A Touch of Frost is a detective television series produced by Yorkshire Television for ITV in the United Kingdom.
It stars Sir David Jason as Detective Inspector William Edward Frost, GC, known as Jack to everyone but his late wife (after the 1st episode). He is experienced and dedicated to his work, but he is always clashing with his superiors, mainly represented in the series by Superintendent Norman "Horn-rimmed Harry" Mullett, played by Bruce Alexander. The two have highly incompatible personalities. Mullett is an ambitious buttoned-down by-the-book administrator, and Frost is a down-to-earth "street copper". Nonetheless, they appreciate each other's professional abilities.
On 15 September 2008, it was announced that A Touch of Frost will be concluded in 2009 after 17 years, following David Jason's decision to retire the role.
