Haunted House - Jack Kilborn, J.A. Konrath
This book had a completely different ending than I thought it would. I love a good ghost story, even though there *may* be something else going on here. It seemed to me that they mixed in a little bit of Silence of the Lambs (the character of Torble reminded me of Hannibal), House on Haunted Hill (because of the million dollar reward for spending the night), and Thirteen Ghosts (I don't think there were 13 ghosts in this house but they had similar names). Basically, it's pretty much what you expect from a horror novel.
