Chris Chibnall's ITV whodunnit drama has kept the nation on the edge of their seats for two years now, but there's unfinished business on the south coast that needs to be resolved.
As the credits rolled at the end of the series two finale, ITV announced that there would be a third series of the hit drama that pulled in nine million viewers on Monday nights to the network - and that series three will be the final part of a trilogy.

What is the plot of Broadchurch series 3, do you have any spoilers?
The plot of the series is as ever one of the closest guarded secrets at ITV.
The new series will deliver a brand new case for Miller and Hardy with the detectives teaming up once again, this time to investigate a serious sexual assault and its consequences as the drama's Dorset community comes under scrutiny. Based on a year of research, the drama's last series will look at the emotional cost to everyone involved and the irreparable damage to friendships and relationships.
"This is the final chapter of Broadchurch," said writer Chris Chibnall who will take over as showrunner on Doctor Who in 2017. "We have one last story to tell, featuring both familiar faces and new characters. I hope it's a compelling and emotional farewell to a world and show that means so much to me."
That's pretty much all we know for now (if you really want to dig around the internet you can find some filming shots that you could see as spoilers) - but as with any whodunnit drama, probably the less you know the better before it airs.
