There are Such Things - Leonard Low - Bog

While the Weem Witch was going to print, Lenny would take lectures about the pittenweem Witches inside the medieval tower where it all took place.
During a tour, 16 people witnessed an apparition, it stood in view and was photographed by one of the party, 8 years later of study, "there are such things" is written documenting poltergeist activity, and written by those who have witnessed the "thing" photographs inside give it credibility with newspaper accounts and TV coverage adds to a strange tale.
The tower has stood for 400 years, whatever walks the tower floors, walks alone.
