David Tennant is back as DS Alec Hardy, and Olivia Colman reprises her role as local detective Ellie Miller whose husband was revealed as the child-killer at the end of last series.
Has Ellie managed to put her life back together? Why is Alec still in town? And what about the dead boy's family – Andrew Buchan as Mark Latimer, and Jodie Whittaker as Beth Latimer, will both return to their roles too.
With the likes of Eve Myles, Marianne Jean-Baptiste, Charlotte Rampling, and James D'Arcy joining the cast, it's set to be another stellar series.
