In Agatha Christie’s The Body in the Library, the tranquil life of St. Mary Mead is disrupted when the Bantrys discover the body of a young woman in their library. The victim, later identified as Ruby Keene, an 18-year-old dance hostess from a nearby hotel, appears to have no connection to the Bantry household. To prevent scandal and uncover the truth, Mrs. Bantry enlists the help of her astute friend, Miss Marple. As Miss Marple delves into the mystery, she uncovers a complex web of deceit, inheritance motives, and mistaken identities, leading to a surprising revelation about the murderer’s identity.
