THE `Line of Duty' finale tomorrow is expected to break viewing records as fans finally find out who shadowy supervillian `H' is.
Suggestions from the stars that it might be the last ever episode of the hit BBC One drama and the broadcaster's decision not to release the entire series in one go has seen anticipation reach fever pitch.
A popular social media account yesterday released never seen before images it claimed had been taken during filming of the final episode.
Last week saw Line of Duty become the most-watched TV drama in 13 years after beating Bodyguard and Downton Abbey's viewing figures by reaching an audience of 10.9 million 51.7 per cent of the audience share.
For those yet to watch the ratings juggernaut, catching up from the first episode would take 2,097 minutes or 34.9 hours to get fully caught up - approximately one day and 12 hours - to watch it nonstop, according to Buzz Bingo.
However, the custody clock has run down on that, as it estimates if a comfort break and some sleep was included ahead of Sunday's big reveal, binge watching would have to have started no later than Friday.
As excitement mounts, a supermarket and Scottish police force are among those making the most of its popularity on social media.
Ayrshire Division of Police Scotland used a GIF of Co Fermanagh actor Adrian Dunbar as Superintendent Ted Hastings to reinforce its hashtag #KeepingPeopleSafe.
Meanwhile, supermarket Aldi, Craft & Slice beer and pizza promoters and BBC children's channel Cbeebies all used Det Supt Jo Davidson's iconic `no comment' interview as a meme to advertise themselves.
Not to be outdone, bookmaker Paddy Power released two videos pastiching the fictional AC-12's investigations into OCGs (organised crime groups) with a comedy police hunt for the head of a CTG (cowboy tipping group) starring footballer Peter Crouch among others.
