In the third season premiere of “Luther” (8 p.m., BBC America), Idris Elba returns as homicide detective John Luther, whose genius is matched by his out-of-control temper.
This time around, Luther is investigating a pair of cases. In one, a twisted fetishist is murdering women in a horrific echo of an unsolved case from the 1980s. In the other, he investigates the murder of a man who tormented others on the Internet.
At the same time, he’s being investigated for abusing suspects — an investigation that could end his career.
Elba is great. Again. So is “Luther.” Again.
The four episodes air tonight, Wednesday, Thursday and Friday.
