In his classic bilingual style, Joe tells the story of a haunted house in a poor little town in Arizona. Even when the landlord offers free rent, nobody moves in because they know a ghost lives there. That is, until Elena's father rents it. He doesn't believe in ghosts. Lucky for Elena that her grandmother knows all about the ways of ghosts. She helps her solve the mystery of the "ghost on the roof" while Elena learns a very important lesson about life.
