What are your favourite book theories? I am looking for things hidden in the text, that the author may or may not have intended.
My favourite theory is about Daniel Derona by George Elliot. There is a theory that one of the two principle character, Gwendolen Harleth, was sexually abused by her stepfather, Captain Davilow, and that she was frigid as a result. Given that the book was written in the C19th, that would be quite a bold thing to write about. None of the reviewers from the time seemed to have picked up on it. Captain Davilow was dead before the book started. Nevertheless, the theory would explain a lot.
I didn't find the right solution from the internet.
