Set in Florida's Everglades National Park, this is the story of a Henry Albert Bunks, a tenement child, who finds release in the thriving life of the swamps. At first Henry's trips into the Everglades simply form a background for escape fantasies, but when he finds his pet alligator skinned, a terrible anger grips Henry which catapults him actively into the mature business of the park. Infuriated by the activities of a poacher with whom he finds employment, Henry is instrumental in putting an end to the culprit's activities but as he finds an effective outlet for his anger he also finds within him the seeds of adult compassion. A sensitive depiction of a young boy's development mingles here with a vivid and full portrayal of the one tropical park on the mainland of the United States. Written for a younger age group than the other books in this series.
