Simon Pegg and Nick Frost are helping to bring this to television.

"Simon Pegg and Nick Frost's production company, Stolen Picture, is set to adapt Ben Aaronovitch's fantasy novel, Rivers Of London.

"We were in a position where I said ‘there’s this book that I loved’ and it became available, more or less," says Frost in an interview with Deadline. "I was chuffed to bits that I could get the rights to make it into a TV show. Everyone wants to potentially find the next Game Of Thrones and the chance to turn Rivers Of London into an eight-hour movie and hopefully find someone who will financially back that is a real draw.”"
