The Purloined Letter is one of Edgar Allan Poe's detective stories. It is the third of the three stories featuring the detective C. Auguste Dupin, the other two being
The Murders in the Rue Morgue and
The Mystery of Marie Roget.
These stories are considered important forerunners of the modern detective story. The method Poe's detective, Dupin, uses to solve the crime was quite innovative. He tried to identify with the criminal and to "think like he would." In May of 1844 Poe wrote to James Russell Lowell that he considered it "perhaps the best of my tales of ratiocination"
