"The Mystery of Marie Rogêt", often subtitled A Sequel to "The Murders in the Rue Morgue", is a short story by American writer Edgar Allan Poe written in 1842.

[1] Poe's detective character C. Auguste Dupin and his assistant, the unnamed narrator, undertake the unsolved murder of Marie Rogêt in Paris.

The body of Rogêt, a perfume shop employee, is found in the Seine, and the press takes a keen interest in the mystery.

In the story, Dupin explains that "it is the object of our newspapers rather to create a sensation—to make a point—than to further the cause of truth",[citation needed] and proceeds by exposing the contradictions in their theories.

Dupin rejects the popular theory blaming the murder on a gang of ruffians seen in the area around the time of Rogêt's disappearance.

An "editor's note" states that it would be inappropriate to relate details of what followed, but that the police did apprehend the true murderer with the help of Dupin's deductions.

As Poe wrote in a letter in 1842: "under the pretense of showing how Dupin ... unravelled the mystery of Marie's assassination, I, in fact, enter into a very rigorous analysis of the real tragedy in New York.

Although there was intense media interest and immortalizing of a sort by Poe, the crime remains one of the most puzzling unsolved murders of New York City.

The newspaper reported new evidence that suggested that Rogers, the real-life victim, may have died from a botched abortion attempt, referred to as a "premature delivery".

The characters neither move nor speak.... Only a professional student of analytics or an inveterate devotee of criminology can read it with any degree of unfeigned interest.
