After the morning news broke, one message is on everyones lips: Murder in popular Cafe Cle. Tracking down the murderer seems impossible, they are a ghost, with details of the crime baffling all - despite forensic evidence, witness statements and renowned investigators on the case. Speculations throughout the whole of Germany abound: Is this the „perfect murder“? Is it truly an unsolvable case?! Your team cannot and will not accept this, you are taking over the case! For together, you are the best investigator team in Europe... Who, if not you, will manage to make sense of the crime. You will gather evidence, evaluate witness and suspect statements, search for a motive and above all, remain determined to find the perpetrators... but, is everything really as it seems?
