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
The city turned its dreariest aspect toward the railway on blackened walls, irregular and ill-paved streets, gloomy warehouses, and over all a gray, smoke-laden atmosphere which gave it mystery and often beauty. Sometimes the softened towers of the great steel bridges rose above the river mist like fairy towers suspended between Heaven and earth. And again the sun tipped the surrounding hills with gold, while the city lay buried in its smoke shroud, and white ghosts of river boats moved spectrally along.
