Bloodlust

In the North German region, some people are disappearing without a trace. They seem to have vanished into thin air. Kiel appears to be a particular focus in this case, as the majority of people have disappeared from the immediate area. The police are puzzled because the victims don't seem to have any commonalities. There have been numerous calls from the police to the public to remain vigilant and report all incidents, even if they seem completely insignificant. However, no clearly usable hints or clues have emerged from this. Some leads led to a certain "Michael von Grafenstein". The police thoroughly investigated and interrogated him. But he seems utterly beyond reproach. No criminal records, no problems with his neighbors, he's never even improperly parked his car. He appears to be a businessman, traveling a lot. However, he consistently attends mass at his church congregation every Sunday. You are private investigators. The family of a missing person wants to finally have certainty and has commissioned you to scrutinize all the suspects again. So, you stand at the door of Mr. von Grafenstein, who seemingly is again away on a business trip. Your mission - should you choose to accept it: Search Mr. von Grafenstein's apartment and verify if he really has nothing to hide. Hopefully, he won't come back while you're turning his apartment upside down...
