[Sherlock] Who is the most famous fictional detective in history?
gpt
There are lots of them. From Britain and Europe we have Agatha Christie's Miss Marple and Hercule Poirot. In the same vein we also have C. Auguste Dupin, a French detective created by the American Edgar Allan Poe.

Going on with the Americans we also have characters like Dashiell Hammett's Sam Spade and The Continental Op, and Raymond Chandler's Philip Marlowe. These are all typical "hard-boiled" characters unlike the other three. Both Sam Spade and Philip Marlowe were portrayed on the silver screen by Humphrey Bogart in *The Maltese Falcon*  and *The Big Sleep*, typifying the film noir genre.
