Line of Duty Season 4
Overview
AC-12 has taken down bent coppers before, but never one this senior, this smart, or this willing to bleed for the story she's telling. Thandiwe Newton arrives as DCI Roz Huntley, a detective under pressure to catch a killer the press calls the Balaclava Man — and suspected of charging the wrong man to close the case. When AC-12 starts circling her, Huntley doesn't panic. She counterattacks, picking apart the investigators' own conduct with the same cold focus she brings to a crime scene, and Newton makes her terrifying precisely because she's never less than plausible. Underneath it all sits a real injury, literally festering, that becomes the season's grim visual shorthand for everything she's hiding. Meanwhile Ted Hastings (Adrian Dunbar) is leaned on from above to bury the inquiry, and Steve Arnott's season takes a turn that had viewers shouting at their televisions mid-episode. The interview scenes this year are the show's best: two professionals dismantling each other's timelines across a table, tapes running, nobody bluffing. If the previous season proved Line of Duty could do spectacle, this one proves it can do tragedy — nearly everyone in it is right about something, and it saves no one.
