The Thirty-Nine Steps, Paperback

When a strange man turns up on his doorstep with stories of spies and assassinations, Richard Hannay is drawn into the murky world of international espionage. Four days later, the stranger is dead and Hannay is caught up in a dramatic race to prevent a world war. Hunted across Britain by enemies unknown, he must outwit his pursuers and try to reach the site of the mysterious "Thirty-Nine Steps."

John Buchan is best remembered for his adventure stories and in particular the five Hannay novels, which include Greenmantle, The Three Hostages, and The Island of Sheep.
