I don't know if you've been following the news, but after the announcement that an earlier book of Harper Lee's, a sequel to To Kill a Mockingbird that was actually written first, had been rediscovered, several people came forward to contest her mental competency to consent to publication.
After reading the story, I became very suspicious that the concerned parties actually had ulterior motives. One of them was an author of a new memoir about living next to Harper Lee, and Lee had actually denied having given the author permission to write it. So I figured the woman was either getting her revenge for that, or was trying to generate publicity for her memoir.
The other concerned party was a doctor that supposedly knew her, but had never actually treated her. I wonder if there was a connection between him and the author of the memoir...
Today, however, I saw an article that declares Harper Lee has been found in full possession of her mental faculties. Thankfully this also means that publication of her novel will be going through as planned.
I'm planning on rereading To Kill a Mockingbird soon, so that I'll be ready to read the new book when it comes out. I remember loving Mockingbird when I read it years ago, but it has been a long time and I look forward to rereading it. I don't remember much!
