I think this song is about Albert Fish. Read the lyrics to the Grace Budd song. "Kissing his fingers" could be him licking the blood off his fingers. "Saliva bubbling" could be about her in the oven. "The floorboards will never hold the same finish" could be either the blood staining them, or the secret that that house holds. I don't know for sure, but that's just my guess.
