Circular Staircase

Ms Rinehart is considered to be the American equivalent of Agatha Christie. She is the author of the phrase "the butler did it". Rinehart has written hundreds of short stories, plays, travelogues and special interest articles. In The Circular Staircase a spinster aunt and her niece and nephew rent a country house for the summer, not suspecting that a cache of stolen securities is hidden inside the old walls.
