The true tale of John Henry Patterson, the Victorian adventurer who set out to build a bridge over the Tsavo River -- and later became a game warden in Kenya. The production of the bridge turns out to be a monumental task when two man-eating lions hunt and kill much of the work force. Written at the turn of the 20th century, it's a baffling story, much in the tradition of the period's classic works of exploration and adventure in Africa.  (EAF80, $18.95)
