A TOUCH OF FROST is a television detective series produced by Yorkshire Television for ITV from 1992 until 2010, initially based on the Frost novels by R.D. Wingfield. It stars David Jason as Detective Inspector William Edward Jack Frost. Frost, known almost universally as Jack, is an experienced and dedicated detective who frequently clashes with his superiors. In his cases. Comic relief is provided by Frost's interactions with the bureaucratically-minded Superintendent Norman Mullett, played by Bruce Alexander. The series is set in the fictional South-Midlands town of Denton, and is marked by a gritty tone. It is believed that Denton is in Oxfordshire, with many references to Reading, Oxford, and in particular, Swindon, especially in the earlier episodes, as the M4 and A417 are often seen, and the map of Swindon was seen in the control room, although a map of Reading was used occasionally.
