I write horror serials nobody reads.
Two hundred and thirteen paid subs at five bucks a month. My agent — when I had one — told me to switch to romantasy. My landlord texts me about the September rent on the seventeenth of every month.
Then one Tuesday a padded mailer shows up with no return address, sealed in black wax, and inside is a crime-scene photo from a theater on Canal Street.
The staging matches Chapter 13 of my serial. Down to the dropped camellia.
Zelle pings my lock screen ninety seconds later. Forty-two thousand dollars. The memo says: royalties — chapter 13.
After that, every time I post a chapter, somebody dies. The Seventh Night hits the Substack trending list. My follower count goes from quadruple digits to seven. Cypress House moves my launch up to Friday. The detective on the case starts pulling my browser history.
On launch night, a man in a white shirt and gold-frame glasses walks on stage and hands me a pen.
He smiles into the cameras. "Time to write the ending, M. Wren. The woman in this chapter is you."
I close my hand around the pen. The cap is cool brass, screw-off. My thumb finds something scratched on the inside lip.
It's the SOS I scratched into a library book the year I turned twelve.
I'm halfway through a gas-station burrito two days past its sell-by when the mailer comes.
Kraft padded envelope, no return address, the flap closed with a coin of black wax. The wax is pressed with a raven in profile, eye closed. Hand-stamped. Heavy.
I assume it's a reader stunt. The horror Substack scene runs hot on wax seals and unboxing videos. Somebody saw my chapter art and went to Etsy.
Then the photo slides out.
A woman in the center of the orchestra of the Orpheum Theater on Canal. Red wool coat. White opera gloves. A wilted white camellia on the floor at her feet. Row J, seat 14.
Chapter 13 of The Seventh Night. The Woman in the Red Coat at the Orpheum. Detail for detail.
My fork hits the counter.
The phone buzzes against the laminate.
Zelle. $42,000.00.
Memo: royalties — chapter 13.
I look at the memo for a long time. My stomach turns over twice.
I do not call the cops.
Not because I'm noble about it. Because Chapter 13 went up to a paid tier with two hundred and thirteen subscribers. It has seventeen reads. Three comments, and two of them are spam.
Nobody murders for a Substack horror serial that nobody reads. Nobody sends forty-two grand to a writer whose Wattpad bio still says aspiring.
I shove the photo back into the envelope and call Daphne.
Daphne Lascelle is my editor at Cypress House. She picks up on the third ring with traffic in the background — Magazine Street, midmorning — and listens for thirty seconds before her first sentence.
"Wren. This isn't a stunt, right? Because if you're seeding a viral arc for the launch, I need to know now so legal can paper it. We have the acquisition meeting in eleven days."
I'm shaking by the third word.
"Daph. I'm seventeen days late on rent. Where would I get forty-two thousand dollars to fake a homicide."
A pause. I hear her open her laptop. Keys clatter.
"Don't move. Don't post anything. Let me check the wire."
She hangs up.
Ten minutes. I sit at the counter and watch the burrito sweat through its foil.
She calls back. The traffic noise is gone — she's in her office now, door closed.
"It's real," she says. "NOPD has a body at the Orpheum since six this morning. Embargoed. No press. How the hell —"
She stops herself.
"Wren. You listen to me. You pull Chapter 14. You email me a takedown of the whole serial by tonight. We unpublish The Seventh Night. You stay off socials."
I'm about to say yes when my laptop chimes.
A new comment under Chapter 13. The handle is @nightwatch_rdr. The display name reads Nightwatch.
The comment is one line, then a second under it.
Don't stop posting.
If you do, I'll write it for you.
Daphne tells me to take a Lyft, not a streetcar. She is already in the Warehouse District conference room with the door shut and the slat blinds pulled when I get there.
Black blazer. Unlit cigarette between two fingers. She does not smoke; she has been holding the cigarette for an hour.
"You bring it."
I put the envelope on the table.
She pulls on a pair of nitrile gloves from the breakroom first-aid kit and turns the photo over twice. Her color leaves her face the way water leaves a draining sink.
"Wren. You're in something."
I make a sound that isn't a laugh. "An hour ago you wanted to know if I was running a publicity stunt."
She doesn't push back. She opens her laptop and turns it so I can see.
