Book excerpt: Soldier, explorer, mystic, guru, and spy, Francis Younghusband began his colonial career as a military adventurer and became a radical visionary who preached free love to his followers. Patrick French’s award-winning biography traces the unpredictable life of the maverick with the “damned rum name,” who single-handedly led the 190 British invasion of Tibet, discovered a new route from China to India, organized the first expeditions up Mount Everest and attempted to start a new world religion. Following in Younghusband’s footsteps, from Calcutta to the snows of the Himalayas, French pieces together the story of a man who embodies all the romance and folly of Britain’s lost imperial dream.
