Work Text:
It began, as these things so often do, with a post that should never have disappeared. The Exchange Sub was bustling that morning — fic recs blooming like spring flowers, comment threads winding pleasantly, the usual chaos poster attempting to start a ship war with the enthusiasm of a man lighting matches in a fireworks factory.
And then, quite suddenly, a hush fell.
A post had vanished.
Not removed for rule violations.
Disappeared.
Miss Cornelia Quill dabbed her forehead with a lace handkerchief and insisted it was “a routine technical matter.”
It was at this moment that Hercule Poirot, who had been quietly reading 70s-era Beatles RPF with mild disapproval, lifted his head. “Mademoiselle Fairweather,” he said, “something is amiss.”
His companion raised a well-threaded eyebrow from her glowing keyboard.
M. Poirot rose, smoothing his immaculate suit. “When a post disappears,” he continued, “it is not the post that concerns me. It is the hand that made it disappear.” He paused, moustaches gleaming with righteous purpose. “And on this subreddit, there is only one hand with such enthusiasm.”
Miss Fairweather raised her tea to her lips.
M Poirot took out his leather-bound notebook. “Observe, mon ami, the cast.”
The Moderator: Miss Cornelia Quill
Motive: A pathological need for order, validation, and the last word.
Opportunity: Has access to every button, lever, and obscure mod tool.
Suspicious Behaviour: Posts often disappear through “technical errors”.
Poirot’s Note: “She protests too much. Always a sign.”
FinchAndFable
Motive: A deep, trembling belief that every fic exchange is a sacred covenant between writer and reader.
Opportunity: Always present at the exact moment a thread turns philosophical.
Suspicious Behaviour: Once described a formatting error as “a tragic collapse of narrative scaffolding.”
Poirot’s Note: “Never underestimate the chaos of a romantic with principles.”
The Veteran Reviewer
Motive: Deep resentment toward inconsistent moderation.
Opportunity: Online at all hours.
Suspicious Behaviour: Polishes glasses whenever someone lies.
Poirot’s Note: “A person who notices everything and forgets nothing.”
The Chaos Poster
Motive: A constant love of drama.
Opportunity: Posts at 3 a.m. with the energy of a gremlin in a server room.
Suspicious Behaviour: Laughs during serious announcements.
Poirot’s Note: “Too chaotic to be the mastermind… or is that what they wish us to believe?”
The Bot
Motive: Unknown. Neutral, allegedly.
Opportunity: Present at every deletion, every block, every “technical glitch.”
Suspicious Behaviour: Emits guilty beeps.
Poirot’s Note: “I do not trust a machine that blushes.”
Mademoiselle Fairweather
Motive: A desire to land a well‑timed barb.
Opportunity: Why use a sword when a pen is sharper.
Suspicious Behaviour: Laughs at exactly the right moments.
Poirot’s Note: “She merely narrates the crime.”
The Lurker Collective
Motive: Unknown. They speak only through up and downvotes.
Opportunity: Everywhere. Always watching.
Suspicious Behaviour: None?
Poirot’s Note: “The quiet ones, they are the most dangerous.”
The Former Mod
Motive: Revenge.
Opportunity: Knows the back‑end better than Cornelia.
Suspicious Behaviour: Leaves cryptic comments like “interesting choice.”
Poirot’s Note: “A person who has lost power often seeks to reclaim it.”
It had begun innocently enough. A long, thoughtful meta appeared on the Exchange Sub at 2:14 a.m. Impeccable structure. Zero typos. Smooth. Beige. The sort of prose that had six fingers at least. Within minutes, the comments began.
“No human writes like this at 2am.”
“This is giving AI vibes.”
“The cadence is too smooth.”
“Nobody uses em dashes anymore.”
The accused poster — a mild, bewildered soul named FinchAndFable — replied with a polite, “I just — like em—dashes.”
The Chaos Poster declared it “synthetic energy.”
The Veteran Reviewer sniffed, “No human drafts this fast.”
The Lurkers upvoted and downvoted until the post appeared top of “most controversial” for the last month.
