Your eyes are not deceiving you: That's Ruth Wilson as Alice Morgan in the final frame of the trailer, the psychopathic foil to Luther who allegedly died in season four. We've known for a while that Alice would return this year, but seeing her in the closing moments is still a great surprise.As for the rest of the trailer, well, there's a lot to unpack here. Set to a haunting cover of Britney Spears' "Toxic," the trailer shows us DCI John Luther, who is back on the scene, investigating the crimes of what looks to be a budding serial killer. Luther isÂ joined by his new partnerÂ DS Catherine Halliday (Wunmi Mosaku), and, according to the official synopsis, the two are "confounded by a complex tangle of leads and misdirection that seems designed to protect an untouchable corruption." That sounds a lot like the work of one Alice Morgan, whose genius-level I.Q. allowed her to get away with the murder of her parents in season one. Is she luring Luther into a new trap, or will she help him decode a new master's web? That appears to be the big question going into season five.Luther will return to BBC One next month for a four-episode season, which is expected to air on BBC America sometime in 2019. As for the show's future, Elba recently told Empire,Â â€œThis season is not the end. But there are some real changes that will happen." We can't wait to see what's in store for us.
