THE excitement ahead of Line of Duty's finale on Sunday has reached fever pitch.

But if you have missed out on the twists and turns of the six series depicting AC-12's pursuit of "bent coppers" there is still time to catch up - just!

The sixth series of the BBC One show, starring Vicky McClure, Adrian Dunbar, Martin Compston and Kelly Macdonald, will come to an end this weekend. A seventh series has not yet been announced - so fans are hopeful that many questions will be answered such as who is "H" - the corrupt officer responsible for the mass conspiracy.

If you want to get caught up ahead of the finale, settle in and grab some popcorn because Buzz Bingo has crunched the numbers to see how many hours you would need to put aside to watch all six series.

It would take 2,097 minutes or 34.9 hours to get fully caught up, that’s approximately one day and hours if you wanted to watch it non-stop.

However, if you wanted a comfort break and some sleep from BBC’s exhilarating drama to get prepared for the reveal of ‘H’ in Sunday’s finale it would take roughly two days.

Which means with the finale premiering on Sunday at 9pm, you really need to start on Thursday or Friday

A spokesperson for Buzz Bingo said, "We've all been hooked by Line of Duty over the recent weeks and we were pleasantly surprised we could power through the entire series to date in just under 35 hours.

"Plenty of time to catch for those who haven't yet seen it, ahead of the season six finale on Sunday!"

Line Of Duty secured its most-watched episode on Sunday night.

The penultimate episode of the police procedural, created by Jed Mercurio, earned an average of 11 million viewers and 51.7% of the audience share, according to the broadcaster.

Line Of Duty returned to screens in March with 9.6 million viewers, up on the last series’ finale, which earned 9.07 million.

Mercurio, whose credits also include Bodyguard and Bodies, said: “Thanks so much to everyone watching #LineofDuty6. The whole production team is thrilled and flattered by the amazing response.”

The new series has seen anti-corruption unit AC-12 take on a new case, but Detective Inspector Kate Fleming (McClure) is no longer on the squad and is working on a murder investigation with a different department, which has come under suspicion from AC-12.

Sunday’s episode saw Acting Detective Superintendent Joanne Davidson (Macdonald), boss of the suspected department, unmasked by AC-12 and secrets about her family background revealed.

The final episode on Sunday will, it is hope, see the search for “H” – – come to an end.

A trailer released on Monday offered fans a first glimpse of the series finale.

“All these suspicious deaths were orchestrated by one officer in particular – H, the fourth man,” says Superintendent Ted Hastings.

The AC-12 team are seen in a shootout before viewers are told: “Every investigation has led to this.”
