DCI John Luther is still on the case!

BBC America has ordered Season 5 of the crime drama "Luther," starring Idris Elba as the titular hard-boiled detective.

The four-part season will begin filming early next year. Season 4 aired as a two-hour movie in December 2015 and followed Luther as he was drawn from isolation back to London to help track down a cannibalistic serial killer.

"What happened to John Luther after we last saw him striding unbowed through the streets of his city, his blood red London? It can't be over, can it? There's so much we don't know. So much unfinished business," said creator Neil Cross.

"In the end, we picked up the phone to some old friends and asked if they'd like to find out what happens next. It turns out, they would. So that's what we're going to do. We're going to find out what happens next. Now what? Luther's coming back. That's what."

Elba quipped, "I look forward to putting the coat back on."
