The Thirty-Nine Steps

The Thirty-Nine Steps by John Buchan (1915)

Richard Hannay, a bored mining engineer, stumbles into an international espionage conspiracy and must flee across the Scottish Highlands with both the police and enemy agents on his trail. The novel that invented the modern spy thriller.

Historical Significance:
John Buchan, a Scottish politician and future Governor-General of Canada, wrote The Thirty-Nine Steps in 1915 while recovering from illness during World War I. The novel created the "man on the run" thriller template: an innocent man is framed, pursues the real villains while being pursued himself, and must solve the mystery to clear his name. Alfred Hitchcock's 1935 film adaptation is one of his greatest works. Every spy thriller from James Bond to Jason Bourne follows the structural template Buchan established.
