Dupin: The Murders in the Rue Morgue

Dupin: The Murders in the Rue Morgue is a browser-based, choice-driven, AI-generated adaptation of Edgar Allan Poe's 1841 story, and the first of five cases for C. Auguste Dupin.

Paris, July 1840. Two women are dead in a fourth-floor room locked from the inside, and the neighbours who heard the killer each swear the voice spoke a different language. You play Dupin, the reclusive amateur who takes the Prefect's money and none of his methods, and you decide what to examine, whom to question and how to draw the truth out with a notice in the newspaper.

Cases 2 and 3 retell Poe's other two Dupin tales (The Purloined Letter of State, The Mystery of Marie Rogêt). Cases 4 and 5, The Automaton of the Palais-Royal and The Revenge of Minister D., are new stories in the spirit of the canon, not adaptations of anything Poe wrote. This listing covers the series; case 1 plays without an account, and the cases after it need a free sagaflow.ai account.

How it is made: every scene of the text is generated by AI. A language model wrote each case's opening when it was set up and writes the rest, with its options, while you play, so nothing is written by hand. Cover art, narration and music are AI-generated as well. The team made the game systems and picked the stories.

You choose from a few options per scene, and from your fourth decision you may type your own move, twice per case. A case runs about ten scenes.
