The Appleton Case

"In Derbyshire, Janet and Joan have just purchased a small bed and breakfast, Doveby House, but Janet finds herself doing her own investigating.
Just how did the previous owner, Margaret Appleton, die?
Margaret's son isn't happy that he was left out of his mother's will, but what's he so desperate to get inside Doveby House to find? And are there really ghosts in Janet's bedroom, the library and the coach house?"
