 Novellist R.D. Wingfield (qv), whose "Frost" book were the  inspiration for the series, was very critical of the TV adaptation  and said that it had ruined the character of Jack Frost that he had  created in his novels. The main change between the books and the TV  series is that Frosts prurient and earthy interest in pubescent  teenage girls and young women is much less evident in the TV series.
