Patrick Quentin, Q. Patrick and Jonathan Stagge were pen names under which Hugh Callingham Wheeler (19 March 1912 – 26 July 1987), Richard Wilson Webb (August 1901 – December 1966), Martha Mott Kelley (30 April 1906–2005) and Mary Louise White Aswell (3 June 1902 – 24 December 1984) wrote detective fiction. In some foreign countries their books have been published under the variant Quentin Patrick. Most of the stories were written by Webb and Wheeler in collaboration, or by Wheeler alone. Their most famous creation is the amateur sleuth Peter Duluth. In 1963, the story collection The Ordeal of Mrs. Snow was given a Special Edgar Award by the Mystery Writers of America.
