My name is Peter Grant and until January I was just probationary constable in that mighty army for justice known to all right-thinking people as the Metropolitan Police Service (as the Filth to everybody else). My only concerns in life were how to avoid a transfer to the Case Progression Unit — we do paperwork so real coppers don't have to—and finding a way to climb into the panties of the outrageously perky WPC Leslie May. Then one night, in pursuance of a murder inquiry, I tried to take a witness statement from someone who was dead but disturbingly voluable, and that brought me to the attention of Inspector Nightingale, the last wizard in England. Now I'm a Detective Constable and a trainee wizard, the first apprentice in fifty years, and my world has become somewhat more complicated: nests of vampires in Purley, negotiating a truce between the warring god and goddess of the Thames, and digging up graves in Covent Garden... and there's something festering at the heart of the city I love, a malicious vengeful spirit that takes ordinary Londoners and twists them into grotesque mannequins to act out its drama of violence and despair. The spirit of riot and rebellion has awakened in the city, and it's falling to me to bring order out of chaos — or die trying. 

I was my dad's vinyl-wallah: I changed his records while he lounged around drinking tea, and that's how I know my Argo from my Tempo. And it's why, when Dr Walid called me to the morgue to listen to a corpse, I recognised the tune it was playing. Something violently supernatural had happened to the victim, strong enough to leave its imprint like a wax cylinder recording. Cyrus Wilkinson, part-time jazz saxophonist and full-time accountant, had apparently dropped dead of a heart attack just after finishing a gig in a Soho jazz club. He wasn't the first. No one was going to let me exhume corpses to see if they were playing my tune, so it was back to old-fashioned legwork, starting in Soho, the heart of the scene. I didn't trust the lovely Simone, Cyrus' ex-lover, professional jazz kitten and as inviting as a Rubens' portrait, but I needed her help: there were monsters stalking Soho, creatures feeding off that special gift that separates the great musician from someone who can raise a decent tune. What they take is beauty. What they leave behind is sickness, failure and broken lives. And as I hunted them, my investigation got tangled up in another story: a brilliant trumpet player, Richard 'Lord' Grant — my father — who managed to destroy his own career, twice. That's the thing about policing: most of the time you're doing it to maintain public order. Occasionally you're doing it for justice. And maybe once in a career, you're doing it for revenge.  

A WHOLE NEW REASON TO MIND THE GAP It begins with a dead body at the far end of Baker Street tube station, all that remains of American exchange student James Gallagher—and the victim's wealthy, politically powerful family is understandably eager to get to the bottom of the gruesome murder. The trouble is, the bottom—if it exists at all—is deeper and more unnatural than anyone suspects . . . except, that is, for London constable and sorcerer's apprentice Peter Grant. With Inspector Nightingale, the last registered wizard in England, tied up in the hunt for the rogue magician known as "the Faceless Man," it's up to Peter to plumb the haunted depths of the oldest, largest, and—as of now—deadliest subway system in the world. At least he won't be alone. No, the FBI has sent over a crack agent to help. She's young, ambitious, beautiful . . . and a born-again Christian apt to view any magic as the work of the devil. Oh yeah—"that's" going to go well

 Suspicious deaths are not usually the concern of PC Peter Grant or the Folly, even when they happen at an exclusive party in one of the most expensive apartment blocks in London. But Lady Ty's daughter was there, and Peter owes Lady Ty a favour. Plunged into the alien world of the super-rich, where the basements are bigger than the house and dangerous, arcane items are bought and sold on the open market, a sensible young copper would keep his head down and his nose clean. But this is Peter Grant we're talking about. He's been given an unparalleled opportunity to alienate old friends and create new enemies at the point where the world of magic and that of privilege intersect. Assuming he survives the week

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
