Decide what the narrator gets wrong
An unreliable narrator tells a story the reader cannot accept entirely at face value. That does not mean the narrator lies about everything. They might misremember an argument, overlook their own jealousy or insist that a risky choice was sensible. Their account can be accurate in many details while mistaken about the one detail that matters most.
Before planting clues, write down two versions of a key event: what the narrator believes happened and what you think happened. Then ask why the gap exists. Is the narrator protecting their pride, working with incomplete information or trying to persuade someone? A clear reason helps you choose clues that belong in this particular voice rather than scattering suspicious details at random.
Let small contradictions accumulate
A useful clue creates a question before it supplies an answer. Suppose a narrator says they barely noticed a guest at a party but can describe the guest’s coat, drink and exact departure. The details do not prove a lie. They do, however, invite readers to wonder why this person received so much attention. If the narrator later claims not to remember speaking to the guest, that earlier description gains weight.
Keep the scale of a contradiction suited to the story. A narrator who changes the time of a meeting by an hour may simply have a poor memory; one who repeatedly adjusts the time whenever their whereabouts matter gives readers a pattern to follow. Repetition with variation is often more persuasive than a single glaring error. Each clue should deepen the reader’s understanding, not just announce that a twist is coming.
Use what the narrator notices—and avoids
Narrators reveal themselves through selection. A character describing a family dinner might linger on the chipped plates and cold food while giving only a sentence to a sibling’s apology. That imbalance can suggest discomfort without requiring the narrator to name it. Likewise, a narrator who describes everyone else’s mistakes in detail but summarizes their own actions as doing what was necessary may be shaping the reader’s judgment.
To make such clues feel natural, connect them to the narrator’s habits. A person preoccupied with appearances may notice stains, posture and awkward silences. Someone afraid of being abandoned may track who leaves a room and how long they stay away. Those observations give the voice texture even before readers recognize what the narrator is avoiding.
Give readers another way to interpret events
Readers need evidence beyond the narrator’s conclusions. A friend’s hesitation, a returned letter or an object left in an unexpected place can offer a second interpretation. For example, a narrator may report that a friend agreed with their decision, then mention that the friend said little and stopped visiting. The narrator’s interpretation remains plausible to them, while the behavior leaves room for doubt.
Avoid making every other character a spokesperson for the truth. People can disagree, misunderstand or keep secrets of their own. Concrete actions work well because readers can weigh them without being told what to think. The aim is not to prove the narrator wrong on every page. It is to let readers notice a gap between what happened and what the narrator says it means.
Revise for fairness, not obviousness
On revision, read the draft once as someone who trusts the narrator and once as someone who doubts them. In the first reading, check that the account has emotional logic: could this person sincerely tell the story this way? In the second, mark every clue. If the answer depends on information introduced only at the end, plant an earlier trace. If every scene contains a suspicious correction or evasive remark, consider removing some. Readers need space to form their own judgments.
For a practical exercise, write a short scene in which a narrator explains why they missed an important meeting. Include one ordinary detail they remember clearly, one subject they pass over quickly and one response from another person that does not quite fit their explanation. Then revise the scene without adding a confession. The strongest clue may be the one the narrator shares freely, unaware that readers will understand it differently.
