As resident Mark Twain thrills the ghost walk crowd with stories of the paranormal and long ago murders, he didn't quite expect a dead body to turn up in the middle of a tour. The victim has two knives stuck in his back…the same two knives used in previous murders, which were on display at the museum house. One of the tourists on the ghost walk is an old girlfriend of Andrew's and she's been charged with the crime. Can Raine and Andrew prove her innocence? And can they corral an old flame of the accused named Pinball who wants to crack heads? Plus Daisy, our chimp hostess, has learned sign language…nothing can go wrong there!
