What is a red herring?

A red herring is a detail that is placed in a story to lead the audience toward the wrong conclusion. A suspicious neighbour, a bloodstain with an innocent explanation, a letter that means something other than what it appears to mean. It is misdirection: not a lie, but a truth aimed in the wrong direction.

Where the name comes from

The phrase is usually explained with a story about dragging a cured, strong-smelling fish across a trail to throw dogs off the scent. Whether anyone actually did this regularly is disputed — the phrase caught on in the nineteenth century as a figure of speech for a deliberate distraction, and the literary meaning grew from there. Either way the image is the useful part: something strong-smelling placed across the path you were following.

The fair one and the cheat

This is the distinction that matters, and it is the one most people miss. A fair red herring gives you accurate facts and lets you draw the wrong conclusion from them. The neighbour really was out that night — he was having an affair, not committing a murder. When the truth arrives, you reread the clue and it still holds.

A cheat withholds or falsifies. The narration says the door was locked, and later the author needs it to have been open. Readers forgive being outwitted and never forgive being lied to, and the difference between the two is audible in how a book gets talked about afterwards.

The sharpest version of this device sits inside the narration itself, where the person telling you the story is the misdirection — a related but distinct technique covered in what is an unreliable narrator.

The usual shapes

The obvious suspect. Rude, secretive, has a motive and no alibi. So clearly guilty that experienced readers discount them immediately — which is itself exploitable.

The innocent secret. Someone is hiding something, and it is real, and it is irrelevant. The most elegant form, because nothing has to be taken back.

The emphasised object. A thing the prose lingers on, which turns out to matter far less than the thing mentioned once in passing.

The wrong frame. Everyone, including the detective, assumes the question is who. The actual question was when, or whether a crime happened at all.

How to spot them as a reader

You are not meant to win, and chasing every detail is a bad way to enjoy a book. But a few habits help if you want to play along:

Notice what the author is spending attention on, not what the characters are. Pages are expensive; a detail given a whole paragraph is doing some kind of work, even if that work is distraction. Ask who benefits from you looking in a particular direction. And pay attention to the quiet, pleasant, structurally boring characters — the ones with nothing to contribute and no screen time are sometimes the point.

Then notice how differently the whole thing reads the second time, when the misdirection no longer works and you can see the machinery instead. It is one of the main pleasures of going back to a book you already know the answer to — the case we make in why rereading books is worth it.

If you are writing one

Three rules cover most of it. Give the false lead its own real reason to exist — a character who is only in the book to be suspected feels like a prop. Resolve it. An abandoned red herring is just a plot hole; the reader needs to learn what that bloodstain actually was. Plant the truth before you hide it. The real clue should already be on the page, underplayed, so the reader can be annoyed at themselves rather than at you.

And use fewer than you think. Four suspicious characters and six misleading objects do not create suspense, they create fog — the reader stops forming theories at all, which means they stop caring who did it. Misdirection only works when the reader has committed to a wrong answer, and commitment requires a shortage of options.

Where to see it done well

Agatha Christie is the obvious school, and The Murder of Roger Ackroyd is the famous argument about where the line sits. Among out-of-copyright books, Wilkie Collins's The Moonstone is full of fair misdirection and largely invented the English detective novel, and Arthur Conan Doyle's Holmes stories run the device constantly in miniature. If this is new ground for you, thriller and mystery books for beginners is a starting map.

One last thing worth saying: misdirection is the most sociable device in fiction, because being wrong out loud is funnier with company. Half the pleasure of a mystery is telling somebody your theory and watching it collapse. That urge is why we built Arwy, our Android reading and writing app, to connect you with other people reading the same book — though if you would rather solve it alone with no risk of overhearing a spoiler, reading in silence is a perfectly respectable choice and we are the wrong tool for it.
