The Mystery of Marie Roget (often subtitled A Sequel to "The Murders in the Rue Morgue) is another short story by Edgar Allan Poe written in 1842. It again features his character, C. Auguste Dupin as our slightly eccentric detective determined to solve the murder of a young Ms. Marie Roget in Paris.

Her body is found mutilated in the Seine River and the media take a keen interest in the mystery. Dupin remarks that the newspapers "create a sensation... [rather] than to further the cause of truth." Even so, he uses the newspaper reports to get into the mind of the murderer.
