Mary Roberts Rinehart (August 12, 1876-September 22, 1958) was a prolific author often called the American Agatha Christie.[1] She is considered the source of the phrase "The butler did it", although she did not actually use the phrase herself, and also considered to have invented the "Had-I-But-Known" school of mystery writing.

The Bat (1920) was a play first, then got turned in a movie and this novel. It is one of Rinehart's most popular mystery stories.
