The Inside Man (1969)

The Inside Man, produced by Derek Granger and David Cunliffe, offers more of a reimagining than a direct replacement of its predecessor's concept. The series features Frederick Jaeger as Dr. James Austen, a psychiatrist and criminologist who alternates between working for Basil Henson's character, Dawnay, from "the Department," and taking on cases from private clients. Petra Davies plays Sarah Worth, Austen's dependable 'girl Friday.' In the third episode, *Crosscheck*, Robin Ellis joins the cast as Michael Barnett, a spy whom the Department insists Austen should approve. However, every detail about Barnett is an obvious fabrication, adding layers of intrigue to the storyline.
