Tatort (Scene of the Crime), Derrick and Ein Fall für zwei (A Case for Two) are three classic crime series on German television. Two of the themes, are from the pen of Klaus Doldinger and the third theme, Derrick was written by Les Humphries, an Englishman, who had great success with the Les Humphries Singers. In Crime Scene Stefan Schwalgin has faithfully adapted the original sound of the melodies to produce a thrilling medley.
