Idris Elba has returned to the role of DCI John Luther for a fifth series of the always-gripping BBC police procedural Luther.

Set to air soon, further great news is that this series will number four episodes. The last one’s mere two really was kind of taking the you-know-what out of the term “series”.

Anyway, we now have a taste of it via the trailer just below, and fans of the series will likely be pleased about a certain face who briefly pops up. A hint to whom we’re referring to might just be the soundtrack song, a cover of Britney’s Toxic (performed by 2WEI, who are no relation to PWEI.)
