A renowned chemistry professor dies in an explosion in a laboratory. The question quickly arises: Was it really an accident? Markus Trakta, the public prosecutor, is convinced it was murder and has a suspect he wants to bring to justice. But he needs help - and turns to you. The players take on the role of lawyers. In five exciting sections, evidence is sifted through, investigations are carried out and, above all, information is analyzed and evaluated as a team. Together, they decide who seems suspicious and why they should be brought to justice - or whether there are good reasons to prevent exactly that. There are no dice rolls, pawns or playing cards, players will draw their conclusions through discussions and reasoning with one another.
