After three extremely tense episodes, the fourth and final instalment of BBC One’s Northern Ireland-set crime drama Bloodlands aired on BBC One tonight.
Chris Brandon’s series, which is executive produced by Line of Duty’s Jed Mercurio, follows DCI Tom Brannick (James Nesbitt) as he searches for Belfast-based serial killer Goliath – and there have been twists and turns aplenty in the build-up to the show’s climax.
The second episode ended with a huge bombshell which saw the show slightly change tack for its third episode, and that looks set to continue in the grand finale.
