"Natasha Blake is a detective with a difference. She's an ancestor detective, an ambitious young genealogist with a passion for history, whose choice of career is partly driven by the mystery of her own roots. The disappearance of a young girl, Bethany, appears to be linked in some way toLizzie Siddall, the haunting, ethereal Pre-Raphaelite model and artist, whose life was cut short by an overdose of laudanum. Was it accident or suicide? Why is Bethany so obsessed with her, and at the same time so determined to put herself beyond the reach of her lover, Adam?"
