Idris Elba is back as DCI John Luther as season five returns to the BBC.
But the real questions is what happened to Alice?
In a one-off special Alice ‘died’ off screen, but we’ve seen Ruth Wilson who plays her in the trailer.
The Psychopath/genius research scientist first met Luther when he investigated her parents murder, though he later worked out she was responsible.
Luther couldn’t prove it, however, and ended up being friends with her.
We last saw Alice in season three, then we were told she was drowned by Megan (Laura Haddock) in the first episode of season four.
It all happened supposedly off screen so it was never confirmed and there was no body. We all know what that means.
True enough Alice pops up in the trailer for season five, she’s alive!
Ruth Wilson has spoken about her return.
Ruth Wilson returns as Alice Morgan in Luther series 5.
"We find that Alice isn’t actually dead," she said talking to Digital Spy. "Things have all gone a bit wrong, so she’s come back to get Luther’s help."
Wilson also said Alice is "back with a vengeance" – and is (somehow) darker than ever.
"She’s funnier than ever; she’s more lethal than ever and she and Luther get up to some dastardly things," she said. "This season we certainly see a lot more to Alice."
And if you’re wondering if we’ll get any answers as to what happened Elba said: "I think I can say, safely, that we answer that in this season."
Where is Emma?
Rose Leslie on the other hand is nowhere to be seen. The actress played Emma, Luther’s new partner in season four.
The Game of Thrones star is not back for season five.
Instead Luther is paired up with DS Catherine Halliday played by Wunmi Mosaku.
