Katie Drake was an affluent single mother living in Queen's Park - until someone cut her throat. Worse still, the killer has abducted her fourteen-year-old daughter Naomi. DCI Grant Foster quickly sees chilling parallels to the disappearance of teenager Leonie Stamey three years earlier. With hopes of finding Naomi alive fading, he calls on genealogist Nigel Barnes to piece together the links between the families of the two girls. The trail leads Nigel back to 1890, when a young couple arrived in the UK; a husband and a wife fleeing a terrible crime in their past - and harbouring an awful secret that's now having bloody repercussions in the present .
