Helton Hall in Dial-a-Ghost by Eva IbbotsonRead about the other entries on the list.
What if you are a home-loving spirit, but you have lost the house you were supposed to haunt? A family of five, the Wilkinsons die after a second world war bomb falls on their house. Now of no fixed abode, these ghosts meet two elderly sisters who run a charity for displaced ghosts. Before long the kindly Wilkinsons are relocated to Helton Hall…but there’s been something of a mix-up. A witty, ghoulish comedy of errors.
