Can you unmask the murderer?
It's the 4th of November 1948. A murder has been committed in the Twannbach gorges and you've been called in to solve the case.
During this investigation tour, you'll have to take on the role of a real police superintendent and investigate a fascinating criminal case, all set against the spectacular backdrop of the Twannbach gorges. Clues to help you solve the crime will be communicated to you by characters played by an actor. The enigma will finally be revealed in Twann, over a glass of fine Lake Biel wine. The scenario is based on a detective novel by the Swiss author Friedrich Dürrenmatt, whose story took place in the same place.
