Are you a fan of police investigations and theatrical plays that are a little out of the ordinary? Starting October 3rd, The Kergorlay-Langsdorff Hotel, a unique hotel in the 16th arrondissement, invites you to experience something unusual. With SIGMA, The Immersive Investigation, you'll play detective to uncover the assassin hiding among the actors, all while being a ghostly spectator.
A Closed Room in 1950s Paris
Step into the Paris of 1958, right at the heart of the Sigma Club, a very exclusive association that brings together individuals with high intellectual potential. In a private hotel, a meeting takes place to celebrate the return of Pierre Kessler, one of the founding members of the club, just released from prison after being cleared of murder charges related to Lina Floyd, an employee at the British embassy.

A Theatre Where the Audience Solves the Mystery
Unlike a classic play—filled with stages, backstage areas, and velvet curtains—in this immersive show, it’s you who makes the choices in the storyline. At the heart of a mysterious crime unfolding throughout the rooms of the Kergorlay-Langsdorff Hotel, you are free to follow the characters’ actions and listen to their secrets. But be careful: don’t trust everyone! Some won’t hesitate to lie, manipulate, and lead you down false paths.
An experience lived from within, filled with subtle clues, twists, and new revelations, where you piece together the plot by choosing your own journey. All that’s left for you to do is: find the pieces of this grand puzzle, separate the truth from the lies, and of course, unmask the killer.
