Hudson Box Office (HBO) - Luther

Not your usual BBC police series. A self-destructive near-genius, DCI John Luther might just be as dangerous as the depraved criminals he hunts. Luther follows his own moral code as much as the rules of criminal law. But he quickly becomes locked in a lethal battle of wits with Alice, a beautiful, highly intelligent mass murderer, and his decision-making process becomes increasingly murky. Luther's lonely path pulls him towards the very edge of temptation.
Luther is played by Idris Elba who has been nominated for the Golden Globe Best Actor Award three times, winning once.
The library has the first season, consisting of six episodes.
