Go Set a Watchman is a novel by Harper Lee published on July 14, 2015, by HarperCollins in the United States and William Heinemann in the United Kingdom. Although written before her first and only other published novel, the Pulitzer Prize-winning To Kill a Mockingbirdand initially promoted by its publisher as a sequelit is now more widely accepted as an earlier draft. The title comes from Isaiah 21:6: "For thus hath the Lord said unto me, Go, set a watchman, let him declare what he seeth." It alludes to Jean Louise Finch's view of her father, Atticus Finch, as the moral compass ("watchman") of Maycomb, and has a theme of disillusionment, as she discovers the extent of the bigotry in her home community.
