It should look like an accident. But Prof. Boerne's autopsy results are clear: the well-known clairvoyant Roswitha Brehm was murdered. A few hours before the crime, she had desperately tried to contact Inspector Thiel. Did she want to solve a crime by pendulum again? Thiel is skeptical. But now the clairvoyant died in the mysterious villa, which had already made big headlines in Münster. Years ago, almost the entire Steinhagen family was shot here. The case went unpunished and the bodies could not be found. Only the adopted daughter Franziska survived the bloodbath. Is there a connection between the psychic's death and the Steinhagens' murder?
