A crime has just been committed. Who is the culprit? What is the motive? Each guest becomes an actor, armed with their powers of observation, their instincts, and a well-filled notebook. Suspects are revealed, clues accumulate, and hypotheses intersect. The castle becomes a playground where mystery lurks around every corner.

A secret scenario for a gradual build-up of tension

The theme of the evening is kept secret until the last moment. This choice reinforces the theatrical dimension of the experience: the dramatic tension builds as the hours pass, unexpected twists and turns captivate the investigators for the evening, and every element of the decor becomes a potential clue. You will find yourself questioning, analyzing, doubting, and above all, collaborating with other participants in a collective spirit.

The atmosphere oscillates between elegance and darkness, perfect for fans of life-size thrillers, but also for those who love theme parties, historical intrigue, or simply those who dream of spending an original Halloween night far from the clichés. This experience is not recommended for those seeking passivity or who are uncomfortable with dynamic social interactions: here, you are at the heart of the action.
