The Mockingbird Next Door (2014) by Marja Mills is a memoir chronicling her close relationship with reclusive author Harper Lee and her sister Alice Lee. Based on interviews and time spent living next door to them in Monroeville, Alabama, the book offers an intimate portrait of their private lives, exploring their Southern roots, complex family dynamics, and guarded views on fame, writing, and personal identity. Mills respectfully navigates sensitive topics such as Harper Lee’s literary silence after To Kill a Mockingbird, her strained friendship with Truman Capote, and persistent public misconceptions, all while reflecting on the emotional depth of biographical storytelling.
