What Is a Red Herring? Examples in Mysteries (and How to Spot One)
Published June 10, 2026 Β· 2 min read
If you've ever been certain you knew the killer β only to be proven completely wrong β you've been fooled by a red herring. It's one of the most important tools in all of mystery storytelling. Here's exactly what it means, where the phrase comes from, and how to stop falling for them.
Red herring: the meaning
A red herring is a clue, character, or detail deliberately placed to mislead you β to draw your attention away from the truth. In a murder mystery, it's the suspicious person who didn't do it, the incriminating object with an innocent explanation, the confession that turns out to be a cover.
Red herrings aren't mistakes. They're the writer's craft. A mystery with no red herrings is just an announcement; the misdirection is what makes solving it satisfying.
Where does the phrase come from?
A "red herring" is a strong-smelling smoked fish. The popular story is that the pungent fish was once used to throw hunting dogs off a scent trail β so "drawing a red herring across the path" came to mean leading someone away from the truth. Whether or not the origin is literal, the meaning stuck: a false trail.
Famous red herrings (no major spoilers)
- Detective fiction loves the "most obvious suspect." Agatha Christie built her reputation on making you suspect everyone except the culprit.
- Thrillers and film use the ominous stranger β the character shot in shadowy lighting and scary music β who turns out to be irrelevant.
- Whodunit games plant physical red herrings: a bloody knife that belongs to the wrong person, a motive that's real but didn't lead to murder.
The pattern is always the same: something looks damning, your brain jumps to a conclusion, and the story quietly lets you run with it.
How to spot a red herring
You can train yourself to see through misdirection. Here's how:
- Notice when you're being pushed. If the story is working hard to make you suspect someone β lingering on their scowl, their secret, their alibi β be suspicious of the suspicion itself.
- Separate "suspicious" from "guilty." Lots of people have secrets, debts, and grudges. A secret is a motive to lie, not necessarily a motive to kill.
- Demand physical proof. Testimony misleads; evidence rarely does. A red herring usually falls apart the moment you ask, "Does the physical evidence actually require this person?"
- Explain every clue. The real solution accounts for the red herrings β it tells you why the innocent-but-suspicious details exist. If your theory leaves loose ends, you've probably grabbed a herring.
- Distrust the early confession. A confession in the first act is almost always a red herring: someone panicking, protecting another, or mistaken about their own guilt.
Practice spotting them yourself
Reading about red herrings is one thing; catching them under pressure is another. Our AI murder mysteries are built around exactly this skill β each case plants suspects who almost did it:
- Snowbound Pursuit is built around red herrings: parallel crimes make the first obvious theory feel tempting until the evidence narrows the path.
- The Womb House β rewards players who trust the architecture over what they're told.

Once you learn to feel the tug of a red herring, mysteries get even better. You stop being led by the nose and start reading the story the way the author really intended β as a fair fight between you and the truth.
