A Touch Of Frost: Marc Warren Playing a Psychopath (Paying the Price S4E1)

Marc Warren played dangerous psychopath Graham McArdy, in this intense episode of Frost, and engaged in a game of cat and mouse with Frost. This episode along with Widows and Orphans (S2E2) and Penny For The Guy (S5E1) are 3 times when A Touch of Frost really dropped the ''whodunnit'' format and made it clear who the criminal was and more about a game of cat and mouse between Frost and the criminal. I wouldn't have minded if they had done this format more often
