It's a scary mess before Christmas. It's finally that time again. The Advent season begins and the "Liebe" bakery has the most delicious gingerbread. When the three ... come into the bakery, they are surprised: sugar is scattered everywhere and the biscuit cutters are lying around wildly. And that's not all. Who has locked up the old master baker? Is the bakery haunted? Kim, Franzi and Marie are already involved in their next exciting case. Read the detective story for 24 days, solve puzzles and shorten the waiting time until Christmas. Great extra: a poster for colouring by numbers.
