Angela Murphy has just started as a detective on the mean streets of Glasgow, when the mutilated corpse of a young prostitute is discovered in a squalid apartment.

Called to investigate the grisly murder, Angela is both shocked and surprised. To her boss, Frank Martin, there’s something horribly familiar about the scene. He has seen it before.

With limited resources and lacking experience, Angela is desperate to prove herself. But is it really the work of a copycat killer, and will Angela’s enthusiasm and determination be enough to bring the killer to justice before another life is lost?
