Jack the Ripper is a six-part BBC police procedural made in 1973, in which the case of the Jack the Ripper murders is reopened and analysed by Detective Chief Superintendents Barlow and Watt (Stratford Johns and Frank Windsor, respectively).

These characters were hugely popular with UK TV viewers at the time from their appearances on the long-running police series Z-Cars and its sequels Softly, Softly and Barlow at Large.

The series discusses suspects and conspiracies, but concludes there is insufficient evidence to determine who was Jack the Ripper.

The experiment was seen to be a success, and the formula was repeated in 1976 with Second Verdict, in which Barlow and Watt cast their gaze over miscarriages of justice and unsolved mysteries from the past.
