In 1925 Colonel P. H. Fawcett embarked on a journey into a dangerous and largely unexplored region of Brazil in search of a fabled lost city and was never seen again. Journalist Peter Fleming's interest in Fawcett's disappearance led him to answer an advertisement to join an expedition to explore the rivers of Brazil with the aim of ascertaining the explorer's fate. Though Colonel Fawcett's disappearance remains a mystery to this day, Peter Fleming's wild adventure in the jungles of Brazil is recognized as one of the 20th century's best-loved travel classics.
