“I realised that I was bottled as sure as a pickled herring, and that there was only one way out. I had to die. If my pursuers knew I was dead they would go to sleep again.”
Richard Hannay returns to England from South Africa to start a new life, but he gets caught up in a plot to ruin the British war effort (the First World War). Soon Hannay has to flee from his pursuers and has to fight for his life while trying to reveal the cipher code that will uncover the plot.
