Book 7 in the Rivers of London series, from Sunday Times Number One bestselling author Ben Aaronovitch.

In London, the past is never dead. It only lies sleeping...

Martin Chorley - aka the Faceless Man - wanted for multiple counts of murder, fraud and crimes against humanity, has been unmasked and is on the run. Peter Grant, Detective Constable and apprentice wizard, now plays a key role in an unprecedented joint operation to bring Chorley to justice.

But even as the unwieldy might of the Metropolitan Police bears down on its foe, Peter uncovers clues that Chorley, far from being finished, is executing the final stages of a long-term plan. A plan that has its roots in London''s two thousand bloody years of history, and could literally bring the city to its knees.

To save his beloved city Peter''s going to need help from his former best friend and colleague - Lesley May - who brutally betrayed him and everything he thought she believed in. And, far worse, he might even have to come to terms with the malevolent supernatural killer and agent of chaos known as Mr Punch...
