One murder, three families destroyed
And a detective guilty of a crime of her own

When 18-year-old Ben Renshaw is found dead in city woodland, DCI Robin Lyons is plunged into one of Birmingham's most controversial cases.

Months earlier, Ben and his best friend gave testimony that sent a former classmate, Alistair Heywood, to prison for a vicious sexual assault. Before the trial, the boys and their families endured months of brutal witness intimidation, for which the Heywoods, a privileged and influential local family, faced no legal repercussions. Instead, they vowed revenge.

Is Ben's murder the fulfilment of that vow, the beginning of a bloody new chapter that will go on claim lives on all sides? Or is the truth - as the Heywoods claim - something entirely different?

To solve the case, Robin has to negotiate the city's networks of power while walking a dangerous line: her own daughter, Lennie, has a secret that could threaten her liberty - and, if it comes out, Robin's, too. Before long, Robin comes to question whether she knows what justice is at all.
