The author of To Kill A Mockingbird has sued a literary agent she says tricked her into assigning him the copyright on the Pulitzer Prize-winning book.
Harper Lee, 87, says Samuel Pinkus took advantage of her failing hearing and eyesight to transfer the rights and has failed to respond to licence requests.
To Kill A Mockingbird was published in 1960 and is considered a classic. It has sold more than 30 million copies.
Lee is rarely seen in public and declines almost all interview requests.
