Just when DI Tom Mariner seems to be settling down with his new girlfriend...everything kicks off. First, a badly decomposed body of a young woman is found in a Birmingham sewer. The police can't identify her and dub her "Madeleine". Then, an important politician and his wife are shot on an isolated road. "Vengeance is mine" is scrawled in blood at the scene. Finally, a bomb explosion in the busy city kills five people, causing chaos and panic. Can Detective Mariner and his team get to the bottom of crimes that will come very close to home for him and his team?
Two teenagers go missing on the same day. Just a coincidence? They are from very different backgrounds: Yasmin is the talented, grammar-school-educated daughter of devout Muslim professionals. Ricky disappears after storming out of his council house after an argument with his mum's latest boyfriend. The press is convinced Yasmin's disappearance is a racially motivated abduction. Her family has been the target of a far-right group. But DI Mariner soon discovers Yasmin is far from the innocent victim her parents think she is.
DI Tom Mariner thinks he's seen it all, but now he faces an investigation which will push him to the limit. Journalist Eddie Barham is found dead in his home. A syringe in his arm and a note by his side reading, "No More". Open and shut case of suicide? Not for DI Mariner. Hours before, he saw Barham picking up a prostitute in a bar. And then Mariner discovers Barham's younger brother, Jamie, hiding in a cupboard under the stairs. Mariner is determined to connect with Jamie and get to the truth.
