In his classic espionage thriller The Thirty-Nine Steps, John Buchan introduced Richard Hannay, an appealing antihero with the intelligence and daring to thwart a conspiracy involving British secrets and German spies. Greenmantle, the second in Buchan's five-part series of spy novels, reintroduces the intrepid secret agent Hannay. Tasked by the Foreign Office with investigating a rumored uprising in the Muslim world, Hannay and his associates must prevent Germany and its Turkish partners from turning the tide of World War I by launching a jihad against the Allies. Buchan's fast-paced tale of pursuits and escapes takes readers across war-torn Europe and behind enemy lines from Vienna to Constantinople and the Russian front. Written in lean, contemporary prose, this gripping novel offers an action-packed and remarkably topical tale of Middle Eastern politics and intrigue.
