Atticus Finch is not a real person. He is a character in a novel. While he may be multifaceted and dynamic as a character, he is that and only that—a character, comprised of the requisite parts given him by Harper Lee when she wrote the consummate American novel, To Kill a Mockingbird and also when she wrote the first draft of that novel, which is now known as Go Set a Watchman.
For in fact, that is exactly what Go Set a Watchman is—a first draft, the initial disorganized and somewhat plotless musings of a slightly younger Harper Lee than the one who wrote Mockingbird. Miss Lee's publisher, HarperCollins, has done the business of promoting Watchman as if it were an entirely separate novel—because that is what their identity is; they are a business. As much as we would like to think of publishing houses as being run by noble, educated persons who are nearly super-heroes in their defense of great literature, the truth is, HarperCollins is a business organized for the purpose of making money. Lots and lots of money.
And so it seems they have done with Watchman. (It is currently number one in literature/classics on Amazon.) But while they touted this book as 'a new novel by Harper Lee,' those good folks know exactly what this is; it is the first pages of a novel written by a young college student who thought she might like to write about the South, her hometown, and her father. In Watchman, she characterizes Atticus as having caved to the agenda of the racists of his town. In Mockingbird, he stands against such folk. Which Atticus best reflects Amasa Coleman Lee, Harper's real-life father? Who can say, and we will never know, as our beloved Miss Lee, always reticent to give interviews, is now beyond the point of discussing either novel.
When I wrote Tainted Legacy, a book about my great-grandmother, Bertha Gifford, who is now vilified as a serial killer, I wrote the original draft to fit the current True Crime genre. After long discussions with a publisher who read that original draft, however, I decided to rewrite the book as a memoir. Now it is a book that I am quite proud of, as it reflects a wider scope of Bertha's story (which is also my grandmother's story and my mother's and mine as well). In the same way, I believe Harper Lee had similar discussions about her first go at a novel, and she came away with some ideas about how she wanted to change her portrayal of this character, Atticus Finch, and the town of Maycomb... and herself. Thus she produced the much beloved work we know today as Mockingbird. If only she'd had the presence of mind to toss that first manuscript in the incinerator... as I have done with my first attempt.
