Not long out of the fast-track training course at Edinburgh's police college, Detective Sergeant Carla Herron is about to be tested to breaking point.
She's been called to Deepwell psychiatric hospital in the Scottish borders to interview a patient who has confessed to the murder of one of the hospital's psychotherapists. The confession is vividly detailed, but for a man locked in a secure ward and under 24-hour surveillance, it is also utterly impossible.
So why can't the supposedly murdered psychotherapist be contacted? Why are the hospital staff so secretive, so difficult to work with? Why have other Deepwell patients made disturbingly similar confessions over the past year? Against the advice of her superiors, Carla delves deeper into the hospital's past and is plunged into a labyrinth of jealousies, lies and hallucinations.
Struggling to separate fact from fantasy, Carla embarks on a chilling trail through the bleak uplands and dark forests of the Scottish borders, every step taking her closer to a final – deadly – reckoning.
