DCI Christine Caplan

In the village of Cronchie, a wealthy family are found brutally murdered. The Devil Stone, an heirloom rumoured to bring death if removed from their home, is the only thing stolen. The key suspects are known satanists. But when the investigating officer disappears, DCI Christine Caplan is pulled in to investigate. Caplan knows she is being punished for a minor misdemeanour when she is seconded to the Highlands, but she's confident she can quickly solve the murders and return home to her fractious family. But as she closes in on the truth, it is suddenly her life that is in danger.

'Girl A' was convicted of murdering three people when she was a child. Now she's missing and a man is dead. The top brass are screaming for a quick resolution, and Girl A is a media sensation and a risk to herself as well as others. The clock is ticking for DCI Christine Caplan to bring her to justice - but the truth may be darker than even she fears . . .

A dying cop asks DCI Christine Caplan to fulfil her last wish: to investigate a cold case that’s still preying on her mind. The naked body of a young man that was found in a lonely wood, dismissed as a down and out by her superiors. Caplan connects the case to other victims left to die in the bleak Scottish forests, injured and unable to escape. As the scent grows stronger, the cold cases suddenly seem dangerously hot.
