BBC's original show Happy Valley is back for its third and final series after an explosive two seasons.
The Bafta-winning series stars Sarah Lancashire as Sergeant Catherine Cawood. When Catherine discovers the remains of a gangland murder victim in a drained reservoir, it sparks a chain of events that leads her straight back to Tommy Lee Royce, the rapist of her late daughter, and father of her grandson, Ryan.
Ryan is now sixteen, and has his own ideas about the kind of relationship he wants to have with his biological father.
