Andy McNab’s life reads like a fiction novel. He was abandoned at birth, raised by the cleaner, has almost every gallantry award the military can give, is producing a musical in New York, has worked with Robert de Niro - and was diagnosed as a psychopath. In part two, the SAS veteran tells Gary Jubelin what it’s like living as a functioning psychopath.   Get episodes of I Catch Killers a week early and ad-free, as well as bonus content, by subscribing to Crime X+ today.
