This is sort of a touristy little version of a fascinating historical case. It might make a nice souvenir from a local gift shop, but it won't satisfy any serious reader or tackle any of the important questions the story raises. Were any contemporary accounts of the haunting published at or near the time? (Apparently not, unfortunately). Did Andrew Jackson really visit the Bells? What record exists that he did? (In fact, the evidence to substantiate this seems to be lacking). You can find a great deal more hard information on this extraordinary episode on any of several websites. The attempt to link the ultra-colorful and complex personality of the spirit known as Kate to some lights flickering in a cave near the site today is especially dubious.
