Greenmantle (Version 3)

Richard Hannay, the hero of The Thirty-Nine Steps, is pulled back into the shadows of espionage when British intelligence intercepts whispers of a German plot to ignite revolution across the Islamic world. With the Great War grinding toward its bloody climax, Berlin's strategists have uncovered a weapon more dangerous than any torpedo: a fanatical holy man called Greenmantle, whose mere presence could rally millions to rise against the Allied powers. Hannay must cross enemy lines, navigate the treacherous streets of Constantinople, and reunite with the enigmatic Sandy before the Germans can unleash their religious weapon at Erzurum. What follows is a pulse-pounding race through a world where empires crumble, faith is weaponized, and every shadow might conceal a traitor. Written in 1916 when the war's outcome still hung in the balance, Greenmantle captures the breathless anxiety and moral certainty of a generation fighting for civilization itself. It remains a landmark of the spy genre, blending adrenaline-fueled adventure with unsettling questions about how easily religion can be bent to power's will.
