Who will investigate? Take your class on a criminal hunt between the Baltic Sea and Lake Constance! A cheeky gang of seven credit card fraudsters is on the loose across Germany. Their nimble fingers don't even spare the wallet of Police Chief Bingo's mother-in-law. And even Kugelblitz gets robbed! It's clear that the likable commissioner won't let this slide! Together with his colleagues from Hamburg and other federal states, he is hot on the gang's trail. From the Baltic Sea to Lake Constance, from Leipzig to Xanten, your students will travel the country with Kugelblitz. It’s helpful to be familiar with maps and timetables!.
