a boat out at sea and was now feared drowned. However, when police investigated further, a terrible truth began to emerge, and Sam now faced a possibility even more appalling than merely being orphaned.
