Agatha Christie is known as Queen of Crime, and her Miss Marple series is the perfect introduction to the world of cosy mysteries. The Murder at the Vicarage is the first one, which introduces Miss Marple as an amateur sleuth living in the village of St. Mary Mead. A few hours after the local parson makes an offhand remark about how murdering Colonel Protheroe would do the world a favour, the same colonel is found dead. Miss Marple is on the case — but everywhere she turns, someone has a motive to kill this man.
