Chekhov's Gun is the dramatic principle, attributed to Anton Chekhov in his letters, that a rifle hanging on the wall in act one must be fired by act three — and that if it will not be fired, it should not be hanging there. It is a rule about promises rather than about objects: conspicuous placement is a promise to the reader, and unkept promises read as sloppiness even when the reader cannot name what is wrong. The corollary matters as much as the rule, and is more often ignored: cutting the unfired gun is usually the better fix.
Also written as chekhov gun, chekhovs rifle.
Conspicuousness is the trigger
The principle applies to emphasis, not to existence. A novel can be full of unused objects, rooms and minor characters without breaking it, because nothing drew attention to them. The gun is loaded when the prose lingers: a detail given its own sentence, a character who explains something at length, an object the narration returns to. Anything the text works to make you notice has entered a contract.
The corollary does more work
In practice, most manuscripts have more unfired guns than missing payoffs, and the revision move is deletion rather than invention. Inventing a use for an abandoned detail tends to produce a contrived late scene; cutting the emphasis costs nothing and tightens the book. The exception is when the unfired gun is the more interesting object, in which case it may be signalling what the book should have been about.
Against over-application
Applied absolutely, the rule produces fiction in which every detail is functional and the world feels like a machine — a common failing in tightly plotted genre novels, where readers can predict the ending by cataloguing what has been mentioned. Texture requires some detail that goes nowhere. The distinction is between detail that is merely present and detail that is emphasised, and skilled writers deliberately emphasise things that pay off atmospherically rather than mechanically.
Relationship to the red herring
A red herring is a deliberately fired gun aimed at the wrong target — it must pay off, just not in the way the reader expected. This is why competent mysteries do not violate the principle when they mislead: the misleading detail does have a function, and the reader can see it afterwards. A detail that misleads and then turns out to mean nothing at all is not a red herring, it is an unfired gun with extra steps.
Where to see it working
The Cherry Orchard — Anton Chekhov
Chekhov's own practice is looser than the maxim attributed to him, which is worth knowing before treating it as law.
And Then There Were None — Agatha Christie
Every emphasised element pays off, which is precisely why the book is rereadable and why the rule is associated with mystery.
The Secret History — Donna Tartt
Emphasises a great deal that pays off atmospherically rather than mechanically, showing the rule's limits in literary fiction.
How it goes wrong
Inventing a late use for an abandoned detail instead of cutting the emphasis that promised it.
Applying it to every detail until the book has no texture and the ending is predictable by inventory.
Treating a misleading detail that means nothing as a red herring.
Assuming it is a rule of Chekhov's own fiction rather than a maxim from his correspondence.
