Writer’s Prompt: Behind the Floorboard: A Psychological Thriller Short Story

A grieving daughter, a forbidden house, and a diary entry that changes everything. Will Stacy escape the man who ruined her family?

The Last Will of Sarah Watson

The floorboard groaned, a terrifying shriek in the empty house. Stacy held her breath, her heart hammering against her ribs like a trapped bird. Ralph was supposed to be at the lumberyard until five, but his unpredictable temper made him a ghost that could materialize at any moment.

She reached into the dark, dusty void beneath the wood. Her fingers brushed velvet.

Pulling out the small, leather-bound journal, she wiped away the grime. This was it. The single item her mother, Sarah, had begged her to retrieve if the worst ever happened. When Sarah died of a sudden, unexplained “heart attack” three weeks ago, Ralph had immediately barred Stacy from the house, changing the locks. He hadn’t counted on the spare key Sarah had smuggled to her months prior.

Stacy leaned against the closet wall, her knees shaking as she cracked the spine. The handwriting was unmistakably her mother’s, though the normally elegant cursive was jagged, frantic. She flipped to the final entry, dated the night before Sarah died.

Ralph is trying to kill me. Be my revenge if I die.

The air left Stacy’s lungs. A cold sweat broke out across her neck. Before she could process the horror of the words, the heavy front door downstairs clicked.

“Stacy?” Ralph’s booming voice echoed up the stairwell, closer than it should be. He was already in the hallway. “I saw your car, kiddo. We need to talk.”

Heavy footsteps began to ascend the stairs, deliberate and slow. Stacy looked at the open floorboard, then at the window, and finally at the journal in her hands. There was nowhere to hide, and no time to run.

Finish the Story

How does Stacy confront Ralph? Does she escape through the window, or face him with the truth? The pen is in your hands—how does her revenge begin?

Writer’s Prompt: A Femme Fatale’s Deadly Request: Neo-Noir Fiction

She had a face like an angel, a purse full of blood money, and a dead man’s name on her lips.

The Red Circle

The dart bit into the wall, a fraction of an inch from the bleeding eye of the red marker circle. I was reaching for the third feather when the frosted glass of my office door rattled.

Then she walked in. One hundred and twenty pounds of absolute dynamite, wrapped in a trench coat that cost more than my monthly retainer. Her eyes were a cold, calculated storm. She didn’t look at the peeling wallpaper or the dust dancing in the afternoon light. She looked straight at me. She knew exactly what I was. The papers called me a butcher with a badge; a PI who treated bones like kindling.

“Mr. Seroni,” she said. Her voice was like silk dragging over gravel.

“The sign says open,” I replied, leaning back till my chair groaned. “But the look on your face says trouble.”

She didn’t waste time. She reached into her leather purse, pulled out a thick, banded stack of hundreds, and dropped it onto the desk. It landed with a heavy, dead thud. Right on top of my old racing forms.

“My husband,” she whispered, leaning in. The scent of expensive jasmine and cheap desperation filled the space between us. “I need him gone. Permanently. And I was told you don’t mind getting your hands dirty.”

I looked at the cash. It was enough to buy a new life, or at least a better grade of bourbon. Then I looked at her. Beautiful. Lethal. A fuse waiting for a match.

“Murder is a heavy lift, lady,” I murmured, my hand drifting toward the desk drawer where my .38 slept.

She smiled, a sharp, humorless edge. “I think you’ll find you have the leverage.”

How does Matt’s story end? Does he take the blood money, or does the lady find out just how violent Seroni can truly get? Write the final twist and finish the story.

Writer’s Prompt: Neon Betrayal: A Gritty Noir Flash Fiction Story of Revenge

The rain didn’t wash away the filth of the city; it just made the betrayal slicker.

Writer’s Prompt

The rain in this city doesn’t wash anything clean; it just makes the filth slick.

I sat in the dark of the Neon Parrot, watching the amber liquid in my glass catch the pulsing light from the street. My trench coat was still damp, heavy with the scent of cheap tobacco and regret. I was waiting for Julian.

Three years ago, Julian was the partner who had my back. Two years ago, he was the man who left me to rot in a state penitentiary for a heist he orchestrated. Today, he was just a target.

The door chimed. Julian walked in, flanked by two gorillas in tailored suits. He hadn’t changed, still wearing that arrogant, million-dollar smile. But his eyes went cold when he spotted me sliding out of the booth.

“Leo,” he breathed, his hand instinctively twitching toward his jacket lining. “I heard you got out.”