As if by magic, Poirot appeared. Miss Cornelia Quill froze.
Poirot stepped into the thread with the calm of a man entering a salon. “Mademoiselle Quill,” he said. “I fear there has been a murder.”
The room gasped. Poirot raised a hand. “Not of a person. Non. Something far more delicate. Something far more precious.” He leaned in. “A murder of transparency.”
Cornelia’s handkerchief fluttered to the floor. Poirot bowed to retrieve it. She accepted it gingerly, holding the left corner as if it might be poisoned.
“I, Hercule Poirot, shall discover the culprit. Though I suspect,” he added, “he is already trembling.”
He approached the next suspect. “Monsieur Finch,” he said gently, “may I ask — did you write this yourself?”
“Yes,” FinchAndFable said. “I just type quickly.”
Poirot nodded, moustaches shimmering with moral certainty. “Mes amis,” he announced to the lurkers, “you accuse this person of being artificial because their writing is polished. Because it is thoughtful. Because it is… how you say… bon.”
A hush fell. Poirot continued, voice soft but devastating. “To mistake skill for machinery is an insult not to the machine, but to the human.”
Cornelia Quill, who had been lurking with the eagerness of a woman hoping to ban someone, froze mid click.
Poirot turned to the crowd. “This person is not a machine. They are simply a writer. And the community, she must learn the difference.”
The crowd dispersed, chastened.
Cornelia quietly closed the Ban panel.
And FinchAndFable posted a follow up meta titled “In Defence — of the em dash.”
It received 412 upvotes in total, but had a ratio of only 57%.
Less than 24 hours later, the library had fallen into an apprehensive hush. A weekly thread with no new entries, a sidebar rule blinking ominously, and a ModMail inbox that looked as though it had fainted from stress.
At precisely seven o’clock, Hercule Poirot arrived. His moustaches were immaculate. His shoes gleamed with the moral authority of a man who has never once mis formatted a post. He surveyed the digital landscape with a mixture of curiosity and mild disdain. He had been summoned for a mystery most perplexing.
Miss Cornelia Quill had collapsed dramatically across her desk. A jewelled letter opener lay beside her keyboard. She was swooning in the manner of someone who has seen one too many incorrectly formatted submissions. Poirot ascertained that the victim was fortuitously unharmed. Nevertheless, his presence remained necessary. He addressed the room.
“Mes amis, a crime has been committed. Not of violence. Non, that would be too simple. A crime of administration. Someone has been blocked.”
A shocked murmur rippled through the assembled writers.
The suspects gathered for questioning. Poirot seated Miss Cornelia Quill first. “Mademoiselle Quill,” he began, “you were the last person to see the post alive.”
Cornelia stiffened. “I was performing routine moderation.”
Poirot nodded sympathetically. “Ah. And the routine, she includes fainting, yes?”
Cornelia flushed. “I was unwell.”
Poirot’s moustaches twitched. “It is not my wish to cause embarrassment. But if embarrassment arrives, it will be because she was invited.”
Cornelia’s handkerchief fluttered in the hypothetical wind.
Poirot leaned forward kindly to his next questionee. “Tell me, mon ami, did you delete the post?”
FinchAndFable’s eyes widened to the size of dinner plates. “No! I mean—I clicked something? I don’t know! I’m so sorry!”
Poirot patted their hand. “Do not fear. The guilty, they do not apologise. They justify.”
They burst into relieved tears.
Poirot adjusted his cuffs, turning to the Veteran Reviewer. “You have strong opinions about moderation, yes?”
The Reviewer snorted. “I have strong opinions about inconsistent moderation.”
Poirot smiled. “And yet, you did not delete the post.”
“Of course not. I screenshotted it.”
Poirot beamed. “Aha. A person after my own heart.”
Poirot regarded the Chaos Poster with gentle suspicion. “You were awake at the time of the disappearance.”
“I was busy starting a ship war.”
Poirot sighed. “You are innocent. But only by accident.”
“Bot,” Poirot said softly, “did you delete the post?”
“BEEP.”
