Ghosts of Paris: Mona Lisa Murder Mystery Puzzle Walk
Follow a dead woman's trail through Paris's darkest streets and solve the case that history never closed.
This Paris murder mystery puzzle walk reconstructs the haunting true story of L'Inconnue de la Seine, a young woman pulled from the river whose serene death mask later became the face of Rescue Annie, the CPR training dummy kissed by more people than any other face in history.
Starting at the Arc du Carrousel and tracing the riverbanks of the Seine, each puzzle stop connects a real Paris landmark to a layered web of ghosts, crimes, and centuries-old secrets. Audio narration accompanies every clue, grounding the fiction in documented history.
The route visits nine of the city's most charged locations, including the Palais de Justice, Sainte-Chapelle, and Notre Dame's gallery of stone kings. The experience works best after dark, when the atmosphere of each site shifts considerably.
Played entirely through the Questo app at your own pace, this walk requires no guide, no fixed schedule, and no prior knowledge of Paris. The difficulty is rated easy, though the subject matter is intended for adults.

Route Overview
The walk begins here, at the ornamental arch that once marked the entrance to Napoleon's palace. This is the departure point before the trail descends toward the Seine.
The site where the unidentified young woman's body was discovered with an expression so composed it prompted decades of speculation. The first clues are decoded here.
Two of Paris's most historically loaded buildings sit side by side on the Ile de la Cite. Puzzle clues at this stop draw on the island's long role as the seat of French justice.
The cathedral's facade features a gallery of 28 stone kings, each a clue point in the investigation. The Red Man of the Tuileries also resurfaces here.
The route passes through a street with a documented history of violent deaths, disappearances, and one particularly grim legend involving a barber and his clientele.
The last stop brings together all collected evidence and closes the investigation with a conclusion that connects the fictional case to its real historical roots.
