The Murders in The Rue Morgue - Themes and Analysis

Themes and Analysis

In a letter to friend Dr. Joseph Snodgrass, Poe said of "The Murders in the Rue Morgue", "its theme was the exercise of ingenuity in detecting a murderer." Dupin is not a professional detective; he decides to investigate the murders in the Rue Morgue for his personal amusement. He also has a desire for truth and to prove a falsely accused man innocent. His interests are not financial and he even declines a monetary reward from the owner of the orangutan. The revelation of the actual murderer removes the crime, as neither the orangutan nor its owner can be held responsible. Later detective stories would have set up M. Le Bon, the suspect who is arrested, as appearing guilty as a red herring, though Poe chose not to.

Poe wrote "The Murders in the Rue Morgue" at a time when crime was at the forefront in people's minds due to urban development. London had recently established its first professional police force and American cities were beginning to focus on scientific police work as newspapers reported murders and criminal trials. "The Murders in the Rue Morgue" establishes an urban theme which will be reused several times in Poe's fiction, in particular "The Man of the Crowd", likely inspired by Poe's time living in Philadelphia.

The tale has an underlying metaphor for the battle of brains vs. brawn. Physical strength, depicted as the orangutan as well as its owner, stand for violence: the orangutan is a murderer, while its owner admits he has abused the animal with a whip. The analyst's brainpower overcomes their violence. The story also contains Poe's often-used theme of the death of a beautiful woman, which he called the "most poetical topic in the world".