“Early biological release,” I said, my voice like gravel. “They said I was rehabilitated. I told them I had unfinished business.”

I didn’t give his hired muscle time to react. I pulled the snub-nosed .38 from my pocket and leveled it at his chest. The bartender vanished behind the counter. Julian’s smile evaporated, replaced by the pale sheen of terror.

“Leo, wait, it wasn’t my call—”

“Save it.” I cocked the hammer. The click sounded like a thunderclap in the sudden silence of the bar.

But then, a shadow moved in the reflection of the mirror behind Julian. A cold barrel pressed firmly against the back of my own neck. A familiar, perfume-scented voice whispered in my ear: “Drop it, Leo. He’s with me now.”

It was Clara. The woman I thought was waiting for me.


How Does the Story End?

Your Turn: Does Leo pull the trigger anyway, taking Julian down with him? Does he turn the gun on Clara, or lay it down, defeated by a double betrayal? Finish the story in the comments below.

Writer’s Prompt: A Writer’s Revenge Turns Deadly in This Gripping Noir Flash Fiction

Lacy took her professor’s writing advice literally. Now, a real-life killer is inside her apartment.

The Devil’s Editing

The glossies felt heavy in Lacy’s hands, slick with the scent of cheap developer fluid and betrayal. In the harsh glare of her desk lamp, Professor Vance didn’t look like the campus deity who had casually crushed her literary dreams. He looked like an old man caught in a sordid clench with an undergraduate who was barely old enough to vote.

“Become the character,” he’d sneered during office hours, dismissing her manuscripts as bloodless. “Write from experience.”

So, she had. She bought the snub-nosed .38, learned the heavy kick of gunpowder at the indoor range, and wore a trench coat that smelled of rain and desperation. She had tracked him through the neon-soaked alleyways of the city, intending to prove she had the grit to be a real noir writer. Instead, she’d stumbled onto a career-killing scandal.

Blackmail was a classic trope. She could ruin him with a single envelope. It was the perfect ending to her real-world first chapter.

Then, the floorboards in the hallway groaned.

Lacy froze. The click of her apartment deadbolt was a sound she knew intimately, but she hadn’t turned the key. The door swung open, casting a long, jagged shadow across her linoleum floor.

A silhouette stood in the frame. The scent of familiar, expensive cologne drifted into the room, cutting through the smell of her stale coffee. A hand slipped into a dark coat pocket.

“A good writer always knows when to kill off a character, Lacy,” a smooth, cultured voice echoed from the dark.

Lacy’s fingers gripped the cold steel of the .38 hidden beneath the photos on her desk. She had the weapon, but did she have the nerve?


What happens next? Does Lacy pull the trigger, or does the Professor write her final chapter? Write the ending and finish the story.

Writer’s Prompt: A Waterfront Heist Goes Deadly Wrong in This Dark Noir Thriller

Two small-time crooks think they’ve found a ticket to paradise in a stolen shipping crate, but the docks only trade in blood and betrayal.

Writer’s Prompt

The rain on the windshield tasted like rust and cheap coffee. Inside the beat-up Honda, the heater was dead, and the dark harbor smelled of dead fish and diesel.

Sal jabbed a cold slice of pepperoni toward the docks. “Watch for the orange crate, Tony. It don’t have TVs. It’s filled with cash and smack. That’s the payload.”

Tony chewed his crust, his eyes locked on the freighter’s crane. “We leave the junk,” he mumbled, steam rising from his mouth. “We take the green, we don’t count it, and we scram for Arizona. I can’t take another winter of this cold.”

An hour later, the docks were a graveyard of shadows. They slipped past the sleeping watchman, the tarmac slick beneath their boots. In the belly of Warehouse 4, the orange crate sat waiting—a neon tombstone in the dark.

Sal wedged the crowbar beneath the splintering pine. Crack.

The wood gave way with a sound like a breaking bone. Sal reached inside, his fingers tearing through packing peanuts. He pulled his hand back, but it wasn’t holding bricks of hundreds or bags of powder.

It was a digital timer. 00:04. 00:03.

From the shadows behind them, a heavy bolt-action clicked.

“You boys are late,” a voice rasped.

Sal froze, crowbar raised. Tony’s hand crept toward his jacket pocket, his fingers slick with sweat. The timer blinked down to one.


Over to You…

How does Tony and Sal’s desperate gamble end? Do they dive for cover from the blast, face the gunman in the dark, or does the timer reveal a different trap entirely? Finish the story in the comments below!

