As Sunday’s conclusive episode threatens to tie up the “H” storyline, blowing the whole house of cards asunder, there is a further, irresistible twist to Line of Duty’s playful cat and mouse chase of trust in the Establishment. Who really wins in the search for decency? What small details we are let in on the lives of Hastings, Arnott and Fleming suggests anyone but them. As it stands after episode six, Hastings is a harassed divorcé with a history of money problems, facing enforced retirement under the unscrupulous meddling of his professional Grim Reaper, Patricia Carmichael. Arnott is impotent, addicted to painkillers and still working his way through a rotating wardrobe of snooker player’s waistcoats. Poor old Kate Fleming has one friend (Arnott), a child she barely sees and the very occasional half lager by way of comfort for it all.
The cloud of doom hanging over the good folk of Anti-Corruption Unit AC-12 never comes as a surprise. It isn’t meant to. Line of Duty’s special skill is in recalibrating the biblical morality tales between good and bad, virtue and vice. It is about testing the boundaries of our ethics, asking difficult questions in difficult times.
The cross-generational drama is the inverse of all those superhero stories that rotate around the one basic premise that if only superhuman powers existed, we might save the world. Hastings, Arnott and Fleming are notably flesh and blood. They are drawn together by stoic principles and their shared understanding of the futility in trying to upend the status quo. Our three heroes will roll their sleeves up, have a go, achieve what they can against staggering odds and thankless institutional disadvantage, then return home each night, once again to their empty rooms.
The one flicker of romance in Line of Duty? Its sole redemptive clause is that all three beautiful faces of AC-12 are doing more than most of us could dream of, given the circumstances.
