There is a moment in almost every mystery novel where someone leans across a table, fixes the detective with a look of wounded dignity, and says: "I was nowhere near the library that evening. I was at home. Alone."
And the reader thinks: you did it.
A red herring is a deliberate false clue meant to mislead or distract readers (or listeners) from the truth. The phrase itself has a storied history, famously coined in 1807 by journalist William Cobbett as a colourful tale about using a smoked fish to throw hounds off a trail. In this article, we’ll trace the origins of the term, share some playful examples, and explain why good writers use red herrings without making readers feel cheated.
Let me paint you a picture.
You're reading a novel. The plot is ticking along nicely, the detective is being detectivey, and then you turn a page and walk into the house. And something happens. The hairs on the back of your neck do a little shimmy. The house isn't just where the story is happening — it is the story. It watches. It remembers. It has opinions about you, and they're not entirely flattering.
Every genre has its icons. Romance has its brooding dukes. Thrillers have their maverick agents with a drinking problem and a past. But cosy mysteries? We have something far more interesting: a retired spinster who knits and sees everything, a fussy Belgian with a moustache that could tell its own story, and an assortment of amateur sleuths who absolutely should not be solving murders but somehow always do.
