"The genius of Edgar Allan Poe extends far beyond his groundbreaking creation of Auguste Dupin, which laid the foundation for detective fiction. What remains little known is that Poe envisioned an even more sophisticated form of the genre. Works in this form take an innovative approach, allowing the reader, rather than a fictional detective, to uncover and solve hidden murders.

These stories reflect his ambition to engage readers in a game of wits with himself. This study endeavors to rise to his challenge and unravel the perfect crimes--hidden for nearly two centuries--within these tales. As we delve deeper, another mystery arises: "What is analysis?"
