Vienna, 1788. Not everything is as glamorous as it seems at the Burgtheater, and secret information is being passed on unnoticed. Will the players uncover the traitor?

Together, they arrange the 24 pieces of the story in the correct order to solve the case.

The free Ravensburger Echoes app is required to play. In the listening mode of the app, players can play the sounds. In the solving mode, players check the order of four cards at a time to solve chapter by chapter. Finally, players must arrange the entire story in the correct order to solve the case.
