It's the big question the nation wants answered: No, not how Boris Johnson really refurbished his flat (that's second on the list of big questions), but who is "H", or "the fourth man/woman", as H is now known.
On Sunday evening, a large proportion of the nation will be glued to their TV sets, hoping to have the H question and many more loose ends tied up in the final episode of the latest series of Line Of Duty.
In the era of binge-watch TV, heightened during the pandemic, the twists and turns of AC-12's long-running hunt for bent coppers have brought the country together like nothing else. For the last six weeks, fans have dissected and analysed each scene, every little look, in forensic detail, and - Jesus, Mary and Joseph and the wee donkey - found themselves unable to go more than a few hours without quoting their hero, Superintendent Ted Hastings.
Last week's penultimate episode earned an average of 11 million viewers and 51.7% of the night's audience share, the BBC said, making it the most-watched ever episode of the show, which launched in 2012 and has now played out over six series. To put this into context, viewing figures for the Oscars on the same night in the US were just 9.85 million, in a country with a population of 328.2 million, compared with our 66.7 million.
This season's Line Of Duty finale, basically, is the World Cup final of TV drama.
