August marks the 50th anniversary of one of Britain's most infamous crimes – the Great Train Robbery. Ronald Biggs was sentenced to 30 years gaol for his part in the crime that he once described as 'too good to refuse'. But behind the robbery and Biggs' subsequent escape to Australia, there's an epic saga of a woman's resilience and loyalty. Disowned by her middle class parents, Charmian Biggs and their two children, followed Biggs to Australia in the hope of a fresh start. It was the beginning of a tumultuous three decades marked by discoveries, escapes, betrayals and reunions. Forced to divorce her husband to help him avoid extradition from Brazil, Charmian Biggs raised her sons on her own and studied to obtain a university degree. She became a successful book editor under the new name of Brent. Then in 2001 Biggs finally surrendered to the British authorities so he could receive medical treatment.
