The Last Detective: Series 1 (2003)

He’s gentle, old-fashioned, and decent; nice even when he’s drunk. But these qualities only earn Detective Constable "Dangerous" Davies (Peter Davison) the scorn of his fellow detectives in a small London police station. His boss tells him straight out that he’s the last detective he would assign to a major crime-solving mission. Unlucky in love, rumpled, and accident prone, Dangerous muddles on and, with the help of his eccentric friend Mod (Sean Hughes), he proves the merits of his dogged, unglamorous method. He likes being a detective and, occasionally, he gets to do some good. Based on the Dangerous Davies novels by Leslie Thomas.
