This is the story of the shadowy Intelligence Division of the British War O ffice and its unsung role in the formation of the Victorian Empire and imperial policy making from Asia to Africa. With its focus on the heady days between the Crimean War and the establishment of the MI departments in the early years of the twentieth century, Under Every Leaf tells how Britain was well served by an extensive and sophisticated secret intelligence service which few even knew existed – then or now. Drawing from an encyclopaedic array of primary and little known sources,Under Every Leaf is a rollicking good tale of brains over brawn, adventure, success and sacrifice, craftiness and commitment in the service of the greatest empire the world has ever known.
