The unreliable narrator: how to build one

We're used to believing whoever tells the story. If the narrator says the house was peaceful, we picture a peaceful house. The unreliable narrator plays with exactly that trust: they tell a story, and the reader gradually realises things aren't quite like that. It's one of fiction's most fascinating techniques, and one of the easiest to get wrong.

Kinds of unreliability

Not every unreliable narrator is a liar. The most common forms:

• the liar: deliberately hides the truth, to protect themselves or manipulate;
• the self-deceiver: sincerely believes a version of events that suits them;
• the one who doesn't understand: a child, a naive person, someone without the tools to interpret what they see;
• the one who misremembers: time, trauma or nostalgia have warped their memory;
• the one with altered perception: illness, substances, obsession.

Each creates a different kind of gap, and a different effect on the reader.

The heart of the technique: the gap

The unreliable narrator works when readers perceive a gap between what is said and what happens. If they never notice, there's no unreliability: just an ordinary narrator and an ending that feels like a con.

At some point the reader must be able to say, "Ah, that's not quite how it was." And on rereading, they must find the clues were there.

How to plant clues

• Contradictions: the narrator says one thing and shortly afterwards tells something that doesn't fit.
• Other characters' reactions: everyone treats the narrator in a way that doesn't match the image they give of themselves.
• Details the narrator doesn't comment on: an empty bottle, an unopened letter, a name they avoid.
• Over-justification: someone who insists too much on their innocence raises doubts.
• Gaps in time: jumps exactly at the moments that would matter most.

A reason to lie

Unreliability must come from the character, not from the author's wish to surprise. Why does this narrator distort the story? Guilt, vanity, protecting someone, being unable to accept what happened? When the reason is clear, the distortions become consistent, and they reveal the character more than any description could.

The danger of the cheap twist

The most common mistake is using the unreliable narrator only for the surprise ending: the whole book told straight, then the last page reveals it was all false. Readers don't feel surprised, they feel cheated. The revelation works when it confirms suspicions the reader already had, not when it invents them out of nowhere.

First person, but not only

The unreliable narrator comes most naturally in first person, because the reader is inside a single head. But it can also be achieved in close third person: the narration adopts the character's point of view so closely that it shares their illusions.

Frequently asked questions

Are all first-person narrators somewhat unreliable?

In a sense, yes, because no one sees everything. But we speak of an unreliable narrator when the distortion is part of the book's design and the reader is invited to notice it.

How early should the reader realise?

It depends on the effect you want. Some novels reveal it early and build tension on doubt; others let suspicion grow until a final confirmation. Either way, the clues must be there from the start.

Can an unreliable narrator be likeable?

Yes, and it's often the most interesting case: readers grow fond of them just as they discover they're not being told everything.
