A Fife teacher only realised the extent of her father’s secret life while watching a hit movie starring Benedict Cumberbatch.
Sherlock star Cumberbatch, 38, plays Alan Turing, the man behind the Second World War Enigma project in the movie, The Imitation Game.
Primary school teacher Jane Smith, 54, from St Andrews, went to see the film knowing her dad, John Harrison, had been involved in code-breaking during the war.
But she was unaware he was part of such an exclusive team, whose heroic exploits inspired the film.
Jane said: “It was only when I watched the film with my husband, Blair, last week that the final pieces of the jigsaw fell into place and we truly realised dad’s contribution to the war.”
