The Extremely Fantastic Theo Miller Gang


The gang (legendary!), the case (criminal!), and other things that can go wrong

It’s the first school day after the break, and Theo Miller overslept. That’s why he’s forced to sit next to Patrick Bartsch, an unpleasant jerk. But Theo has friends. And he forms a gang with them: The Extremely Fantastic Theo Miller Gang. The first battle against evil is not long in coming: A whole classroom set of new iPads has been stolen. And of course, the gang has a suspicion - the unpopular form teacher Mr. Spengler! The observation of their suspect begins ... and ends in a murderously expensive mess. And that’s precisely where Bartsch comes in. Will he expose them? Or does he have entirely different motives?
