Our brooding detective John Luther (Idris Elba) is back for a nightmarish new case that sees a killer wreaking havoc across London, committing brutal murders.
Luther will be under pressure from his superiors to find the culprit in series 5 of the BBC One crime drama, but will also find strings being pulled by London gangsters.
As if this and a new sidekick weren’t enough to get excited about, Luther must also deal with the return of his very own killer/love/friend Alice Morgan (Ruth Wilson), who seemed to be killed off-screen last series.
Will Luther and we get the answers we need?
Here are all the new and returning faces for the new batch of episodes this winter.
