37x28 - Scene of the Crime

It should look like an accident. But Prof. Boerne's autopsy findings are clear: the well-known clairvoyant Roswitha Brehm was murdered. Just a few hours before the crime, she had desperately tried to contact Inspector Thiel. Did she want to solve a crime again using a pendulum? Thiel is skeptical. But now the clairvoyant died in the mysterious villa that had already made big headlines in Münster. Years ago, almost the entire Steinhagen family was shot here. The case went unpunished and the bodies were never found. Only the adopted daughter Franziska survived the bloodbath. Is there a connection between the clairvoyant's death and the murder of the Steinhagens?
