In Birmingham they love the Gov'nor, boo hoo ooo
Now we all did what we could do
Now Watergate does not bother me
Does your conscience bother you?
Tell the truth
UPDATE: The denouement of Go Set A Watchman is somewhat disappointing. After finding out that her fiance and her father (and uncle) are closet (or not so closet) racists, Scout confronts her Dad, telling him she wants to leave Maycomb and never come back. That would probably have been a good move on her part.
Why? Because she realized that she would never fit into Maycomb's incestuous society (literally - the book makes note that everyone in town is married to a second cousin). She cannot marry her fiance -and does not. She could, however, make a new life for herself in New York, where she is happier and more productive and could achieve greatness.
Instead, her Dad talks her out of it, claiming that Maycomb and the South "need good people" like her to set an example for others, which in some perverse way is going to fix the racism of the South. And Scout agrees with him and settles in Maycomb for the rest of her life as a spinster.
Sadly, art reflects real life. Harper Lee ended up moving back to Monroeville Alabama, which eventually became a "Mockingbird" tourist trap in her honor (and she had to sue the town for royalties from sales of Mockingbird merchandise). Whether her presence changed the attitudes of anyone in Alabama is debatable. Well, not really, given how things are going in Alabama these days. It is still at the bottom of the heap in America, right up there with Mississippi.
And as I noted before, she never went on to write anything else. She sacrificed her life and career on the altar of "family" to appease her Father and relatives and the sensibilities of her neighbors. Maybe she was destined to be a one-trick pony. It is hard to say. But I am not sure that anyone has a "duty" to return to their jerkwater small town just because Dad says so.
In fact, it is a pretty shitty idea.
