"Les mille et un fantômes" by Alexandre Dumas is a collection of tales published in 1849. This work presents a series of fantastic stories framed by a central narrative. The author himself appears as narrator, drawn into a mysterious murder case involving a man who claims his beheaded wife spoke to him. This leads to a dinner where guests share increasingly strange tales. Dumas ventures into the supernatural, departing from his historical fiction to explore the shadowy boundary between reality and imagination.
