Line of Duty fans are gutted that the series has now come to an end - with one heck of a series finale.
The BBC's highly popular drama has had us gripped to the edge of our seats since 2012, as we've tried to understand the various plot twists - not to mention all of the acronyms and who on earth 'H' is. And after six series, we really hope this isn't the end of Line of Duty forever.
We know you'll be looking for another crime drama to sink your teeth into and help you fill the void, so we've pulled together a list of the best crime dramas out there to help you fill the void.
This three-part documentary series investigates the real dirty police in London's Met, which inspired the storyline of Line of Duty.
