Gordon Goody is the mystery man of the Great Train Robbery, the most notorious theft in British history. Regarded by his partners as tough and fearless, he has kept his silence for five decades. Until now. Raised in rural Northern Ireland, Goody served as an army sergeant but chose a life of crime and became one of the most professional and prolific robbers in London. He and his gang were offered the job of a lifetime: details of a Glasgow to London mail train laden with cash, provided by The Ulsterman, whose identity Goody reveals for the first time.
