Taking a break from London, regency widow Lily Adler arrives in rural Hampshire with her friends, the Carroways, hoping to spend time with her charming new acquaintance, Matthew Spencer. Hearing that a ghost resides in Belleford Manor, Lily and her party decide to visit, only to find that the matriarch of the family has just been found killed in her bed. Lily is determined to learn the truth—but in this third case (after Silence in the Library), could she be next in line for the Great Beyond?
