Query: Dickens' mind was falling apart

This is an exceptionally lousy book from Dickens. I read it and understood the words, but I didn't understand anything. It seems like there is no coherence in the book. The numerous characters are just babbling away on their own account, and I couldn't discern any logical progression of a plot. This is the last novel completed from Dickens, I seriously believe he was growing crazy or something at this point, or maybe his mind was just decomposing and falling apart?
