She’s a contemporary knight errant, upholding a code of decency against the terrors of modern life.
“Happy Valley,” whose final season premieres on Monday (streaming on Acorn TV and AMC+, broadcast on BBC America), is a pocket-size, prosaic saga — a hero’s tale contained in three six-episode seasons and embedded in a family drama.
Like all mythical heroes, Cawood has an antagonist, the psychopathic rapist and killer Tommy Lee Royce (James Norton), who is the father of her grandson.
In its structure, “Happy Valley” is very much a traditional British crime series, with seemingly unconnected plot strands and investigations that wind themselves together against a backdrop of cop-shop politics.
In the new season’s major subplot, a less-than-sympathetic female character is caught between two seemingly more capable men whose weaknesses run deeper than hers.
