Reply To: The rest of the story: what happens after the lyrics end in Creepy Doll?
I think the money absolutely *is* in the fireplace. Just like how vampire movies are really about buried sexuality and robot movies are really about fear of the dehumanizing effect of technology, the "big city money" is a reference to an outsider coming to a small-town community and being devastated by all the secrets that are held there. By burning the money along with the box, the protagonist is losing both his previous social identity as well as mind.
In my YouTube video, I've got the doll escaping as soon as she's driven the protagonist crazy enough to burn the box, at which point, *he* becomes the doll and tries to ensnare the next victim. Nothing in the song which indicates any of this, but it makes for a very satisfying, genre-fulfilling ending to the video.
