Your Red Herring Should Solve the Case
Every amateur red herring is the same cheat: a suspicious thing planted for no reason except to waste the reader’s suspicion. The threatening letter nobody wrote. The shadowy stranger who never matters. When the reveal comes, the thing pays back nothing, and fair-play readers feel it — the author raised a question and answered it with a shrug.
The fix isn’t to hide better. It’s to make the misdirection honest. Give your obvious suspect a secret that’s real. People hide things — an affair, a debt, a brother the law wants. If your suspect acts guilty, let it be because he’s guilty of something. Just not the murder. True facts, wrong conclusion: that’s a herring with a clear conscience.
Arthur Conan Doyle runs the double duty beautifully in The Hound of the Baskervilles. Barrymore, the butler, tiptoes through the manor at midnight, holding a candle to the window. “I was doing no harm, sir. I was holding a candle to the window.” Suspicion lands on him instantly — and it’s justified. He’s concealing something. The candle is a signal to his wife’s brother, Selden, the escaped murderer hiding on the moor. Real secret, wrong crime.
And the dead end dead-ends into the answer. Selden flees across the moor in Sir Henry’s cast-off suit, and the hound — scent-laid on Sir Henry’s stolen boot — runs the wrong man down. Holmes kneels over the body and names it: “Then the clothes have been the poor devil’s death.” The mistake proves the method: a real animal, trained on the baronet’s scent, aimed at the baronet. The herring the butler lit becomes the clue that convicts the killer.
Three mechanics make a herring pay double. Give the suspect a true secret of the wrong size — real enough to produce guilty behavior, so the reveal explains the behavior instead of apologizing for it. Wire the herring into the solution: its exposure must hand the detective a fact the case needs — a method, an alibi, a connection. If the plot survives unchanged when the herring resolves, it was decoration. And let the reveal re-price the scenes — every suspicious beat was honest; the reader did the misreading. That’s what makes it fair play.
Find your least convincing red herring — the suspect who acts suspicious for no reason you can defend. Write one sentence naming what they’re actually hiding: something true and embarrassing, but short of murder. Then ask what fact its exposure hands your detective. If the answer is nothing, change the secret until its discovery breaks the case open.
