Faced with two false confessions and numerous suspects after a despised civil magistrate is found shot in the local vicarage, Detective Inspector Slack reluctantly accepts help from Miss Marple.
Amateur detective Miss Jane Marple investigates the murder of a young woman whose body is found in the library at Gossington Hall, home of Colonel and Mrs. Arthur Bantry.
Mr. Jason Rafiel asks Miss Marple to solve a crime but, he does gives her any details. In fact, he can't be sure that a crime was committed at all.