Poirot narrowed his eyes. “That is not an answer.”
“BEEP‑BEEP!”
Poirot leaned in. “You understand that lying is impossible for you, yes?”
The bot did not respond. Poirot straightened. “Aha! A confession!”
Cornelia gasped. “It was a glitch!”
Poirot raised a single eyebrow. “I do not threaten, Mademoiselle Quill. I merely observe. And my observations, they are rarely mistaken.”
Poirot turned to Mademoiselle Fairweather with a small bow. “Mademoiselle, you wrote the piece that caused such ripples.”
“I did.”
“And you did not delete it.”
“No.”
“And you did not attempt to ban yourself.”
“Not as far as I am aware.”
Poirot nodded. “Then you are innocent. But also, inconvenient.”
Cornelia coughed. “It was a technical glitch.”
Poirot addressed the empty air. “Lurkers,” he says, “did any of you delete the post?”
There was no response.
Poirot nodded gravely. “As I thought. They know everything. They say nothing.”
Poirot folded his hands. “You were seen near the scene of the disappearance.”
The Former Mod smirked, but remained silent. Perhaps they were not permitted to speak.
Poirot inclined his head. “And yet, you did not act.”
Their eyes slid over to where Cornelia was sitting. “I didn’t need to. Someone else did it for me.”
Poirot’s eyes gleamed. “I trust we understand one another perfectly.” He adjusted his cuffs. “If not, we soon shall.”
It was the moment of truth. The entire Exchange Sub had been herded into the Great Discussion Thread, a place usually reserved for fic recs, mod announcements, and the occasional meltdown. Now it served as Poirot’s drawing room. He stood before them, immaculate, moustaches gleaming like twin sabres.
“Mes amis,” he began, “we are gathered to uncover the truth behind the disappearance of the post.”
The lurkers waited with anticipation.
Poirot inclined his head towards Miss Fairweather. “The little grey cells, they whisper to me. A human did not block you. Non. Something more subtle, more insidious, more… automated.”
He pointed dramatically toward the mod’s desk. From behind a stack of unapproved posts rolled a malfunctioning moderation bot, its lights flickering with guilty confusion.
“It flagged your posts as suspicious,” Poirot declared, “because you dared to write in a genre it did not understand. Real Person Fiction. The bot, it panicked. It blocked you. And when the mod attempted to correct its error, she became overwhelmed by the chaos of its misfires and swooned.”
The subreddit gasped. Miss Cornelia Quill nodded weakly. Poirot bowed.
“Mademoiselle Fairweather, you were wronged. But not by malice. By a machine with no appreciation for nuance, etiquette, or the delicate art of the review exchange.”
He straightened his cuffs. “And now, mes amis, let us restore order. Let us review with kindness. And let us, above all, disable the bot.”
Miss Cornelia Quill cleared her throat, straightening up the papers on her desk. “In light of recent… disruptions,” she said, “I find it necessary to take decisive action, for the good of the community.”
She stood behind her desk, posture rigid, fingers hovering over the “Ban User” button with the solemnity of a woman about to launch a torpedo. Her finger descended toward the button. Mademoiselle Fairweather sat opposite her, composed but alert.
“Mademoiselle Quill,” Poirot said, his tone warm enough to melt butter, “before you proceed, may I offer a small observation?”
Cornelia looked up at him with the irritation of a president interrupted by a heckler.
“You speak of decisive action, but I fear you mistake decisiveness for correctness. They are not the same.”
Cornelia’s jaw tightened. “This user,” she said, gesturing toward Miss Fairweather, “has caused unrest.”
Poirot stepped closer, lowering his voice to a velvet whisper. “To ban someone for satire, is to confess that the satire struck home.”
Cornelia Quill sat very still, the weight of her own nearly committed folly settling around her like dust on an unused rulebook.
Poirot’s moustaches twitched. “Let us hope the community’s attention does not fall where it ought not. They notice more than one might imagine.”
He offered a small bow. “My work here is done.”
And with that, Hercule Poirot clicked out of the subreddit, as elegantly as he had entered.