Writer’s Prompt: The Blackmail Lens: A Gritty Noir Flash Fiction

Ernie Potter has the city’s biggest scandal in his viewfinder, but a shadow in the rearview is closing in for the kill.

Writer’s Prompt

The Last Frame

The rain didn’t wash the city clean; it just turned the grit into a slick, black sludge. Ernie Potter sat in the belly of his rusted Toyota, the scent of stale coffee and cheap tobacco his only company. Through the long lens of his Nikon, the world was reduced to a grainy rectangle of high-stakes indiscretion.

Tyler Dexter IV—the city’s golden boy with a platinum pedigree—was draped over a girl who looked like she’d just traded a prom dress for Prada. They lingered under the glow of the Michelin star, a picture-perfect portrait of a scandal worth six figures.

Click. Click. Ernie felt the rush. This wasn’t for a client; this was his retirement fund. One more shot of the hand on the waist, and he’d have enough leverage to bury Dexter or buy a one-way ticket to a beach where nobody knew his name.

Then, the rearview mirror caught a flicker of movement.

A shadow detached itself from the brickwork across the street. A mountain of a man in a tailored overcoat, moving with the heavy, rhythmic gait of a professional wrecker. He wasn’t looking for a taxi. He was looking at the Toyota.

Ernie’s heart hammered against his ribs like a trapped bird. The big man was twenty yards out, his hand dipping into a deep pocket.

Dexter and the girl turned toward the restaurant door. This was the shot. The money shot. If Ernie peeled out now, he had nothing but a blurry silhouette. If he waited three seconds, he had the world by the throat.

The shadow was ten yards away now. Ernie saw the glint of brass knuckles—or maybe a barrel.

What happens when the shutter clicks? Does Ernie get his payday, or does the camera become his headstone? You decide how the roll ends.

Writer’s Prompt: Shadow in the Park: A Gritty Noir Flash Fiction Challenge

Wren Prizzi has the killer in her sights, but in the heart of the dark woods, the hunter just became the prey.

Writer’s Prompt

The humidity in the park clung to Wren Prizzi like a cheap suit she couldn’t return. Every step into the dense brush felt like wading through wet wool. She’d trailed the Phantom for six blocks, watching that distinctive, uneven gait—the predator who had eluded the precinct for months.

Then, the shadows swallowed him.

Wren stopped, her lungs burning with the scent of damp earth and rot. The silence was a physical weight until the voice cut through it, cold and dry as bone.

“You looking for me?”

She spun. He was a pillar of darkness, 6′2′′ of jagged edges and lethal intent. He didn’t have a weapon—just a silk scarf pulled taut between two massive, gloved hands. The fabric groaned under the tension.

Wren’s hand flew to her holster, her fingers brushing the cold checkered grip of her Smith & Wesson. But her jacket caught. A split-second snag. A heartbeat of failure.

He lunged.

The scarf didn’t go for her neck; it went for her eyes. Wren felt the rough silk snap across her face, blinding her as she was driven backward into the mud. She kicked out, her heel catching something solid, but he was a mountain of muscle pressing down. Her gun cleared the holster, but his weight pinned her wrist to the muck.

The metal felt a mile away. Her vision was a blur of black silk and moonlight. She could feel his hot, ragged breath against her ear as he whispered, “Close your eyes, Prizzi. It’s easier that way.”

Her finger found the trigger. He found her throat.

The hammer cocked with a metallic click that sounded like a funeral bell.


Finish the Story

Does Wren pull the trigger in time, or does the Phantom finally claim the one hunter who got too close? The city is waiting for an answer. How does this standoff end?

Writer’s Prompt: The Keystroke Killer: A Noir Tale of Digital Blackmail

Lenny Snookers thought he found a golden ticket in a millionaire’s infidelity, but he forgot that in a world of digital surveillance, the shadows are never empty.

Writer’s Prompt

The flashbulb of Lenny’s camera felt like a heartbeat—quick, artificial, and liable to stop at any second. From the shadows of the fire escape, Lenny watched Josh Carson whisper into the ear of a woman who wasn’t his wife. Carson, the man who turned a PDF reader into a digital vacuum, was worth nine figures. To Lenny, he was worth a one-way ticket to a beach where the only “keys” were in the ignition of a boat.

Lenny pulled the SD card and tucked it into his breast pocket. He could take the photos to Cindy Carson and collect his meager hourly rate, or he could take them to the Journal and burn Carson’s empire to the ground. But then there was the third door: the private exchange. A man like Carson would pay millions to keep his digital theft—and his mistress—out of the light.

