Detective Constable Rachel Bailey is 30, down-to-earth, noisy, argumentative and single. Her partner, Detective Constable Janet Scott, is 40, a diplomat and a thinker, as well as being a wife and mother. They both work for Manchester Metropolitan Police's prestigious Murder Investigation Team and, despite the obvious differences between them, they make a formidable team.
Rachel steps up to Acting DI on a case that becomes bigger and more sinister than it first seemed. Glad of Rachel's return, Janet couldn't have known how much she was going to need her friend.
When the killers change the rules of their sick game, Rachel's safety is in question. As a police officer, Janet is powerless to protect her daughter but she knows she needs to stop the madness.
As the team makes a significant breakthrough in the case, Rachel's position as Acting DI is jeopardized. Janet's attempt to help Taisie results in a complaint, rocking her faith in justice.
