A Mysterious Halloween Investigation at MSJ

This year, Halloween is coming to the Château de La Tour-de-Peilz with “Uncle Théophraste’s Haunted Legacy,” a mystery game specially created for the occasion byAtelier Sémaphore.

You play as a small family that has just inherited an old house following the death of a somewhat strange great-great-uncle. A nice surprise? Not quite… No sooner have you settled in than you discover that your new home is indeed haunted!

Strange occurrences are piling up, and something seems to be trying to communicate with you. Armed with your investigation notebook, explore the different rooms of the house, gather clues, and solve a series of puzzles to figure out what’s going on there.

Over the course of eight stages combining observation, logic, hands-on activities, and coded messages, you’ll gradually uncover the story of Theophrastus and the mysterious creatures that inhabit this place. But are they really as unsettling as they seem?

Inspired in part by Celtic folklore and the ancient festival of Samhain, this adventure combines investigation, mystery, and magical creatures in a Halloween atmosphere that the whole family can enjoy.
