Ravenhurst Manor

Charles Ravenhurst built the 53-room manor house on a high cliff overlooking the oil town of Bartlesville, Oklahoma. After Charles and his family died mysteriously within its limestone walls it was abandoned for many years until Charles' only surviving relative John was located. John and his wife Brandy decide to solve the mystery of the violent deaths, but after moving in they soon discover that the house is just as mysterious as the deaths. During their exploration of the house and grounds they discover the family crypt which hides the entrance to an underground tunnel leading to a circular room full of what appears to be straight off the bridge of the USS Enterprise. If it's a control room, what does it control and who else knows of its existence? At least one person knows, and he is determined to own the house no matter what it takes -- even if he has to kill John and Brandy to obtain it. Fortunately the house has other ideas.
