| Carmichael and her team continue to interview Hastings. They question him about the £50,000 in banknotes they found in his hotel room. Gill Biggeloe, who sits in on the interview, identifies errors in the police search procedure of Hastings's hotel room. This leads Carmichael's team to interrogate Hastings's communications data for further evidence. Meanwhile, Fleming and Arnott revisit Corbett's widow and DSU Powell. They discover that Biggeloe was involved in selecting Corbett for Operation Pear Tree, and specifically identified Hastings as someone to pursue. Fleming and Arnott present their findings to Hastings. Biggeloe was recruited by the OCG while she was working as a defence solicitor. She texts the OCG for her escape but to no avail. One of Carmichael's team, PS Tina Tranter, attempts to stab Biggeloe but is shot by Arnott. The epilogue reveals that Operation Pear Tree is now officially closed. Fleming received a commendation for her investigation into Pear Tree. Arnott was commended alongside her after an independent panel cleared him in shooting Tranter.

Biggeloe received immunity and a new identity. Hastings received a final written warning, but continues to lead AC-12. Moffatt, standing trial, claims that the £50,000 found in Hastings's hotel room is only half of the sum that was handed to him. The remaining £50,000 is never found, but Hastings is seen approaching Corbett's widow with an envelope. |||||||

## Reception

Despite less positive reviews than the previous series, series 5 was still ranked highly among critics. Review aggregator website Rotten Tomatoes holds an approval rating for series 5 at 90%, with an average rating of 8.40/10, based on 29 reviews. The website's critics consensus reads: “Line of Duty's sterling ensemble all maintain a stiff upper lip, but audiences' limbs will be quavering throughout this tense fifth season that dives deep into moral murk.” On the review aggregator website Metacritic, the series has a score of 88 out of 100 based on 5 critics.

Radio Times drama editor Eleanor Bley Griffiths wrote: "With epic interrogation scenes, surprise betrayals, grisly murders, untold secrets, massive twists... " Pat Stacey of The Irish Independent wrote: "Episode by episode, the plot is thickening, like soup that's been left sitting on a hot stove for too long." Rachel Cooke of the New Statesman was less complimentary in her review, suggesting that Mercurio struggled to give the audience a logical resolution – leading her to call series five “Jed Mercurio’s ropiest bit of work ever sent our way.” Brian Donaldson of The List had solid praise for the actors, but felt the series's plot was somewhat vague; he was critical of the script, stating: “The writing leaves many of them discussing the gravest of matters as though they're reading the contents on the back of a shampoo sachet.”
