Red Hair. Blue lights. Manchester rain. Honestly, if you weren't watching ITV in the mid-2010s, you might have missed how Scott and Bailey Season 4 fundamentally shifted the DNA of the "buddy cop" genre. It wasn't just another year of chasing "bad guys." It was the year everything got messy.
Rachel Scott and Janet Bailey were always a study in contrasts. One is a chaotic, intuitive mess; the other is a steady, procedural powerhouse. But by the time the fourth series rolled around in late 2014, the show stopped being about the crimes and started being about the toll. It’s heavy. It’s brilliant. And if we’re being real, it’s probably the most authentic portrayal of the Major Incident Team (MIT) ever put to film.
Suranne Jones and Lesley Sharp didn't just play cops. They played exhausted women. That’s the distinction.
The Promotion That Broke the Status Quo
The biggest hook of Scott and Bailey Season 4 wasn't a serial killer. It was an exam. Specifically, the Sergeant's exam.
Remember the tension in the office? It was palpable. Both Rachel and Janet were up for the same promotion. This wasn't some manufactured TV drama where they high-five and say "may the best woman win." It was awkward. It was competitive in that quiet, British way that makes your skin crawl. When Rachel Scott actually gets the promotion over Janet, the power dynamic of the entire show flips on its head.
Suddenly, the protégé is the boss.
Imagine having to tell your best friend—the person who mentored you—that their paperwork isn't up to snuff. Rachel, now a Sergeant, has to manage Janet. It’s clumsy. Janet, ever the professional, tries to take it on the chin, but you can see the cracks. The writers, including the legendary Sally Wainwright and Amelia Bullmore (who also plays the formidable Gill Murray), understood that workplace resentment is often more compelling than a DNA match.

Case Studies in Grit: The Crimes of Series 4
While the internal politics simmered, the cases remained brutal. We kicked off with the disappearance of Robin McKendrick. It seemed like a standard "missing person" fluke, but it spiraled.
One of the standout elements of this season was the introduction of DS Rob Waddington, played by Danny Webb. He brought a different energy to the MIT. It wasn't just the "Gill Murray Show" anymore, though Amelia Bullmore’s portrayal of Gill remained the backbone of the series. Gill’s looming retirement throughout the season added this ticking clock element. You felt like the era was ending.
Then there was the "Redhead" case. This was peak Scott and Bailey. It showcased the meticulous, often boring, but ultimately rewarding nature of real police work. No "enhance" buttons on grainy CCTV. Just hours of interviews and cross-referencing.
The show has always leaned on the expertise of Diane Taylor, a former DI with Greater Manchester Police. That’s why the dialogue feels so sharp. When they talk about "the job," they aren't using Hollywood shorthand. They’re using the language of people who have sat in interview rooms for eighteen hours straight.
The Domestic Collapse
You can't talk about Scott and Bailey Season 4 without talking about the home lives. Or the lack thereof.
Janet’s house is a battlefield. Her daughter, Taisie, is growing up and acting out. There’s a specific scene involving a shoplifting incident that just feels so real. Janet is this high-level detective who can track down killers, but she can't get her own kid to talk to her. It’s a classic trope, sure, but played with such understated grief by Lesley Sharp that it avoids the cliché.

Rachel, meanwhile, is... well, Rachel. She’s living in a hotel for a chunk of the season. She’s trying to be a "grown-up" Sergeant while her personal life is essentially a pile of discarded takeaway containers. Her relationship with her sister, Dorothy, continues to be the only thing anchoring her, yet even that is fraught with the baggage of their shared childhood.
Why the "Vulnerable" Cop Worked
We’ve seen the "tortured male detective" a thousand times. He drinks whiskey and stares at a rainy window. Boring.
Scott and Bailey Season 4 gave us something else: the "functioning" female detective who is just barely holding it together. They don't have time to stare out of windows. They have to pick up the kids. They have to manage the junior officers. They have to deal with the casual sexism of the force while pretending it doesn't bother them.
The brilliance of this season lies in the quiet moments. It’s the conversations in the car. It’s the shared cigarettes (back when they still did that) and the unspoken understanding that the job is destroying them, but they wouldn't do anything else.
Gill Murray’s Final Stand
Let’s be honest: Gill Murray is the best character on the show.
In Season 4, Gill is staring down the barrel of retirement. She’s being pushed out by a system that values "new blood" over decades of institutional knowledge. Her struggle with alcohol—specifically her reliance on it to numb the stress of the job—becomes a focal point.

The "Shadow Puppet" storyline was a masterclass in tension. When Gill is targeted, it’s not just a plot device to get the audience excited. It’s a commentary on the vulnerability of these women. They spend their lives protecting others, but who protects them? The finale of Season 4 is a harrowing, claustrophobic piece of television that ranks among the best the UK has ever produced.
It wasn't a "happily ever after." It was a "we survived this day."
Reality vs. Fiction: The GMP Influence
The show’s commitment to realism is its greatest asset. In Scott and Bailey Season 4, the procedural aspects were tightened even further.
- The SIO Role: Seeing Rachel step into the Senior Investigating Officer role showed the bureaucratic nightmare of the job.
- The Interview Room: The scenes in the "glass box" are legendary. The psychological warfare used to get a confession isn't about shouting; it's about finding the one thread of a lie and pulling it until the whole story unravels.
- The Geography: Manchester isn't just a backdrop; it’s a character. The grim industrial landscapes and the gentrifying city center perfectly mirror the friction between the old-school policing and the new corporate requirements of the force.
How to Revisit the Season
If you're planning a rewatch, or if you're coming to it for the first time, don't rush it. This isn't a show meant for "second-screen" viewing. You’ll miss the flickers of emotion on Lesley Sharp’s face. You’ll miss the sharp, biting wit of the script.
- Watch the body language. Notice how Rachel’s posture changes once she gets the Sergeant stripes. She tries to take up more space. It’s subtle and brilliant.
- Listen to the silence. The show uses a lack of score during intense moments to ground the drama in reality.
- Track Gill’s journey. Her arc in Season 4 is perhaps the most tragic and well-realized "end of career" story in TV history.
Scott and Bailey Season 4 proved that you don't need explosive car chases to have high-stakes television. You just need two women in a car, a difficult case, and the crushing weight of reality.
Next Steps for Fans
To truly appreciate the depth of the series, watch the special "behind the scenes" features regarding the consulting work done by the Greater Manchester Police. It’s eye-opening to see which parts of the "Redhead" case were lifted directly from real-world investigative techniques. After finishing the season, compare the promotion arc here to the later developments in Series 5 to see how the power shift permanently altered the duo's friendship. If you are looking for similar gritty realism, seek out Sally Wainwright’s other masterpiece, Happy Valley, which shares much of the same DNA regarding the toll of police work on the human psyche.
