There is a London you might not know. A London of dingy, pubs and brutal alleyway encounters; a seedy, seething metropolis populated by weasel-faced burglars, psychotic doormen, and professional killers with cold hearts and cruel intentions. It's a place Matthew Moriarty knows only too well. Jobless, hopeless, and half-crippled following a beating that teaches him not to insult local gangsters and then screw their wives, Moriarty is at rock bottom, left with only an ever-dwindling supply of prescription painkillers for company. And when he takes up a lucrative offer to track down a missing friend, things start to get a whole lot worse. As the search leads Moriarty into mortal danger, to the corrupt heart of the music business, one thing becomes clear: mess with this city, and it messes with you.
