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.

Excerpt
My name is Pitman—in this narrative. It is not really Pitman, but that does well enough. I belong to an old Pittsburgh family. I was born on Penn Avenue, when that was the best part of town, and I lived, until I was fifteen, very close to what is now the Pittsburgh Club. It was a dwelling then; I have forgotten who lived there.
