'The Sinner' by Petra Hammesfahr is a deep dive into this. The narrator, Cora, has committed a very public, violent act but has no memory of why. The entire book is the process of uncovering her own repressed memories and trauma. Her unreliability is total—she doesn't know her own motives. The mystery is internal archaeology, and the reader learns the truth as she does, often horrified by what's excavated. It's less about plot twists and more about the devastating psychological reasons behind a single, inexplicable action.
For a fun, meta take, 'The Word Is Murder' by Anthony Horowitz features the author himself as a bumbling, fictionalized narrator alongside detective Daniel Hawthorne. Horowitz-the-character is constantly getting details wrong, jumping to conclusions, and misinterpreting Hawthorne's methods. The unreliability comes from his ego and his desire to shape events into a satisfying narrative for his book. It's effective because it feels authentic; a writer in the middle of a real case would be an unreliable filter, prioritizing story over strict accuracy. The mystery is solved despite the narrator, not because of him.
For a classic locked-room mystery with a twist, 'The Decagon House Murders' by Yukito Ayatsuji. The narrators are the members of a university mystery club stranded on an island. The unreliability is communal; they're all fans of detective fiction, prone to seeing their situation through the lens of a classic whodunit. They theorize wildly, suspect each other based on literary tropes, and their amateur deductions often lead them astray. The narrative plays with their self-aware, genre-savvy perspectives to misdirect the reader. You're trying to solve a real murder alongside characters who are treating it like a fictional puzzle, which creates a fascinating meta-layer of deception.
I have a soft spot for 'The Likeness' by Tana French. While the detective, Cassie Maddox, is the narrator, her undercover assignment forces her to become an unreliable narrator to herself. She must inhabit the identity of a murdered girl so completely that her own memories and personality begin to blur with the victim's. The unreliability stems from this deliberate, psychological fusion. Can she trust her own intuition, or is it the dead girl's? The mystery becomes internalized, and the line between detective and victim, between truth and performance, dissolves in a really fascinating way.
Honestly, I think we give some books too much credit for having an 'unreliable narrator' when it's just a cheap twist at the end. A truly effective one makes you complicit in the unreliability. You start making excuses for the narrator, believing their justifications, right up until the moment you can't. 'The Secret History' by Donna Tartt isn't a murder mystery in the traditional sense, but Richard's narration, with his longing to belong and his obvious hero-worship, beautifully obscures the moral rot at the center of the group. You see what he wants you to see, until you're forced to see the truth.

I quit and dipped. City threw a parade.
Only Jenna Blake—my oh-so-gifted junior who claimed she could "see through killers' eyes"—lost it.
At her celebration banquet, she went full drama queen:
"I owe everything to Kate Mercer. Please, bring her back!"
I laughed. Cold. Not happening.
Last time around, I was the hotshot detective. But every clue I found? She dropped it first like she read my mind.
People started saying I was washed.
So I went all in—three months, no sleep, cracked a massive trafficking ring. Led the raid myself.
She beat me there. Again. Place was cleaned out.
Boom. She's the city's golden girl.
I'm the clown with no game.
Pressure got ugly. My head snapped. I died chasing the last scumbag.
Then—bam. I woke up. Same day. Raid morning. Round two.

Alice Warren was the daughter of two famous murderers. Her fate, which was full of bad luck, finally met its end when the Le Blancs adopted her. The Le Blancs were good and kind people; they helped the poor, donated to charities, and built an organization for the orphans called UNITY.
Alice was already contented with her life, but all of her beliefs and luck crumbled down when she entered Saint Clair Academy, and the series of accidents and deaths started again. Of course, it did not help that an irritating genius artist, Thomas Saint Clair, was always at her tail.
Now that the number of dead bodies increased, Alice had to investigate whether the accidents were just lousy luck full of coincidence or carefully planned-out murders.

Shari Lapena's 'The Couple Next Door' uses a more grounded unreliability. Every character lies, not necessarily to the reader directly, but to the police and each other. You're following multiple people hiding mundane but damaging secrets (affairs, debts) that complicate the central crime of a missing baby. The unreliability is in the gaps between what they say aloud and what they think. It's less psychological thriller, more domestic suspense built on a foundation of white lies.
Okay, real talk: how many of you, after reading a bunch of these, start over-analyzing your own memories and wondering if you're an unreliable narrator of your own life? No? Just me? Cool, cool.
I'd argue 'The Name of the Rose' qualifies. Adso of Melk is recounting events from his youth as an old man, so memory and the passage of time filter everything. Plus, his perspective is limited by his own innocence and the dogmatic worldview of his time. The mystery isn't just about the murders, but about the reliability of history and narrative itself.
What defines 'unreliable' though? Is it just amnesia and alcoholism, or can it be ideological? In 'The Secret History', the narrator, Richard, is so enamored with the elitist Greek class that his retelling of the events leading to murder is steeped in romantic, tragic nostalgia. He's an unreliable historian of his own life,美化ing the darkness.
unreliable narrators in mystery novels are my absolute jam. One standout is 'Gone Girl' by Gillian Flynn, where Nick and Amy's perspectives constantly keep you guessing—just when you think you've figured it out, the rug gets pulled out from under you. Another masterpiece is 'The Silent Patient' by Alex Michaelides; Alicia’s silence and Theo’s obsessive unraveling of her past create a chilling dance of doubt.
For a classic, 'The Murder of Roger Ackroyd' by Agatha Christie flips the genre on its head with a narrator who’s anything but trustworthy. More recently, 'The Girl on the Train' by Paula Hawkins uses Rachel’s alcohol-induced memory gaps to muddy the truth. And if you want something with gothic flair, 'Rebecca' by Daphne du Maurier features a narrator whose insecurities color every recollection. These books don’t just tell a story—they make you question reality itself.
