Well shit, you're right. But c'mon this wasn't her decisionIn February 2015 at age 88, nearly blind and deaf after a 2007 stroke, and after a lifetime of maintaining that she would never publish another novel, Lee released a statement through her attorney confirming publication of her second novel, Go Set a Watchman, written before To Kill a Mockingbird, which was released in July 2015.
The story I heard is she wrote this first then someone said the flashbacks were better than the main story and she scrapped it, writing To Kill a Mockingbird. Then her literary agent or attorney found this manuscript and got an invalid to sign off on the publication after refusing to do so for sixty years. There's also the story that Truman Capote wrote To Kill a Mockingbird as a gift to her as they were childhood friends. I'm only mentioning that because I think it's interesting. "It really makes you think," isn't an argument but I'm sure this book will create all sorts of theories and counter theories to that literary conspiracy.
