In Greenmantle (1916), a classic tale of espionage and adventure, Richard Hannay, hero of The Thirty-Nine Steps, travels across war-torn Europe on the trail of a German plot and an Islamic Messiah. He is joined by three more of Buchan"s heroes: Peter Pienaar, the old Boer scout; John S. Blenkiron, the American determined to fight the Kaiser; and Sandy Arbuthnot--Greenmantle himself--a character modelled on Lawrence of Arabia. Together they move in disguise through Germany to Constantinople and the Russian border in order to face their enemies: the grotesque Stumm and the evil femme fatale Hilda von Einem.
