Rodney D. Wingfield originally wrote the book Frost at Christmas in the
1970's, but failed to get it published. Instead he turned it into a
radio play starring
Leslie Sands as Jack Frost. The book was finally
published in 1982 and has been followed by A Touch of Frost (1987),
Night Frost (1992), Hard Frost (1996) and Winter Frost (2000). In 1992
ITV began the dramatisations of his books starring
David Jason in the
lead role, but owing to the complex nature of his novels and the many
different sub-plots in them, one novel became the basis of up to three
television stories. Wingfield has never watched the series in case it
influences his novels.
