The 39 Steps and the Powerhouse

The thirty-nine steps: Richard Hannay, a mining engineer, 'retires' at the age of 37, having made his fortune in Africa. He finds London dull, until he becomes caught up in a sensational plot to precipitate a pan-European war. Hannay is at first disinclined to believe the young American, with his incredible tales of international intrigue, and hints of a terrible secret. But when the American turns up dead in Hannay's flat, Hannay is forced to flee the attentions of both the conspirators and the law. Hannay is hunted across the Scottish moors by police and spy-ring alike, and must outwit his intelligent and pitiless enemy in the corridors of Whitehall and, finally, at the site of the mysterious thirty-nine steps.
