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. Linden Hills (novel)
Linden Hills is a novel written by Gloria Naylor, originally published in 1985.
 Naylor bases her allegory on Dante's Inferno.
 The narrative is written from a third-person omniscient perspective, detailing different characters based on different traits that correspond with the different rings of Dante's interpretation of Hell.
 The novel is a revision of Naylor's Yale master’s thesis. List of works by Dorothy L. Sayers
