Although suspenseful music accompanies this 1952 dramatization, “The Purloined Letter” by American author Edgar Allan Poe lacks the element of horror found in most of Poe’s other short stories. Instead, this is one of Poe’s tales of ratiocination or reasoning, featuring the fictional detective, C. Auguste Dupin. Along with“The Murders in the Rue Morgue” and “The Mystery of Marie Rogêt,” this story is considered an early precursor to the modern detective story.
