Poe's detective character C. Auguste Dupin and his sidekick the unnamed narrator undertake the unsolved murder of Marie Roget in Paris. The body of Roget, a perfume shop employee, is found in the Seine River and the press takes 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. Dupin uses his skills of ratiocination to determine that a single murderer was involved who dragged her by the cloth belt around her waist before dumping her body off a boat into the river. Finding the boat, Dupin suggests, will lead the police to the murderer."
