Eric Enno Tamm knew he had problems from the beginning. With access denied to China, he nonetheless set out to retrace Baron Carl Gustav Mannerheim's footsteps from Russia to China a century before, and encountered more than just this first obstacle along the way. He chronicles both his journey and Mannerheim's in his new book The Horse That Leaps through Clouds - one that Wade Davis says "reveals him to be at once an intrepid adventurer, fine writer, and discerning historian." Keep your ear to the ground for an upcoming Speakeasy episode with Eric, and in the meantime, find out more about the book here.
