Mysteriet på Greveholm - Grevens återkomst

The Christmas calendar takes place sixteen years after the Olsson family moved in. The ghosts Jean and Staffan now live alone at Greveholm. The castle has been in disrepair for some time, but when a new family moves into the castle, the ghosts are happy to finally have some company. The ghosts want to do everything to make the family happy in their new home, but it soon turns out that the castle harbors far more secrets than anyone previously thought.
