Luther has returned for season five on the BBC.
The drama brings a gritty realism to the Beeb, and it looks like this season will give us more of the same.
Luther takes to the underbelly of the criminal world as he tries to solve the worse crimes.
Idris Elba, who stars as John Luther, described the four-parter as "classic".
We already know Alice (Ruth Wilson) is back, the psychotic woman became close with the DCI in season three.
We were told she was murdered off screen in season four, but she returns for season five.
The show is based in London, which means fans have been keeping a beady eye out for familiar spots.
