Detective fiction in the English-speaking world is considered to have begun in 1841 with the publication of Poe's "The Murders in the Rue Morgue" itself, featuring "the first fictional detective, the eccentric and brilliant C. Auguste Dupin". The period of the 1920s and 1930s saw a number of writers emerge, mostly British but with a notable subset of American and New Zealand writers. Female writers constituted a major portion of the writers during this period, including Agatha Christie, the most famous, and among the most famous authors of any genre, of all time. Four female writers of the period are considered the four original "Queens of Crime": Christie, Dorothy L. Sayers, Ngaio Marsh and Margery Allingham. Apart from Ngaio Marsh (a New Zealander) they were British.
