S1, E4: In Piers Morgan's previous interviews with convicted serial killers, all protested their innocence. Now, for the first time, Piers comes face-face with a serial killer who is willing to admit to his heinous crimes. Over three months in late 1973, 20-year-old Bernard Giles picked up five innocent young women hitchhiking through his neighbourhood, and slaughtered each of them in cold blood. Fortunate to be spared the death penalty, he will never be released from prison.
