Popular crime drama Happy Valley is back almost seven years since the last series was screened for the third and final series. Starring Sarah Lancashire, the drama follows police sergeant Catherine Cawood and her complicated and tragic family life.
The third series promises to bring all the drama and characters that viewers know and love but almost seven years since series two was aired, it can be easy to forget the plot of the previous episodes. From arrests, mystery killings and romance there is plenty to catch up on.
