Later TV included the part of Stanley Baldwin in "" (1981), and the serials "The Price" (1985) and "Late Starter" (also 1985) in both of which he played angst-filled, middle-aged, middle class characters beset by marital problems in the context respectively of a kidnapping and the early retirement of an academic. Both these series and "Telford's Change" were based on Barkworth's original ideas. In 1988 Barkworth had a leading guest role in the fourth season "Sherlock Holmes" adaptation of the Arthur Conan Doyle story "Silver Blaze." In one of his last roles, he starred opposite his former RADA student Michael Gambon in the 1993 episode "Maigret and the Minister" of ITV's Maigret" series.
