How can anyone have a name like Amadeus? A rather uncool name, thinks Nikolaj, the new student at the music boarding school of Treuenfels. And besides, what is he supposed to be doing here? His father, a famous tenor, went to school at Treuenfels. As if that were a reason to send his son here too! The fact that Amadeus, Fliege, Cosi and Malu try to treat him without reservation is hardly noticed by Niko. He is bored.But then, a violin worth a million dollar is stolen after a major concert, and not long after Niko is a suspect. Amadeus and his friends, the ‚Amadeus gang‘, want to help Niko. But they are drawn into a wild, dangerous chase. For boys and girls aged 9+
