Author Harper Lee sues literary agent for copyright of 'To Kill a Mockingbird'

Harper Lee, the author of the book To Kill a Mockingbird, is suing a literary agent for the copyright of her book.

Lee, 87, says literary agent Samuel Pinkus tricked her into transferring the right to the book by taking advantage of her failing sight and hearing, according to BBC News.

The lawsuit says that when Lee’s former literary agent Eugene Winick became ill in 2002, Pinkus' company took over several of Winick’s clients without paying for royalties. Pinkus is Winick’s son-in-law, BBC News reports.

Pinkus allegedly did not respond to several license requests surrounding the book, according to BBC News.

The reclusive author, who lives in Monroeville, Ala., and rarely responds to interview requests,  published her Pulitzer Prize-winning book in 1960, BBC News reports. Since then, To Kill a Mockingbird has become a classic piece of literature and has sold more than 30 million copies. It is read in schools across the nation as assigned reading.

To Kill a Mockingbird is the story of two children whose father is a lawyer defending a black man wrongly accused of raping a white woman in Depression-era Alabama.

The novel is the only book Lee has ever published, according to BBC News.
