Who is Roberta Cromford, and why is Emily, a florist from Swansea a beneficiary in her will? Having received a surprising letter from a solicitor, the only way for Emily to answer this question is for her to travel to the beautiful North Yorkshire countryside; but her search for an answer uncovers more puzzling mysteries. As she investigates further, she stumbles upon a family's dark past, and finds herself facing financial ruin and the need to find a new source of income - and fast. Not an easy task, especially when combined with the shocking realisation that someone living in your household wants you dead. As Emily becomes increasingly afraid for her life, she still has her greatest challenge to face - the dark, deadly waters of the Striddings; the place where the fear really begins.
