The Murder at the Vicarage
Agatha Christie
 In St. Mary Mead, no one is more despised than Colonel Protheroe. Even the local vicar has said that killing him would be doing a service to the townsfolk. So when Protheroe is found murdered in the same vicar's study, and two different people confess to the crime, it is time for the elderly spinster Jane Marple to exercise her detective abilities. The vicar and his wife, Leonard and Griselda Clement respectively, who made their first appearance in this novel, continue to show up in Miss Marple stories: notably, in The Body in the Library (1942) and 4.50 from Paddington (1957)
