Superintendent Ted Hastings (Aidan Dunbar) ruled at the end of season four of Line of Duty, ACC Derek Hilton (Paul Higgins) was the criminal adversary AC-12 had been playing goose chase with since the BBC series began in 2012.
With season five bringing more twists and turns to the plot than ever before, AC-12 have been focusing on bringing down the balaclava group, believing H was no longer going to be a problem.
However, in last week’s episode, DS Steve Arnott (Martin Compston) and DS Kate Fleming (Vicky McClure) made the unsettling discovery H was still active as he was leading the criminal activity of the masked group.
As the plot thickens and Hastings becoming more suspicious, it seems the superintendent could be killed off this season as the team’s trial possibly leads them to expose their boss as the corrupt police officer.
After the second episode of the fifth season, bookmakers Paddy Power have taken a flurry of bets from fans of the hit BBC drama, placing Hastings as corrupt officer H at 2/1 on their latest odds table.
However, not only is he one of the hot favourites to be revealed as the super villain terrorising the AC-12 team, but Hastings’ death has become the most likely amongst Line of Duty fans as the season reaches a peak.
With the likes of DS Arnott and DS Fleming in the running to be killed off, Hastings leads the way at 10/11 in Paddy Power’s odds to meet a grime demise.
Speaking about the influx of bets for the major character, a spokesperson for the bookmakers said: “Mother of God! Could Ted Hastings actually be a bent copper? Our odds certainly suggest it’s a possibility – with money troubles and the ominous Kettlebell investment looming over his head.
“And if that wasn’t upsetting enough news for Line of Duty fans, he’s rated the most likely major character to be killed first, though Steve Arnott isn’t far behind him as he appears to agree a deal with the devil in the form of John Corbett.”
During last weekend’s tense second instalment of the BBC crime drama, criminal adversary John Corbett (Stephen Graham), who is also the leader of the balaclava group, met with DS Arnott to discuss his work with the masked vigilantes.
In a opening episode twist, it was revealed John was working as an undercover police officer within the ranks of the balaclava group, but had lost contact with the force as he believed they were being too safe in trying to discover H’s identity.
However, bookmaker’s Paddy Power have seen an influx of bets for the undercover cop to be revealed as the super villain, with Corbett’s odds ofbeing unmasked at H at 1/5.
If this theory does ring true and Corbett is masterminding the whole greater criminal empire, could he be trying to knock DS Arnott off the block to ensure his secret remains confidential?
DS Arnott’s odds at being killed of this season, after a number of failed attempts in the past, stand at 2/1 in the bookmaker’s latest odds alongside DS Fleming’s chances of facing the chop at 3/1.
Actor Martin Compston, 34, revealed before the current season began, he isn’t sure of his character’s fate in the latter seasons of the BBC drama.
With the filming having already come to a wrap and a sixth season commissioned, Martin spoke about his future on Line of Duty during an interview on This Morning with hosts Philip Schofield, 57, and Holly Willoughby, 38.
Speaking of the future of the series, Philip and Holly went on to discuss the sixth season, to which Martin added: “I don’t know whether I’ll be in it though.
“You don’t know who’s going to make it to six, do you?” the Line of Duty star teased, with Philip and Holly taken-aback by the news.
Of his time on the show, Martin continued: “That’s the thing with the show. It’s been the job of a lifetime in terms of the script and quality.
“I’ve never laughed so much on any other set in my life. We do love it. It’s been a great nearly seven, eight years now.
“If Jed decided it was your time to go, you just need to say thank you for the memories and accept it.”
Line of Duty continues Sunday at 9pm on BBC One.
