It is a series of strong drama and criminal events that we are experiencing during the second season, when Katharine brings the Croatian Elinka to the house for questioning because she is one of several women who have been rescued from traffickers. The solution seems to be to put her with her old Polish friend Winnie before she joins the investigation from house to house of the gunman who killed three female victims. Shortly after his wife's death, Nefison Shawn returns but Catherine still suspects that there is a danger in the young man chasing the prostitutes.
The British import spreads its wings in its second go round, following the tight case that propelled Season 1 into one of the greatest surprises... and it's as great as ever.
Revisiting the series and overcoming the early obstacles was, indeed, rewarding. Not every plot twist is original or even believable, but the second season only solidifies how impressive the whole Happy Valley world is.
Above all else, it's Lancashire's performance that makes Happy Valley tick. At various stages of the series she is left bruised and hysterical, and you feel every single emotion along with her.
Wainwright layers her stories like a tightly structured, best-selling thriller, so as well as the hunt for the murderer, now identified as a serial killer, other interlinked secondary plots are introduced.
