The first teaser trailer for Luther season five looks suitably mean and moody

"This will hurt."

If any of John Luther's previous adventures are anything to go by, it most certainly will. Having survived the kind of rogues' gallery that Batman would be at least mildly intimidated by up to this point, Idris Elba's long-suffering (seriously, give the guy a holiday or something) detective is back once again. Almost. The long-awaited return of the hit BBC show is nearly with us, and the Beeb have released the first official look at Luther's current state of mind, body, and soul... https://www.youtube.com/watch?v=4qQCMfKDfLo Really puts the 'tease' in 'teaser trailer' doesn't it? And no official release date, either. Cheers, lads. So, what do we we know so far? An official plot synopsis from earlier in the year promises that:

"The moonless shadows of London give birth to a new nightmare. DCI John Luther must once again confront the depths of human depravity. As a series of monstrous killings becomes ever more audacious, Luther and new recruit D.S. Catherine Halliday are confounded by a tangle of leads and misdirection that seems designed to protect an unspeakable horror.

"But even as the case brings him closer than ever to the nature of true evil, a reluctant Luther must also face the ghosts of his own past. Striding back into the line of fire, he must choose who to protect… and who to sacrifice. Whatever his next move, it will have devastating consequences for those around him - and will change John Luther forever."

There's plenty of additions, both old and new, that will be joining Elba for the new episodes. Dermot Crowley, Michael Smiley, and Patrick Malahide will be returning for the four-part series as DSU Martin Schenk, Benny Silver, and George Cornelius respectively. Wunmi Mosaku (Damilola, Our Loved Boy) will be new recruit D.S. Catherine Halliday. Regarding the new episodes, show creator Neil Cross said: "We missed John Luther. We missed some old friends. And we wanted to make the biggest, scariest, darkest, most thrilling series of Luther there’s ever been. So that’s what we’ve come back to do.” Bring it on.
