Miss Willoughby and the Haunted Bookshop DVD

Meet Miss Willoughby (Nathalie Cox). Orphaned as a child, raised by a family friend (Kelsey Grammer) and skilled in strategy, literature and martial arts, there's no mystery she cannot solve. But even she is baffled when a long-time friend tells her that a ghost is haunting the bookstore that she runs.

Is someone playing a trick on the poor woman? Is it an hallucination? Or is something more sinister going on?
