This Plot Device Will Make Your Readers Beg For More
Give your stories life and your readers an enticing read
This happened, then that happened, and it caused a whole bunch of other things to happen.
If your stories sound anything like that, they will feel and be lifeless.
Stories need suspense, and if it’s nonexistent, you will give up on it even before your reader gets a chance to read it. Or the rejection emails from agents will pile up with variations of: “Thank you for your submission, but your work is not a good fit for us at this time.” These are the worst because you have no idea what the problem really is.
“Not a good fit” can mean many things, but the first thing to check is whether you are creating suspense. Are your scenes boring, flat, and lacking mystery?
Since there are really only two kinds of stories in this world: the ones people turn to when they’re bored, and the ones they’ll drop everything to get back to, you want to be in the latter group. The best way to do that is to implement a plot devise that I’m going to share in this blog.
First a story . . .
After writing unsuccessfully for years, spending sleepless hours after work trying to write a novel publishers would want, I was one rejection away from packing it all in, from getting a real job, from letting the ink dry up for good. I’d lost the spark, or maybe I never had it to begin with. That night, walking through the city under a miserable drizzle, I ducked into a bookstore I’d never seen before. It was one of those ancient places, the kind that smells like dust and decaying paper, with shelves that groaned under the weight of forgotten worlds. A tomb of stories. And in a dusty corner, wedged between a leather-bound Milton and a stained manual on radio repair, I found it.
It wasn’t a book on writing. It had no title, no author on the spine. Just a slim, black volume with a single, strange symbol on the cover: a perfect circle with a crack running through it. Inside, the pages were filled with dense, handwritten script, detailing not a story, but a method. A forgotten plot device. It was a technique for creating a kind of suspense so potent, so deeply unsettling, it felt less like a literary tool and more like a dangerous secret. And now I had it. It would transform my writing forever.
Creating The Sympathetic Mirror
Okay, as I’m sure you guessed, the story above is not true (it’s an AI creation), but it demonstrates a plot device I call “The Sympathetic Mirror.” It does a few things that are absolutely necessary to capture the reader’s interest.
1. It creates suspense for the reader
2. It makes the reader an active participant in the story’s tension (I assume you are all writers and can picture yourself in the above story).
3. It builds a world that starts normal, feels completely, unshakeably real... and then something happens to change the character’s life forever.
The Sympathetic Mirror creates instant, unbearable suspense that leaves readers begging you for the next page. It’s a powerful tool because it preys on our most fundamental fear: the fear that our own reality isn’t as stable as we think.
Let me break down what I told AI to do to create the story. It did it perfectly, and you can too.
The First Principle: the anchor of the mundane
This is the foundation for everything, and it’s the step most writers get wrong. Before you can shatter your reader’s reality, you have to build it. And you have to make it feel absolutely, unequivocally, boringly real. Real psychological horror works by exploiting the trust we have in our everyday lives.
Most suspense stories jump the gun. A body is found on page one; a mysterious stranger arrives in the first chapter. You can’t do that. For The Sympathetic Mirror to work, you have to start with an almost painful commitment to the mundane. You have to lull your reader into a state of comfortable boredom. Describe your protagonist’s morning routine in excruciating detail. The specific gurgle of their coffee maker. The way they tap their toothbrush twice on the sink. The worn spot on their commuter bag. These aren’t just details; they’re anchors, chaining the reader to a world that feels as solid and predictable as their own.
You need to show the stability of this world. Let the reader feel the texture of an ordinary life, the dull rhythm of a boring job, the predictable conversations, the comforting weight of daily habits. The goal is to make the story’s world so mundane that the reader takes it for granted, just like the protagonist does. You’re making an unspoken promise: “This is the world. These are the rules. Everything is normal.”
A brilliant example of this is the first act of Gone Girl. Before the story explodes, the narrative goes to great lengths to establish the mundane reality of Nick and Amy’s marriage—the financial strain, the move to Missouri, the resentments hiding under the surface. It all feels so…normal, just like out own marriage. This deep investment in their flawed but believable life is what makes Amy’s disappearance so jarring. It’s not just an event; it’s a rupture in a reality we’ve been carefully taught to accept.
Another great one is the slow-burn dread in The Others. The film doesn’t start with ghosts; it starts with rules. The house must be dark, doors must be locked—all presented as practical necessities for children with a photosensitivity disorder. This establishes a strict, but mundane, reality. The horror comes not from breaking supernatural rules, but from the slow, creeping realization that the rules of reality are not what they seem.
The anchor of mundanity is your launchpad. The more solid you make it, the stronger the suspense will feel.
The Second Principle: the unexplained incursion
Once your anchor is set, you introduce the unexplained incursion. This is the first crack in the mirror. It has to be small. Subtle. It has to be something both the protagonist and the reader can easily dismiss. This isn’t the time for a ghost in the hallway. This is when a coffee mug is on the left side of the sink when the protagonist is certain they left it on the right.
