When several young prostitutes are found murdered in Liverpool, DI Leigh Moss knows there is only one person she can turn to for help with the case. Gangland queen, Grace Carter, knows the streets of Liverpool better than anyone and can ask questions Leigh can’t…but will Grace help?
Grace doesn’t trust easily, but when she discovers that her family might be linked with the gruesome murders, she decides to give Leigh a chance. But helping Leigh is risky and as Grace is dragged deeper into the murky world of vice, her own life is put in danger.
Can these two sworn enemies work together? Or is that a line they will never cross?
