The von Artle Legacy

Note: I would classify this as paranormal, but there is no such category listed. I do not believe in ghosts, but something very strange was going on then. It has been more than 30years, and I still have no solid answers. The von Artle Legacy is based on a true experienceA woman inherits a small lush island in Florida. When she and her computer expert husband move in they find there are ghosts. Two in the main house and one in the servants quarters house where Tom is setting up his computer business.
The ones in the main house are friendly and welcoming. The one in the comp house is most definitely not!
