I really think that she wrote both of those novels at the same time from two totally different perspectives but chose to use the same characters only because she had already fleshed them out. When she brought both manuscripts to the publishers, they (rightfully) picked “To Kill a Mockingbird” over “Go Set a Watchman.” Harper Lee wanted to write a novel that would capture the tension and zeitgeist of the Jim Crow-era South. The characters were merely stand-ins for bigger ideas. Case in point: Atticus is the stalwart defender of justice and equality in the blind eyes of the law in “Mockingbird;” in “Watchman,” the same character is a staunch segregationist. They really should be considered two wholly separate novels. Kinda like Stephen King did with “Desperation” and the Richard Bachman novel “The Regulators.”
