The Boo Radleys are fictional characters from the novel To Kill a Mockingbird by Harper Lee. They live in the small town of Maycomb, Alabama, and are often the subject of local gossip and children's imaginations. The family is reclusive, particularly the mysterious figure of Boo Radley, who is rarely seen outside their home. Throughout the story, the children, including Scout Finch and her brother Jem, are both frightened and fascinated by the Radleys. As the plot unfolds, they learn valuable lessons about empathy and understanding, ultimately discovering that Boo is not the monster they imagined, but a kind and protective figure.
