Nobody knows exactly what happened in the small town of Klausen, people will say a bomb went off on the autobahn, or at the shack near the autobahn, or someone was shouting at the town from a bridge and it all stems from a fight over measuring noise pollution on the town square, or was it the work of eco-terrorists or Italians. While nobody knows who to blame, they all suspect Josef Gasser, who spent years away from Klausen, is to blame. The town is full of confusion, in a fog of rumour, where everyone claims to know what is happening even if the story changes each time.
