“The BBC will be desperate for Mercurio to come back with a seventh series but this felt like the right place to end it. I’ve griped about various bits of this show over the years but it stands head and shoulders above most other dramas. It has kept us guessing and kept us talking. And it’s clever. To tie up a story this complex, leaving no loose ends, is a superb achievement.” “After all the shenanigans and conspiracy, in the end a surprising amount rested on trusting the audience would assume nobody with a Brummie accent could be a master criminal. It worked on me! Whatever Line of Duty’s limitations, few programmes come close to it as a demonstration of pure plotting. It has proved that there is still an appetite for weekly, cliffhanger-laden, jargon-filled chaos, but that’s enough. Let that be an end of it.”
