Dorothy L. Sayers: Dorothy Leigh Sayers ( ; 13 June 1893 – 17 December 1957) was a renowned English crime writer, poet, playwright, essayist, translator, and Christian humanist.  She was also a student of classical and modern languages.

The Wimsey Papers: The Wimsey Papers are a series of articles by Dorothy L. Sayers published between November 1939 and January 1940 in "The Spectator".  They had the form of letters exchanged by members of the Wimsey Family and other characters familiar to readers from the Lord Peter Wimsey detective novels, but were in fact intended to convey Sayers's opinions and commentaries on various aspects of public life in the early months of the Second World War, such as black-out, evacuation, rationing and the need of the public to take personal responsibility rather than wait for the government to guide them.  The subjects range from very practical and detailed advice on such issues as how pedestrians can avoid being hit by cars in black-out to quite Utopian and far-reaching schemes for the post-war reconstruction of Britain.

The Silent Passenger: The Silent Passenger is a British black-and-white mystery film produced in 1935 at Ealing Studios, London.  This was the first film outing for novelist Dorothy L. Sayers' fictional amateur sleuth Lord Peter Wimsey.  It was based on an original story written by Sayers specifically for the screen.  Her amateur sleuth was portrayed as a somewhat eccentric imbecile who solved murders in spite of himself.

Murder Must Advertise: Murder Must Advertise is a Lord Peter Wimsey mystery novel by Dorothy L. Sayers, published in 1933.  Most of the action takes place in an advertising agency, a setting with which Sayers was very familiar.  One of her advertising colleagues, Bobby Bevan, was the inspiration for the character Mr Ingleby.

The novel is a revision of Naylor's Yale master’s thesis.