A screenshot from a closed NOPD-PIO Slack channel a friend of a friend forwarded her. Victim name: Dr. Margaux Ridley, forty-nine, clinical psychologist, Garden District practice. Lives alone. Found at the Orpheum at six a.m.
My head goes bright with a small pain behind my left eye, like somebody pushing a pin into the socket.
Daphne sees it. "You know her."
"No."
I say it too fast.
She puts the unlit cigarette down. Her voice tightens. "Wren. Then explain to me how you wrote her."
I don't.
Horror serializers write dead women. We do not, as a rule, owe anyone an explanation.
But the Ridley name is sitting in my eye socket like a splinter.
Because the red-coat woman at the Orpheum showed up in a dream three months ago. Same theater. Same seat. She kept turning back to me from row J and saying the same thing.
Don't look behind you.
Daphne spins the laptop and pulls up the Substack dashboard.
Yesterday Chapter 13 had seventeen reads.
This morning The Seventh Night is climbing the Substack horror trending column. New subscribers refresh as I watch — seventy, ninety, one twenty.
Comments under Chapter 13 are stacking faster than the page can load.
holy shit irl serial killer arc
M. Wren predicted it ???
keep posting i need ch 14
who dies next i'm taking bets
I look at the comments and I feel the burrito climb back into my throat.
Daphne is about to say something when the conference room door opens without a knock.
The man who walks in is tall. Charcoal raincoat over a navy suit, water still on the shoulders. Eyes the color of a winter river.
He sets a badge on the table. NOPD Major Crimes.
"Detective Renaud Ember. I need Miss Mosely to come with me."
Daphne stands. "Detective. She is an author who received a piece of evidence in the mail this morning. She is voluntarily —"
Ember does not look at Daphne. He drops a stack of printer paper on the conference table next to the envelope.
It is Chapter 13. Off my Substack. Printed clean.
One sentence in the second-to-last paragraph is circled in red Sharpie.
"That sentence," Ember says, "was in Dr. Ridley's coat pocket. Folded once."
He reads it out loud.
"The first member of the audience has taken her seat."
The conference room is so quiet I hear the air handler in the ceiling kick on.
Ember's eyes settle on mine.
"You edited that line forty minutes before you posted Chapter 13. Substack edit history shows the change came from a single login. Yours."
The interview room at Major Crimes is bright in the way that medical examiners' rooms are bright. Nothing in it has shadow.
Ember sits across from me. His fingers tap once on the table, then stop.
"What was your relationship with Margaux Ridley."
"There wasn't one."
"She called your number three days before she died."
I look up. "That's not possible."
He slides his phone across the table. Call log. Unknown number. Inbound. Thirteen seconds.
Wednesday night. I remember.
I picked up and there was only breathing. I told whoever it was to lose my number and I hung up.
"She was asking for help," Ember says. "Thirteen seconds is what she had."
The room contracts.
"I didn't know."
He leans in. Voice down.
"And the forty-two thousand?"
I close my eyes for a second.
"Somebody sent it. I haven't touched it."
"You didn't call us."
"I was scared."
"Scared," he says. "Or were you keeping it."
That gets me on my feet.
"I'm broke. That doesn't mean I'll cash a dead woman's money."
The patrol officer outside the door cracks it open. Ember waves him off without looking.
"Sit down, Miss Mosely."
My chest is working. I sit down.
He slides a second photograph across. The image has been cropped and color-corrected; it isn't bloody. It is somehow worse for being clean.
A close-up of Dr. Ridley's left wrist, palm up. An old scar runs across the underside, thin and white.
"Shape of a W," Ember says.
The pin in my eye socket twists.
A flash, not visual exactly — a smell. Smoke and something chemical under it, the way nail polish remover smells if you spilled the bottle.
A child crying in the dark.
A second child's fingers in my palm, dragging.
W.
I press both hands to my temples.
Ember notices. "You remember something."
"No."
I hear my own voice come out wrong. Dry. Older than it is.
The door opens fast. A young officer leans in with a tablet, the screen still lit.
"Detective. We have another one."
He hands the tablet across without coming farther in.
A new Substack comment. @nightwatch_rdr.
Chapter 2 has been paid for.
My phone is in an evidence sleeve on Ember's side of the table. It lights up through the plastic.
Zelle. $67,500.00.
Memo: royalties — chapter 14.
