A search for the lost city of the Musus took intrepid Bob Moran, ex-spitfire ace, into the province of Mato-Grosso in the heart of Brazil. It was there that Colonel Fawcett had disappeared, searching for the lost city and the legendary mines of the Indians. The savage Morcegas and Chavantes Indian tribes stand between Bob and his goal. In the lost city further dangers arise from the predatory Paez brothers, intent on exploiting the mines. This jungle adventure echoes with the feeling of antiquity and plunges from one crisis to the next. Bob is the crisp clean-cut type of hero who laughs boldly in the face of peril and befriends the weak. Vivid and exciting for teen aged boys.
