The Most Dangerous Spy

Nancy Brown is an ordinary girl living in the industrial town of Orethorpe at the outbreak of the Second World War.

Seventy years later Arthur Lane is living in Orethorpe. He strikes up a friendship with an elderly man, Mr Smith. When a newspaper reporter turns up asking to interview Mr Smith about his role in the war, Arthur learns that Mr Smith has a deep secret. Can he discover what it is?
