A publicity shot from the hit BBC drama's third series appears to reveal that Wilson's glamorous killer will reappear in the new episodes.
Alice killed her parents in the first series of Luther and crossed paths with Idris Elba's title character, though the maverick cop was unable to prove her guilt.
Their twisted relationship appeared to come to an end in series two, when Luther broke his psychopathic ally out of a mental institute but refused to flee the country alongside her.
A video announcing the start of filming on the third, four-part series of Luther previously hinted at the character's return, claiming that "only Alice knows" if she will reappear in Luther's life.

Luther creator Neil Cross previously revealed that he is planning an Alice spinoff, claiming that the BBC is "very interested" in a miniseries featuring the character.
A Luther movie is also thought to be in the planning stages and would be shot after the third series has aired.
