John Buchan wrote The Thirty-Nine Steps while he was seriously ill at the beginning of the First World War. In it he introduces his most famous hero, Richard Hannay, who, despite claiming to be an 'ordinary fellow', is caught up in the dramatic race against a plot to devastate the British war effort.
