Aboard a ship, the protagonist of "The Dead City" writes a letter to his fiancée, whom he has abruptly abandoned just days before their wedding. In it, he recounts the eerie events experienced alongside Henri d'Herauville, a French novelist, close confidant, and former fiancé of Francinette. The narrator describes reuniting with his friend at the port of city "C" and wandering through the crumbling ruins of an old colonial town. There, inside a mysterious subterranean cavern that sparks foreign curiosity, the unthinkable unfolds.
