Klaus Löwitsch cultivated his image as a lone wolf with this series. As private detective Peter Strohm, he investigates in numerous cases with espionage background. Often there is a foreign connection and the series is therefore set at airports, hotels and company headquarters. For German television, this series and its high production budget was completely new at the time. Sometimes the role models from US television are achieved. If not, it's at least involuntarily funny. In any case, a nostalgic trip into past TV decades.
