Mockingbird
Harper Lee published one book, and never published another.
That’s genius? She had only one book inside of her, and then once she let it out she was finished for good and there was no reason to write another.
Or maybe she had writer’s block and couldn’t write another.
I remember reading once that she gave an interview claiming that she’d finished a second novel (finally!) but someone broke into her home and stole it. I thought that it was improbable that she didn’t have another copy.
Maybe that story is true, but also maybe it’s true that Harper Lee didn’t think she needed to write anything else.
