The next story in the Bibliomysteries series, penned by MWA Grand Master Carolyn Hart. Everyone dreams of stumbling upon a long-lost treasure in the attic or inheriting a fortune from some distant relative. But for Ellen Gallagher, the impoverished owner of a thrift shop in South Carolina, that dream comes true. She finds in her possession a first edition of Agatha Christie's Poirot Investigates that has been signed by the author ... and inscribed to the Queen of England. When the book disappears from her shop, Ellen must call on her friend Annie Darling, owner of the mystery bookstore Death on Demand, to track it down. The Bibliomysteries are a series of short tales about deadly books, by top mystery authors.
