Barlow at Large is a British television programme created by Troy Kennedy Martin and Elwyn Jones. It broadcast from September 1971 to February 1975, with a total of 29 episodes across four series. Stratford Johns reprises his role of DCI Charles Barlow from Z-Cars, Softly, Softly, and Softly, Softly: Taskforce. Barlow at Large originated as a three-part self-contained spin-off from Softly, Softly in 1971 with Barlow co-opted by the home office to investigate police corruption in Wales. Johns departed in 1972, but returned for a further series of Barlow at Large in the following year, Barlow having gone on full-time secondment to the Home Office. In 1974, the series was rebranded Barlow and two further series of eight episodes each followed, introducing DI Tucker. After the finale's transmission in February 1975, Barlow was next seen in the programme Second Verdict in which he, alongside a former colleague, investigates unsolved cases and unsafe historical convictions.
