Has your breathing returned to normal again yet? No, nor has ours.
Nor have we managed to absorb everything from that heart-in-mouth series finale.
But one thing is for sure – we are already hungry for more, more, MORE.
Traditionally, Line of Duty fans have had to wait a while for each new series – televisual masterpieces aren’t built in a day, after all.
Thankfully, this time around, the drama’s peerless writer Jed Mercurio has thrown us a couple of morsels that offer a taste of what we can expect from series five.
And it seems we will get to see a bit more beyond the work of the AC-12 team.
The show’s chief scribe told BBC Online: “I want to look at the personal lives of all the regulars in series five.
“They’ve taken a backseat in this series to Roz Huntley, so it would be good to explore that side of things a bit more.
“The regulars are definitely up for doing more…”
Yes, before this fourth series – and the show’s move to BBC One – viewers were privy to more private stuff about the people behind the police work.
We know, for example, that Kate is a mum, but her ex-husband has custody of their son – her family life fell apart in series two.
And in series three, viewers saw Steve grow dangerously close to suspect – and fallen cop – Lindsay Denton, while he was engaged to another policewoman.
Meanwhile, married Hastings is not above straying, as we saw in series three when his long-standing relationship with his wife was apparently in tatters.
We can’t wait to see where Mercurio will take them – and us.
Unlikely as it seems now, given the phenomenal success of the show, series five could be the end of the, er, Line – a sixth run has not yet been ordered.
“Yes. We haven’t yet had that meeting with the BBC,” Mercurio, who also penned acclaimed BBC medical drama Bodies, told Radio Times. “But if there’s not another commission, I would have to approach series five as the last.”
Keep everything crossed that it doesn’t come to this, people!
