'Girl A' was convicted of murdering three people when she was a child. Now she's missing and a man is dead. The clock is ticking for Scottish detective DCI Christine Caplan to bring her to justice - but the truth may be darker than even she fears . . . When a body is discovered in the water at Connel Bridge, the police assume it's an open-and-shut case of suicide. But when DCI Christine Caplan is called in to take a closer look, she discovers that darker truths lurk beneath the surface, and suspicion begins to turn to a young woman recently out of care. Known only as Girl A, her identity remains anonymous, protected under law.
