In the spring of 1892, Frank G. Lenz, a gallant young accountant from a modest German American family, set forth from his unhappy home in Pittsburgh to circle the globe atop a new 'safety' bicycle with inflatable tyres (the forerunner of today's road bike). He brought along a large wooden camera and arranged to send regular reports to his sponsor, Outing magazine, effectively making him a harbinger of the great bicycle boom that was about to explode with stunning social and industrial repercussions. Two years, fourteen thousand miles and many adventures later, after crossing the United States, Japan, China, Burma, India and Persia, just as he was about to enter Europe for the home stretch, Lenz vanished. His presumed murder in Asiatic Turkey jolted the American public and became an international cause celebre. The Lost Cyclist recounts, for the first time ever, the short but remarkable life of Lenz and the heroic efforts of another American 'globe girdler', William L. Sachtleben, who was sent by Outing to unravel Lenz's mysterious death in Turkey - all set against the horrifying backdrop of the Hamidian massacres.
