On May 7, 2001, Ronnie Biggs arrived in Britain for the first time in about thirty-five years. His return was the end of one of Britain's most famous crime stories, The Great Train Robbery. In 1963 Biggs was in a gang that stole £2.6 million from a train traveling between London and Glasgow. The gang was caught quickly, and Biggs was sentenced to thirty years in jail. Many people thought that the sentence was too harsh(严厉的). Biggs also thought it was too harsh, so he decided to escape.

Biggs was sent to Wandsworth Prison, a maximum security jail. It had one very high wall to keep the prisoners in, and some guards to watch them. One afternoon in July 1965, Biggs was in the prison yard. He had been in jail for just fifteen months. A tall van(货车) stopped outside the jail, and a ladder was placed against the wall. Then a rope ladder was thrown over the wall into the prison yard. Biggs climbed up the rope ladder, jumped down into the van and escaped!

From that time on, Biggs lived on the run. After hiding in France, Spain and Australia, he finally settled in Brazil in 1970. He was a celebrity(名人) criminal. He appeared in rock videos and movies, and he sold souvenirs to tourists who came to see him. But he missed his home in Britain and, at the age of seventy-one, decided to go home. He was met at the airport by family, friends—and police.
