Geronimo Stilton - Un sorbet aux mouches pour Monsieur le comte

In the dead of night, Geronimo receives a call from his cousin Trap, which sounds a lot like an S.O.S.
No sooner said than done! Just enough time to gather Thea and Benjamin, his sister and nephew, and off they go on a train, heading for Transratania. There, they quickly find Trap, who has been hired as a cook in a castle that seems to terrorize the entire region. It must be said that the inhabitants of the sinister house look very much like vampires…

Geronimo, Thea, and Benjamin try, in turn, to get hired at the castle to rescue Trap, who doesn't feel in danger at all. One day, Count Vlad Von Sourizek organizes a grand ball.
It's the perfect time to uncover the castle's secrets…
