A gripping new outing in London for PC Grant in the SUNDAY TIMES bestselling series from Ben Aaronovitch. Doctor Who Screenwriter Ben Aaronovitch's superbly entertaining supernatural crime series has, with its witty one-liners and wonderfully erudite take on London, won a legion of fans in double quick time. Peter Grant is learning magic fast. And it's just as well - he's already had run-ins with the deadly supernatural children of the Thames and a terrifying killer in Soho. Progression in the Police Force is less easy. Especially when you work in a department of two. A department that doesn't even officially exist. A department that if you did describe it to most people would get you laughed at. And then there's his love life. The last person he fell for ended up seriously dead. It wasn't his fault, but still. Now something horrible is happening in the labyrinth of tunnels that make up the tube system that honeycombs the ancient foundations of London. And delays on the Northern line is the very least of it. Time to call in the Met's Economic and Specialist Crime Unit 9, aka 'The Folly'. Time to call in PC Peter Grant, Britain's Last Wizard. Ben Aaronovitch is the author of the Sunday Times bestselling PC Peter Grant series of novels (Rivers of London, Moon Over Soho, Whispers Under Ground, Broken Homes and the upcoming Foxglove Summer). He was born and raised in London, and his love for the city is reflected throughout the series. Ben has also previously written for television and worked as a bookseller. He still resides in London, and is currently working on his next novel.
