Los crímenes de la calle Morgue
In writing the series of Dupin tales, Poe capitalized on contemporary popular interest. His use of an orangutan in "The Murders in the Rue Morgue" was inspired by the popular reaction to an orangutan that had been on display at the Masonic Hall in Philadelphia in July 1839. In "The Mystery of Mary Rogêt", he used a true story that had become of national interest.
