DSI Marcus Thurwell (James Nesbitt) is reportedly Ladbrokes favourite to be unveiled as the antagonist with odds of just 7/4, with viewers convinced that the bent copper is still alive despite being declared 'dead' by Spanish officers in the last episode.
Meanwhile, DCI Patricia Carmichael (Anna Maxwell Martin) has odds of being the villain of 2/1 according to Betfred.
Caught at last? By the look of determination on their faces, Kate and Steve look set to finally put an end to the mystery that has eluded them for months - but viewers will have to wait and see whether they do have 'H' in their sights
People across Britain are gearing up for the BBC's Line of Duty series finale tonight, with 12million viewers expected to tune in.
The show sees the officers of police anti-corruption unit AC-12 pitted against the mysterious antagonist known only as 'H' or 'the fourth man', who heads up an organised crime syndicate controlling events from the shadows and potentially from within AC-12 itself.
The series has gone from strength to strength since its release, growing from an initial audience of four million adults to more than 11million tuning in for the current series' penultimate episode.
Earlier this week, the BBC released a teaser trailer promising an action-packed finale complete with a police standoff, the return of balaclava men and the discovery of a written note with THAT 'definately' misspelling.
Line Of Duty stars Vicky McClure and Martin Compston have shared moving tributes to the show's die-hard fans as they count down the hours until the long-awaited series six finale.
The actress, who has played DI Kate Fleming since the show's inception in 2012, continued to fuel fans' concerns that the series could be coming to an end in a lengthy Twitter post, which ended with the phrase: 'Let's wrap this up!'
Meanwhile Martin, known to many as DI Steve Arnott, described working on the series as 'the job of a lifetime' and vowed that fans will finally get answers after months of theorising over the identity of the elusive 'H.'
