As a murder detective in the Met Police, D.I. Matthew Denning is used to seeing the very worst of humanity. But when the mutilated body of a young woman is found in an East London churchyard, her face beaten beyond recognition, he is plunged into his most disturbing case yet.

The victim, petty criminal Bryony Allen, has plenty of secrets – but nothing that seems to justify the cruelty of her death. Until Denning, and D.S. Molly Fisher, uncovers a link between her murder, the execution‑style killing of two men in a derelict Kent hotel, and the disappearance of an undercover officer inside a high-level criminal gang,

While the top brass want to suppress Denning's discovery, the team knows that the key to the case may lie in the actions of a rogue officer. And when his own boss, D.C.I. Liz McKenna, vanishes without a trace, the investigation turns terrifyingly personal...

A twisty, utterly compelling London detective thriller that fans of Angela Marsons, Mark Billingham and BBC's 'Line of Duty' will love.
