A reader on a Facebook group (about reading), that I am a part of, has an interesting hypothesis. And I believe there may be some truth to it. Perhaps Harper Lee did not write Go Set a Watchman at all. The style is nothing like To Kill A Mockingbird. The depth of writing is much weaker. And would Lee, writing in the 50s, really have presented Scout as a hard-hearted feminist? With such a deep concern for the racial problems of the day? Reading from a 21st century bias, we see many such characters today. But in the 50s, they just did not exist.
Here is a celebrated author, in a nursing home, with no lawyer-sister here any more to defend and protect her interests, and who is not as lucid as she once was. It might be fairly easy to pull off such a hoax.
It will be interesting to see if this story develops in the days (or years) to come.
