Mrs. Hunt

Mrs. Hunt is the wife of John Hunt and the mother of Hal and Roger. Her first name is never mentioned. While John, Hal, and Roger are on the expedition to the Amazon River, Mrs. Hunt is at the Hunt animal farm when it is set on fire, destroying the entire collection, followed by anonymous threats to burn down the house as well. She sends a radiogram to John, which results in him returning to New York, leaving Hal and Roger to continue the expedition.