This is where you start to prey on our shared psychological fears of losing our minds, of paranoia, of self-doubt. The incursion is a single, tiny detail that violates the world’s rules. A book that moves on its own. A door that’s unlocked when you know you locked it. A weird sound in a silent house. The trick is to make it deniable. The protagonist has to be able to rationalize it. “I’m just tired.” “I must have forgotten.” “It was probably just the wind.”
The reader, lulled by the mundane, will do the same. They’ll rationalize right along with the protagonist. But a tiny seed of doubt has been planted. This is so effective because it makes the reader an accomplice in gaslighting your main character. You’re not just telling them a story; you’re manipulating their perception of reality right alongside the protagonist’s.
We see this in films that master a slow escalation of dread. In a frightening movie I saw as a child (and never should have) Rosemary’s Baby, the horror doesn’t start with the devil; it starts with nosy neighbors, an odd-tasting smoothie, and a building sense of social unease. Each event is minor, easily explained away as the anxieties of a first-time mother. But together, they create a creeping paranoia that the world is conspiring against her, which, of course, it is. The creepy satanists have chosen her to have satan’s son.
Or think of The Machinist. Trevor Reznik’s mental plunge starts with small things: a mysterious game of hangman on his fridge, a new co-worker no one else has met. His shocking weight loss is an incursion on his own body. The film uses these illogical events to mirror his psychological collapse, making you question his sanity and everything on screen. Is he haunted, or is his mind unraveling? The power is in that uncertainty.
This works equally well in relationship stories, not just psychological thrillers or horror novels. Colleen Hoover does this well in It Ends With Us. Ryle doesn’t start out as a cruel woman-beater, hitting Lily on the first date. The first time he slaps her, it appears to be an accident. Both the audience and the character sweep the incident away. He loves her; he didn’t mean to strike her, but it leaves a hint of doubt that is disturbing and makes us realize that all might not be as perfect as we believe.
You’re foreshadowing a feeling, not an event. You’re dropping hints that reality itself is the untrustworthy character. You’re not scaring the reader with a monster; you’re scaring them with the idea that there are no monsters, and the world is just breaking apart on its own.
The Third Principle: the inversion of stakes
And that leads to the final, most powerful principle: the inversion of stakes. In a typical thriller, the stakes escalate externally. The hero has to find the bomb, then defuse it, then stop the next one. Here, the conflict turns inward. As the unexplained incursions pile up, the protagonist’s goal shifts. It’s no longer about solving an external mystery. It becomes a desperate, internal struggle to prove their own sanity.
The central conflict is no longer, “What is happening?” but “Am I going crazy and can I trust my own feelings?” This is the ultimate form of character jeopardy. The protagonist starts to distrust their own mind, testing reality by leaving objects in certain places or writing notes to themselves to prove they aren’t imagining things. At this stage, you turn their allies against them. Friends, family, colleagues—they all become voices of rational doubt. “You’re just working too hard.” “You’re not sleeping enough.” “Maybe you should talk to someone.”
Every attempt the protagonist makes to prove what’s happening only isolates them further and makes them look more unstable. And this is where the device gets truly terrifying. The reader, who’s been on this journey from the start, knows the protagonist isn’t crazy. They saw the mug move. They saw the paperclips appear. They saw him push her down the stairs. The suspense comes from a horrifying, dramatic irony: we know the truth but are forced to watch helplessly as the world closes in, convinced our hero is mad.
It’s the entire premise of John Carpenter’s In the Mouth of Madness. The protagonist is an investigator trying to find a missing horror novelist. His external goal is to solve the case. But as he enters a town that seems to come straight from the author’s books, his goal inverts. He’s no longer trying to find a man; he’s fighting to hold on to the fact that he’s a real person and not just a character. Very cool, actually.
Built in Suspense Means No Faking it
The Sympathetic Mirror is powerful. It’s powerful because it doesn’t just scare the reader with what’s on the page; it makes them question the very ground they stand on. This means you are not creating contrived conflict. It’s coming naturally from the story and reader expectations.
This device taps into a primal fear that our world is not what it seems. The beauty about this fear is that it’s true. At any moment, our perfectly orchestrated life can change with a job loss, the death of a loved one, an accident, a pandemic, a natural disaster. We really are victims of circumstance. So, we are perfectly willing to go along with whatever event cracks a fissure in our character’s perfect life.
To use this plot device, follow the three steps:
First, build an unshakeable, mundane reality—The Anchor of Mundanity.
Second, introduce a small, deniable crack in that reality—The Unexplained Incursion.
And third, turn the conflict inward, making the character’s fight for their own sanity the real story—The Inversion of Stakes.
Simple, and I didn’t need that magical black book with handwritten notes to discover the secret. My secret is learning from the many brilliant authors who have written great stories. But it sure would be awesome if it were true, wouldn’t it?
