"Luther" is a psychological crime drama starring Idris Elba ("The Wire") as Detective Chief Inspector John Luther. In the first programme, Luther, back from suspension, must find the person responsible for a double murder. The format of the show was inspired by American crime drama "Columbo" in that viewers are shown the identity of the criminals but do not know how they will be caught. The series sees a welcome return to the small screen of Paul McGann as Mark North, and also stars Warren Brown as DS Justin Ripley. It premiered on BBC One in 2010.
