If you only know Villanelle as the woman who wears couture while stabbing people in the eye, you're missing half the story. Honestly, the Killing Eve book series is a completely different beast than the BBC show that made Sandra Oh and Jodie Comer household names. Luke Jennings, the journalist-turned-novelist behind the madness, didn't actually write a sprawling epic at first. He wrote a series of four novellas—Codename Villanelle—that were eventually bound together.
It’s weird. Most people assume the books are just a dry blueprint for the show. They aren't. They’re colder, more clinical, and arguably much more cynical.
The Killing Eve Book Series vs. The TV Glitter
Let's be real: the TV show is a fever dream of fashion and sexual tension. The books? They feel more like a classic spy thriller that got hijacked by a psychopath. In the Killing Eve book series, Eve Polastri isn't quite the chaotic, hair-flipping mess we see on screen. She’s more methodical.
Villanelle is the biggest shocker for show-only fans. In the books, her name is Oxana Vorontsova. We get her full backstory early on, and it’s bleak. There’s no "funny" Villanelle here. She’s a predator. Pure and simple. Jennings writes her with a chilling lack of empathy that makes her TV counterpart look like a stand-up comedian. She doesn't crack jokes about Shepard's pie. She just executes.
The first book, Codename Villanelle, sets the stage. We see the recruitment. We see The Twelve as a shadowy, almost bureaucratic nightmare rather than a vague plot device that changes every season. If you've ever felt frustrated by the show's refusal to explain who is actually in charge, the books are your antidote.
Why the ending of the books is so controversial
Fans of the show were famously livid about the series finale. You remember it. The bridge, the water, the total lack of closure.
Well, the Killing Eve book series ends in a way that would make TV viewers' heads spin. In the final book, Die For Me, Jennings goes places the showrunners were too scared to touch. Without spoiling every single beat, let’s just say the "will they / won't they" dynamic reaches a definitive, physical, and permanent conclusion.

Some people hate it. They think it’s too neat. Others find it cathartic because it actually gives these two women a destination.
Jennings has actually spoken out about the TV ending, too. He wasn't exactly thrilled with how the show handled his characters toward the end. He wrote an op-ed for The Guardian basically saying that his version of Villanelle would never have succumbed to the fate she met on screen. He sees her as a survivor. A winner.
Understanding Luke Jennings’ Vision
To get the Killing Eve book series, you have to understand where Luke Jennings is coming from. He’s a dance critic. That sounds irrelevant, right? Wrong. The way he describes Villanelle’s movements—the grace, the precision, the sheer physicality of her violence—is incredibly rhythmic.
He didn't want to write a "girl power" story. He wanted to write a story about obsession.
The prose is sparse. It’s not flowery. It’s almost like a police report written by someone who appreciates a good bottle of wine. You get these long, detailed descriptions of what Villanelle is eating or wearing, followed by a two-word sentence about a murder.
- Codename Villanelle (2018)
- No Tomorrow (2019)
- Die For Me (2020)
That’s the trilogy. It’s a fast read. You can probably blast through all three in a weekend if you’re committed. But be warned: the pacing is relentless.

The Twelve: More than just a name
In the TV show, The Twelve are basically the "bad guys of the week" who eventually become a confusing mess of double agents. In the Killing Eve book series, they are a high-level geopolitical entity. They have clear goals. They represent the privatization of global assassination.
Jennings uses the books to explore how easy it is for someone like Oxana to disappear into the gears of a corporate machine. She isn't a "rogue" assassin; she's an elite employee with a very specific skillset and a very expensive lifestyle to maintain.
What most people get wrong about Eve and Villanelle
There’s this misconception that the books are just "darker versions" of the show. It’s more than that. The core relationship is different.
In the show, there’s this cosmic, almost supernatural pull between them. In the Killing Eve book series, it’s a bit more grounded in tradecraft. Eve is obsessed because Villanelle represents the ultimate challenge to her intellect. Villanelle is interested because Eve is the only one who actually sees her work for what it is—art.
Also, can we talk about Niko? In the books, Eve’s husband is... well, he’s not the mustache-growing, bridge-playing guy from the show. The stakes for Eve’s personal life feel much more permanent in the text. When things break in the books, they stay broken.
Is the Killing Eve book series worth your time?
Look, if you want the high-fashion camp and the witty banter of the early Phoebe Waller-Bridge episodes, the books might feel a bit cold. They are noir. They are gritty. They don't care if you like the characters.

But if you want to see how this story was supposed to end before the TV writers' room got a hold of it, you need to read them.
The books offer a level of internal monologue that television just can't capture. You're inside Villanelle's head. You see the logic of a psychopath. It’s not "crazy" logic; it’s perfectly rational, which makes it ten times scarier.
How to approach the series today
If you’re starting now, forget the show exists for a second. Start with Codename Villanelle. Pay attention to the way Jennings describes the kills. They aren't meant to be "cool." They are meant to be professional.
The transition from the first book to the second, No Tomorrow, is where the hunt really intensifies. This is where the global scale of the conspiracy starts to leak into Eve’s mundane life. It’s uncomfortable. It’s supposed to be.
Actionable Steps for the Dedicated Fan
If you've finished the show and feel like there's a hole in your life, the Killing Eve book series is the only way to fill it. Here is how to get the most out of the experience:
- Read the novellas in order. Don't jump to the third book just to see the ending. The slow build of Eve’s obsession is the best part of the writing.
- Compare the backstories. Read the section on Oxana’s time in the Russian orphanage and prison. It explains her lack of fear in a way the show never quite managed to convey.
- Look for the fashion details. Jennings is a stickler for brands. He uses luxury items to show how Villanelle uses wealth as a suit of armor.
- Check out Jennings' other work. If you like his style, his journalism often carries that same sharp, observant edge.
The reality is that the Killing Eve book series stands on its own as a pillar of modern spy fiction. It’s less about the "cat and mouse" and more about two predators realizing they’re the only ones left in the woods. Go buy the first one. See for yourself why Luke Jennings was so adamant that his version of the story deserved a different fate.
