The Shadow House In the cold and rugged northwest, just off the coast of Washington where Bellingham Bay and Samish Bay intersect, sits a private island owned by reclusive and eccentric millionaire Arthur Denton. Alone on the island for years, the locals know little about Arthur, save for the rumors carried to the mainland. Most have shrugged off the estate's allegations, but not everyone is ready to allow the mystery and murder to remain unsolved. The Haunting of Grant Mansion Mystery and horror surround a long-abandoned estate, seemingly forgotten by the town. So when Callie and Mike move in and begin renovations, the manor seems perfect. However, strange things start to happen in the old house, and soon enough, Callie is forced to deal with some hard truths as she discovers spirits inhabit the house, and they aren't happy with the manor's new occupants.
