Greenmantle

Richard Hannay is back, and so is trouble. It's 1916, the Great War grinds on, and a German plot to ignite Islamic holy war against the British Empire has set Europe ablaze with a new kind of danger. A mysterious Islamic prophet called Greenmantle could rally Muslim populations across the Middle East, threatening everything the British hold dear. Hannay, joined by two daring companions, must track the conspirators from London to the shadowy streets of Constantinople and beyond, into landscapes where empires crumble and fanatics dream of holy war. John Buchan writes with the verve of a man who knows that some dangers come not from bullets but from faith twisted into a weapon. This is adventure fiction at its pulp-wicked best, dripping with exotic locales, shadowy villains, and the kind of breathless momentum that made Buchan the king of the pre-WWII spy thriller.
