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
By the bequest of an elder brother, I was left enough money to see me through a small college in Ohio, and to secure me four years in a medical school in the East. Why I chose medicine I hardly know. Possibly the career of a surgeon attracted the adventurous element in me. Perhaps, coming of a family of doctors, I merely followed the line of least resistance. It may be, indirectly but inevitably, that I might be on the yacht Ella on that terrible night of August 12, more than a year ago.
