The syndicate have taken everything from her. It’s time to take them down—or die trying.

DCI Kate Young never meant to shoot Superintendent John Dickson at the reservoir that night—even if, as a scheming corrupt cop and head of the shady syndicate, he probably had it coming. But now Kate has photographic evidence that someone else knows her terrible secret…

Tormented by guilt and the voices of the dead, Kate is desperate to unmask the rest of the corrupt officers before her own sins catch up with her. When DI Harriet Khatri, awaiting trial for the murder of Kate’s mentor, claims she was framed by Dickson’s syndicate, Kate reluctantly agrees to help in the hope of finding answers.

Meanwhile, DI Emma Donaldson finds herself on the hunt for a double murderer—a man who incapacitates his victims with a powerful narcotic called Devil’s Breath. Desperate to measure up to her role-model boss, Emma finds herself hurled into the deep end in more ways than one…

While Kate’s grip on reality wavers and the syndicate closes in, and with the mystery killer taking a special interest in Emma, could this be the case that defeats both detectives?
