Line Of Duty has been renewed for a further two series, the BBC has confirmed.
Those ratings got even bigger over the past few weeks with more than 7 million watching the series finale last weekend.
So it's no surprise that the BBC has revealed a further two series have been commissioned.
BBC's Director-General Tony Hall revealed this week: “I am very excited to say there’s not one but two more series of Line of Duty. So hooray for AC-12!”
However we may have a while to wait yet before any new episodes make it to TV.
Show creator Jed Mercurio previously sai that Series 5 of Line Of Duty may not air until 2019.
“The plan is we won’t shoot Line of Duty series five until next year and that means it won’t be on air until 2019," he revealed before Sunday's series finale. "I am not planning to write it until next year because I am working on [something else]."
Jed told the Daily Mirror newspaper: “We haven’t even decided if the next antagonist will be male or female, we are that far off from puzzling it out.
“I have got various ideas but what is crucial is whether we are approaching series five as being the last series, and that depends if we can persuade the BBC to commission a series six.”
The BBC previously confirmed the show's fifth series after moving the show to BBC One for Series 4.
Charlotte Moore, BBC Controller of TV Channels and iPlayer, said at the time: "Line of Duty is original, bold, gripping drama that gets the nation talking and the time is right to bring the series to an even broader audience on BBC One.
"Jed Mecurio's explosive thriller will find a new home on BBC One for two more series and create room for new drama to flourish on BBC Two. Thanks to Jed, Simon Heath's World Productions, and Stephen Wright at the BBC for producing the record-breaking show."
