Lies Sleeping

The seventh book of the bestselling Rivers of London series returns to the adventures of Peter Grant, detective and apprentice wizard, as he solves magical crimes in the city of London.
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 him to justice.
But even as the unwieldy might of the Metropolitan Police bears down on its foe, Peter uncovers clues that the Faceless Man, 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....

Ben Aaronovitch was born in London in 1964 and had the kind of dull routine childhood that drives a man either to drink or to science fiction. He is a screenwriter, with early notable success on BBC's legendary Doctor Who, for which he wrote some episodes now widely regarded as classics, and which even he is quite fond of. After a decade of such work, he decided it was time to show the world what he could really do, and embarked on his first serious original novel. The result is Midnight Riot, the debut adventure of Peter Grant.
