Not to take us far afield of our topic of
The Hobbit, but the info on Tolkien's sequel to
LOTR is here...
Tolkien gave us some hints about the Fourth Age that Christopher Tolkien brought to light in his volume
The Peoples of Middle-earth in the chapter
The New Shadow.

He called, but there was no answer. He halted in the narrow passage that ran through the house, and it seemed that he was wrapped in blackness: not a glimmer of twilight of the world outside remained there. Suddenly he smelt it, or so it seemed, though it came as if it were from within outwards to the sense: he smelt the old Evil and knew it for what it was.
The capital letter ‘E’ on Evil tells us, I believe where Tolkien was going to go with his sequel. Oh what kind of tale would it have been had he finished it!!??
