The coastal crime novel now in large print. Just before Police Chief Thies Detlefsen falls into a depression from boredom in Fredenbüll, (criminal) life comes to the little town. Three bank robbers raid a branch in the neighboring village of Schlütthörn, a hostage dies, and the perpetrators flee. Thies and his colleague Nicole Stappenbek don't know where to start their investigation. They have no idea that the big showdown will take place in the Fredenbüll Edeka market and that fish sandwiches will play a vital role.
