The Unknown Woman of the Seine - VR Mystery Hunt

A 360 Mystery Hunt in time & space

About the project

In this one-of-a-kind game, mixing outdoor Mystery Hunt and flashbacks into the Belle Epoque period (1900) thanks to Virtual Reality, your mission is to find all the hidden clues and finally solve the mystery of the Unknown Woman of the Seine.

Go back in time to solve a genuine investigation! 100 years ago, a woman was found drowned on the Île Saint-Louis in Paris. Who was this mysterious woman? Was it a murder? Who are the other strange characters? Is the killer hiding among them?

It's your turn to investigate!

Based on a true story. 

The Unknown Woman of the Seine was a famous story in Europe in the early XXth century. It inspired French song writer Serge Gainsbourg for his song "La noyée" ("The drowned woman").

A woman was found dead nearby the river Seine in Paris. Her face and her intriguing smile inspired numerous literary and artistic works. The newspapers tried to find who she was but no one ever identified her. They name her "The Unknown woman of the Seine". We imagined a new story about this inquiry and what may have happened...

The protagonists:

How does the game actually take place ?

  • join us on the Île Saint-Louis for an hour and a half hour game (date at your convenience from September)
  • we give you the "investigator kit" : Virtual Reality headset ; headphones ; map of the island ; Sémaphore
  • discover the history of Île Saint-Louis 
  • walk around in search of real and "virtual" clues:

at specific locations, use the free gift Virtual Reality headset to view 1900 scenes as if you were there... and solve the mystery!

Example on the right: the free gift headset will be used with your own smartphone that will serve as a screen. The specially designed videos will allow you to watch the scene by turning your head in all directions... ie 360 degrees.

View the first 360 sequence of the game:

NB: On YouTube, click on the "HD / settings" icon on the screen to select the best quality.
You can watch this video with a Virtual Reality headset, but also on your computer (use the keypad or arrow keys to move) or with a smartphone (move the image by touching the screen or by moving the phone).

About the project owner

This project started when a mystery hunt creator met with VR professionals and decided to join forces to offer you this unprecedented experience.

Inspired by Back to the Future or Cluedo, our idea was born years ago from a dream to create an immersive Mystery Hunt in the heart of Paris. The rapid evolution of Virtual Reality made the dream come true.
