In Greenmantle (1916), Richard Hannay, hero of The Thirty-Nine Steps, travels across war-torn Europe in search of a German plot & 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; &, Sandy Arbuthnot, Greenmantle himself, modelled on Lawrence of Arabia. The intrepid four move in disguise through Germany to Constantinople & the Russian border to face their enemies: the grotesque Stumm & the evil beauty of Hilda von Einem.
