When a woman is found dead in Edinburgh, the scene unsettles DCI Belinda Brennan in a way she cannot quite explain.
The victim appears unremarkable, yet the brutality of her death suggests something deeply personal. As Brennan begins to dig, she uncovers a trail that leads far beyond a single murder and into a web of past betrayals, buried secrets, and long-held resentment.
At the centre of the case is Helen King, a damaged young woman shaped by abuse, addiction, and abandonment. Fresh from withdrawal and desperate to stay clean, Helen has returned to confront the ghosts of her past. But old wounds are dangerous, and the pull of revenge can be stronger than any drug.
As more bodies are discovered, Brennan realises she is not just hunting a killer. She is confronting a lifetime of silence and failure that allowed one woman's pain to fester into violence.
With time running out, DCI Brennan must decide how far she is willing to go to stop a killer forged by betrayal, before more lives are lost.
