The arrest and trial of the "most famous Soviet spy of all time", Rudolf Abel, is the inspiration for the latest Steven Spielberg blockbuster, Bridge of Spies. But who was Abel and what is the story behind his unlikely upbringing as a grammar school boy in the north-east of England?
"Red spy nabbed" screamed the Pathé News broadcast of October 1957 as Rudolf Abel was marched away in handcuffs.
It was the archetypal Cold War tale - an undercover operative arrested after his cover was blown.
Spared the electric chair, Abel was sentenced to three decades in prison. But just over four years later he would be handed over in return for Gary Powers, an American apprehended by the Soviets when his U-2 plane was shot down in 1960.