The Caribbean sun was practically tanning Lenny’s face until the cold steel of a barrel pressed against the base of his skull.

“The cloud sync is a beautiful thing, isn’t it, Lenny?” a voice rasped. It wasn’t Carson. It was the “arm candy.” She wasn’t looking at Carson anymore; she was looking through the viewfinder of a sniper scope leaning against the brickwork. “Josh doesn’t just steal keystrokes. He buys people who track the people who track him.”

She reached out a gloved hand. “The card. Now. And maybe you walk away.”

Lenny felt the weight of the card against his chest. He knew two things: she was lying about letting him walk, and his backup camera was still recording from the trash bin behind her.


Finish the Story

Does Lenny hand over the card and pray for mercy, or does he lunge for the fire escape, betting his life on the second camera he left behind? The ending is in your hands.

Writer’s Prompt: The Bartender’s Dilemma: A Gritty Noir Flash Fiction

Matty knew every secret in the city, but the one he heard tonight might be his last.

Writer’s Prompt

The neon sign of the Lucky Dragon hummed with a low, electric anxiety that matched the vibration in Matty Beekins’ chest. To most, the Dragon was a dive; to Matty, it was a confessional where the wine was cheap and the sins were heavy.

He’d mastered the art of being part of the furniture. He polished the same spot on the mahogany bar until it shone like a dark mirror, catching the reflection of Nick Bena and Paul Costello huddled in the corner booth.

“The motorcade slows at the Fourth Street bottleneck,” Nick whispered, his voice cutting through the jazz playing on the overhead speakers. “One shot from the parking garage. The Mayor’s a ghost before the sirens even start.”

Paul nodded, checking his watch. “Simple. Clean. We’re in and out.”

Matty felt the cold sweat prickle his neck. He liked Nick. Nick tipped well and asked about Matty’s mother. But the Mayor? The Mayor had kids. If Matty stayed silent, he was the getaway driver in spirit. If he whispered to the precinct, he’d find himself at the bottom of the East River with concrete slippers before the ink on the police report was dry.

He gripped the rag until his knuckles turned white. He had ten minutes before they walked out that door to set the wheels in motion. His phone sat heavy in his pocket, a loaded gun of a different variety.

Matty looked at the back door, then at the rotary phone behind the bar, then back at the booth. The choice was a razor blade, and he was already bleeding.


How does Matty escape the noose?

Does he orchestrate a “clumsy” accident to delay them? Does he make an anonymous tip that backfires? Or does he find a third way that keeps his skin intact and the Mayor alive? The pen is in your hands—finish Matty’s story.

Writer’s Prompt: Left at the Altar: A Dark Noir Tale of Revenge and Mystery

One word on a glowing screen changed Sarah’s heartbreak into a hunt for survival: Run.

Writer’s Prompt

The gym smelled of stale sweat and old regrets. Sarah Leveno’s knuckles were raw inside her wraps, but she didn’t stop. Thud. Thud. Thud. Each impact wasn’t just a workout; it was a rhythmic erasure of Joe Parker. Joe, who had promised a forever that expired ten minutes before the “I dos.” Joe, who had vanished into the humid city night, leaving her standing in ivory silk like a monument to a dead hope.

The neon sign outside the basement gym flickered, casting a bruised purple hue over the heavy bag. Sarah leaned in, her breath coming in ragged stabs. She wasn’t just hitting the bag anymore; she was hitting the memory of his smirk, the way he smelled like expensive bourbon and cheap lies.

“He’s not worth the cardiac arrest, Sarah.”

She froze. The voice came from the shadows near the lockers. A man stepped forward—Detective Miller. He looked like he’d slept in his car and lived on black coffee. He held out a manila envelope, damp from the rain outside.

“We found his car,” Miller said, his voice dropping to a gravelly whisper. “Engine running. Door wide open. His phone was on the dashboard with a draft text addressed to you. Just one word: Run.”

Sarah felt a chill that had nothing to do with the gym’s failing heater. She looked at the envelope, then at the heavy steel door at the top of the stairs. A shadow had just eclipsed the sliver of streetlamp light beneath the frame.

The bag swung gently between them, a dead weight in the dark.


Finish the Story

Is Joe a victim, or is he the one Sarah should be running from? Who is standing behind that door? The ending is in your hands—tell me, what happens when that door swings open?
