Luther Series 3: What we know so far.

I am beyond excited by the forthcoming return of BBC1's crime drama Luther. Details of this third series are virtually non-existent, but the details that have trickled out are mouth-wateringly good.

• We know Luther will be back for Two 2-part stories totalling four episodes.

• We know from BBC drama commissioner  Ben Stephenson that the first episode is 'terrifying' 

• We know all of the main cast from series 2 including Warren Brown and Dermot Crowley.

• We know Sienna Guillory (Resident Evil, Inkheart, Love Actually, Eragon) has been cast to play Luther’s new love interest

• And possibly the most exciting bit of news to do the rounds about the new series is the confirmation of the return of the wonderful Ruth Wilson as the delightfully devilish Alice Morgan.

                                        Luther Series 3 is expected in Summer/Autumn 2013 on BBC1
