In Greenmantle (1916) Richard Hannay, hero of The Thirty-Nine Steps, travels across war-torn Europe in search 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, modelled on Lawrence of Arabia.
