Sally Wainwright didn't just write a police procedural. Honestly, she wrote a haunting. When Happy Valley series 2 first hit screens, the pressure was immense because the first season was such a lightning-in-a-bottle moment for British TV. Most shows stumble here. They go too big, too Hollywood, or they lose the thread of what made the characters feel like people you’d actually meet at a bus stop in Yorkshire. But series 2? It’s arguably better. It is denser. It is darker. It’s a masterclass in how to juggle four different subplots without dropping the emotional weight of a single one.
You’ve got Sarah Lancashire as Catherine Cawood, a woman who looks like she carries the weight of the entire Calder Valley on her shoulders. She’s tired. You can see it in how she zips up her high-vis jacket. This season kicks off eighteen months after the horrific events of the first, and Catherine is somehow still standing, though the ghosts of Tommy Lee Royce are never more than a few feet behind her.
The Nightmare of Tommy Lee Royce and the Series 2 Shift
Basically, the brilliance of Happy Valley series 2 lies in how it handles its villain. James Norton’s Tommy Lee Royce is behind bars, yet he feels more dangerous than ever. He isn’t just a physical threat anymore; he’s a psychological parasite. He’s found a way to reach out from his cell through Frances Drummond, played with a terrifying, quiet desperation by Shirley Henderson.
This isn't your typical "evil mastermind" trope. It’s pathetic and real. Frances is a "prison groupie," a very real phenomenon where isolated individuals fall in love with high-profile inmates. Her presence in the lives of Catherine’s grandson, Ryan, creates a slow-burn tension that makes your skin crawl. You want to scream at the television. It’s a weirdly intimate kind of horror.
The season also introduces a sprawling serial killer investigation. Catherine discovers a body in a garage, which turns out to be Tommy Lee Royce’s mother. Talk about a complication. Suddenly, the woman who hates Tommy most in the world is the lead suspect in his mother's murder case. It’s messy. It’s complicated. It’s exactly how real life works, where nothing is ever cleanly resolved just because someone is in handcuffs.

While the hunt for the "prostitute killer" is the engine that drives the police work, the real meat of the season is the disintegration of Detective Sergeant John Wadsworth. Kevin Doyle—who most people recognize as the lovable Molesley from Downton Abbey—plays a man who is the polar opposite of lovable here. He’s a weak, cheating, panicked mess.
His story is a cautionary tale of how one bad decision can turn into a literal corpse. After his mistress, Vicky Fleming, blackmails him, John kills her in a moment of blind rage. The irony? He ends up being part of the team investigating his own crime. Watching him try to frame the serial killer for his own murder is some of the most stressful television ever produced. It’s uncomfortable to watch. It’s supposed to be.
Why Happy Valley Series 2 Feels So Authentic
People talk about "gritty" dramas all the time, but usually, that just means "it's raining and everyone is wearing grey." In Happy Valley series 2, the grit comes from the dialogue. Sally Wainwright has this uncanny ability to make police briefings sound like actual conversations people have in an office. They talk about tea. They talk about their kids. They make inappropriate jokes because that’s how people in high-stress jobs cope.
The show captures the specific landscape of West Yorkshire in a way that makes the setting a character. The hills are beautiful but isolating. The wind looks cold. When Catherine is walking her dog or dealing with her sister Clare’s (Siobhan Finneran) relapse into alcoholism, you feel the dampness of the air. It’s a specific kind of British misery that is somehow deeply comforting to watch because it feels honest.

- The Acting: Sarah Lancashire’s performance is a powerhouse. She doesn’t "act" like a cop; she exists as one. The way she handles a suspect is completely different from how she handles her sister.
- The Stakes: They aren't global. No one is saving the world. They are saving a child’s mind, or a family's reputation, or just trying to get through the shift without losing their job.
- The Morality: There are no "perfect" heroes. Even Catherine is flawed—she’s stubborn, she’s judgmental, and she can be incredibly cruel to the people she loves most.
The Problem of Ryan and the Bloodline
A huge chunk of the narrative tension in this second outing is centered on Ryan. He’s getting older. He’s asking questions about his dad. The fear that Tommy Lee Royce’s "evil" is hereditary hangs over Catherine like a guillotine. It’s a heartbreaking exploration of nature versus nurture.
When Ryan starts receiving gifts and letters, the audience feels Catherine’s panic. You see her struggle between being a loving grandmother and a traumatized victim of the boy's father. It’s a nuanced take on trauma that most shows would simplify into a "good vs. evil" battle. Here, it’s just a grandmother trying to protect a little boy from a truth he isn't ready for.
Deconstructing the Finale’s Impact
The way Happy Valley series 2 wraps up is both explosive and quiet. John Wadsworth’s story ends on a bridge, a moment that felt inevitable from the first episode of the season. It wasn’t a "win" for the police. It was a tragedy for everyone involved.
Meanwhile, Catherine’s confrontation with the reality of Tommy’s influence over Ryan doesn't end with a big shootout. It ends with a conversation. It ends with the realization that you can’t lock out the world forever. The final shot of Catherine looking out over the valley, watching Ryan play, is a haunting reminder that while she won this round, the war is never really over.

Critics from The Guardian and The Telegraph praised the season for its "unflinching realism," and they weren't wrong. It managed to maintain a 100% rating on Rotten Tomatoes for a reason. It didn't rely on gimmicks. It relied on the fact that we care about these people.
Actionable Takeaways for the Ultimate Viewing Experience
If you’re planning a rewatch or diving in for the first time, keep these things in mind to truly appreciate the craftsmanship:
- Watch the backgrounds: Sally Wainwright loves to plant subtle details in the background of Catherine’s house that hint at her mental state and her obsession with her late daughter, Becky.
- Listen to the soundscape: The series uses silence and ambient noise (the hum of the radio, the wind on the moors) far more effectively than a heavy musical score. It grounds the drama in reality.
- Track the parallels: Notice how John Wadsworth’s domestic life mirrors Catherine’s in weird, distorted ways. Both are trying to maintain a facade of normalcy while their lives are actually in total chaos.
- Pay attention to Clare: Siobhan Finneran’s performance is the secret weapon of the series. Her struggle with sobriety is the emotional anchor that keeps Catherine from drifting away into pure cynicism.
- Context matters: Remember that this season was filmed and released during a time of significant budget cuts to British policing, which is subtly referenced in the lack of resources Catherine and her team face throughout the investigation.
The legacy of this series isn't just in the awards it won. It's in the way it changed how we look at female protagonists in crime drama. Catherine Cawood isn't a "girl boss" or a "femme fatale." She’s a grandmother with a badge and a broken heart, and that is why we’re still talking about her years later. If you want to understand the peak of British "kitchen sink" noir, this is it. Go back and watch the scene where Catherine confronts Frances in the school—it’s a masterclass in tension without a single weapon being drawn. That is the power of the writing. It stays with you. It bothers you. It makes you want to watch it all over again just to make sure you didn't miss a single flicker of emotion on Sarah Lancashire's face.
