Line Of Duty: Is Patricia Carmichael 'H'?
We can kind of see this to be honest
With each week that goes by,
Line Of Duty fans hope to be one step closer to unveiling who 'H' - or 'The Fourth Man' - is.
Last night's episode saw Jo Davidson's "partial DNA match" revealed as Tommy Hunter as well as a tense stand off between Ryan Pilkington and Kate Fleming, as AC-12 continue their search for Gail Vella's murderer (and bent coppers).
What it also saw is social media explode with theories about who 'H' is - the notorious senior police officer who is heavily embedded in organised crime. While some clues have pointed to Ted Hastings and others to Kate, a new theory suggests Patricia Carmichael could actually be who we're looking for.
