The third and final season of "Luther" debuts -- and ends -- this week on BBC America.
There are only four episodes of "Luther" in this last installment, and the episodes will air at 10 p.m. on BBC America, Tuesday through Friday. (Correction: Wednesday night's episode will air at 9 to accommodate the 10 p.m. airing of "Broadchurch.")
"Luther" stars Idris Elba as a troubled (understatement of the century!) London detective assigned to investigate some of the foulest crimes in the city. Elba won a Golden Globe for his acting on the show in 2012.
"Luther" is dark, but superb. If you're interested in catching up (seasons are short: Season 1 had six episodes and Season 2 had four) the earlier seasons are streaming on Amazon Prime and Netflix.
