The Tombstone Detective Agency - Who's Got Our Ghosts?

Kent's Ghosts are vanishing. Why? How? Who's responsible? Ghost Girl Tessie intends to -find out; especially as her Aunt Gertrude's disappeared. As the Board For Ghostly Behaviour is about as much use as a leaky umbrella, Tessie and her super sleuth friend, Alex, (not a Ghost, but friends support each other, right?) will have to turn private investigators themselves. Aided by an eccentric group of local spooks, Alex and Tessie are determined to solve the Mystery of the Disappearing Ghosts. Will they succeed?
