Book excerpt: In his deadliest case yet, Detective Superintendent Roy Grace faces a complex kidnapping in Dead If You Don't, by award winning crime writer Peter James. Now a major ITV series, Grace, starring John Simm. Kipp Brown, successful businessman and compulsive gambler, is on his worst run of luck yet. Taking his teenage son, Mungo, to a football match should have given him a welcome respite – if only for a few hours. But it’s at the stadium where his nightmare begins. Within minutes of arriving at the game, Mungo suddenly disappears and Kipp receives a terrifying message: someone has his child. And, to get him back alive, Kipp will have to pay. Roy Grace is brought in to investigate what seems to be a straightforward case of kidnapping. But, very soon, Grace finds himself entering a dark, criminal underbelly of the city, where the rules are different and nothing is what it seems . . . 'Peter James is one of the best crime writers in the business' – Karin Slaughter, author of The Silent Wife Although the Roy Grace novels can be read in any order, Dead If You Don't is the fourteenth title in the bestselling series.
