The sinister, ghostly presence of the mysterious Belphegor is haunting the Louvre, seeking the Treasure of the Kings of France. Against him are pitted the indomitable Chantecoq, the King of the Detectives, and the fearless journalist Jacques Bellegarde. A duel to the death begins between the murderous Phantom of the Louvre and his enemies throughout the City of Lights.

Written in 1927 by Arthur Bernède, the author of Judex, this classic of French criminal literature spawned no less than three motion pictures, one television series and one animated show. This new, unabridged translation by J-M. & R. Lofficier also includes a detailed synopsis of the celebrated 1965 remake starring Juliette Greco.
