Mary Roberts Rinehart (1876-1958) was considered the American Agatha Christie, and The Circular Staircase was her first bestseller. It tells the story of spinster Rachel Innes, who along with her adopted niece and nephew, are challenged by strange crimes, including murder, in a house they have rented for the summer.
