Writer’s Prompt: Flash Fiction: The Murderer in the Next Office

She spent six years hunting a monster, only to find him sitting in the very next room.

The DNA of Deceit

The cardboard box sat on Detective Ellen White’s desk, smelling faintly of cellar mold and old copper. Inside lay a single, mud-encrusted barrette and a typewritten note: The man who took Linda Lomes in 2020 still wears a gold shield.

For six grueling years, Linda’s face had haunted Ellen’s mornings and wrecked her nights. Fifteen years old, walking home from school on a rainy Friday, vanished into thin air. Ellen had chased ghosts, dead ends, and false leads until her department deemed the case cold.

But holding the barrette, Ellen felt the familiar, obsessive fire flare to life. The note was specific. The evidence was damning. But the realization that followed was a physical blow that left her breathless.

The gold shield. The specific scheduling details only an insider would know.

Through the blinds of her office, Ellen looked into the adjacent room. Chief of Detectives Larry Curtis was laughing at his desk, nursing his morning coffee in a styrofoam cup. Her boss. The mentor who had comforted Linda’s grieving mother on television.

Ellen’s heart hammered against her ribs. She didn’t need a warrant yet; she just needed a baseline. A single stray hair from his chair, a fingerprint from his discarded water bottle, or the saliva on that styrofoam cup currently sitting in his trash can.

She stood up, smoothing her jacket, her hands trembling with a mix of terror and anticipation. The murderer wasn’t hiding in the shadows of the city. He was right next door.

Ellen stepped into the hallway, her eyes locked on the coffee cup. Larry looked up, his smile fading into a sharp, calculating gaze. “Morning, Ellen,” he said, his hand hovering near his desk. “You look like you’ve finally seen a ghost.”

How does Ellen get the DNA without tipping off the Chief? Does she walk into a trap? Write the final scene and close the case.

Writer’s Prompt: Noir Flash Fiction Story: The Deadliest Retainer

Two rival private eyes, one massive bounty, and a gangster who wants them both dead. Who pulls the trigger first?

The Last Contract

The rain over the city didn’t wash away the grime; it just made it slick.

Leo adjusted the collar of his trench coat in the shadow of the abandoned textile mill. Across the cracked concrete, Elena leaned against a rusted girder, her silhouette sharp, the amber ember of her cigarette glowing like a low-tier warning light.

They were the best independent investigators in the city, which meant they usually got in each other’s way. Tonight, they had the same client.

“He called you too, huh?” Elena’s voice cut through the downpour, cool and steady.

“Sal don’t make mistakes, Elena. He makes moves,” Leo replied, keeping his hand pocketed, fingers brushed against the cold steel of his revolver.

Salomón “The Saint” Rossi had a problem: a leak in his organization that had cost him a multi-million dollar shipment. He had summoned both PIs to his penthouse three hours ago. But the meeting wasn’t to hire them for a routine asset recovery. Sal had placed a thick, leather-bound briefcase on the mahogany desk, snapping it open to reveal neat stacks of banded hundred-dollar bills. Half a million.

“The leak is gone, but the liability remains,” Sal had smiled, teeth gleaming like polished ivory. “Only one of you walks away with the retainer. The one who ensures the competition… retires permanently.”

Now, in the hollow carcass of the mill, the tension stretched to a breaking point. Elena tossed her cigarette into a puddle. It hissed and died.

“Half a million buys a lot of fresh starts, Leo,” she murmured, her posture shifting into something coiled and lethal.

“I was thinking the exact same thing,” Leo said.

A floorboard creaked above them. A shadow shifted. Suddenly, they both realized they weren’t alone.

How does the standoff end? Does one PI turn on the other, or do they realize Sal set them both up? Write the final scene and close the case.

Flash Fiction: Anne Vincent Had One Rule: Hurt a Woman and She Comes for You

Some detectives find the truth. Anne Vincent forces it to look her in the eye.

Anne Vincent didn’t believe in omens, but the night she took the pro bono case the streetlamp outside her office flickered like a dying heartbeat. She lit a cigarette, watched the orange tip glow in the darkness, and told herself she wasn’t getting soft. Not yet.

Her client, Marcy Delgado, looked like she had run out of places to hide. The bruises on her forearms were the faint yellow of old storms, but the ones in her voice were fresh. She spoke as if each word needed permission. Her ex-husband, Todd Kline, had skipped child support for eight months, then tracked her to the shelter and made sure she “understood the consequences” of asking again.

When Marcy finished, Anne closed the folder with the delicacy of someone handling dynamite. “I’ll get your support,” she said. Then her tone cooled. “And I’ll get something he doesn’t owe you—but he deserves.”

Anne found Kline at Rusty’s Garage, puffed up with beer and the kind of swagger cowards buy cheap. He didn’t recognize her at first. She let him stew in that confusion before she stepped closer, her shadow swallowing his.

“You Todd Kline?” she asked.

He smirked. “Who’s asking?”

“The woman who’s here to collect.”

She pinned him against the workbench before he could blink. Years of Krav Maga and a childhood spent dodging trouble gave her strength he couldn’t match. She leaned in until her voice was a whisper wrapped in barbed wire.

“You hit Marcy again, you hit her with words, fists, breath, or looks—and I swear you won’t need child support because you’ll be eating through a straw for the rest of your miserable life. Do you understand me?”

Kline’s bravado drained away like oil from a cracked pan. He nodded.

Anne twisted his wrist just enough to make the message unforgettable. “Good. Now you’re going to give me every cent in your wallet for Marcy. Consider it interest. Each Friday you will make a payment to her until  every cent you owe. On time. Starting Friday. And, you’ll keep making payments for the children until they’re 19.”

She left him trembling, a grown man suddenly aware of the shadows he’d never bothered to fear. 

Back in her office, Anne wrote one sentence in her case notes: Debt collected. Interest delivered.

Justice didn’t always roar. Sometimes it walked out of a dim garage wearing a trench coat and smelling faintly of gunpowder and resolve.
