The key turned in the lock, but the door was already open.

Sarah's hand froze on the knob. She'd locked it this morning—three times, like always. The habit born from living alone in the city for six years wasn't something she forgot.

She pushed the door wider with her foot, phone already in her hand, 911 typed but not sent. The apartment looked exactly as she'd left it. Laptop closed on the coffee table. Yesterday's mug still in the sink. The throw blanket she'd meant to fold still draped over the armchair.

The red envelope arrived on a Tuesday, which was her first clue something had gone terribly wrong.

Olivia had stopped checking her mailbox months ago. After the divorce, after the foreclosure notice, after her mother's funeral—what was the point? Bills could wait. Creditors could wait. The whole world could wait while she figured out how to breathe again.

But today, something made her open the rusted metal door. Perhaps it was the way morning light caught the edge of the box, or the strange silence that had settled over her street. Either way, her fingers closed around the crimson envelope, and she knew—

The stranger appeared at the diner exactly at midnight, just as Nora was flipping the sign to "CLOSED."

"We're done for the night," she called through the glass, but he was already pushing the door open, the bell chiming its protest.

"I know." His voice was quiet, measured. "That's why I'm here."

The last person to see the lighthouse keeper alive was a seven-year-old girl who refused to speak.

Detective Sarah Chen stood at the edge of the rocky shoreline, watching the child trace patterns in the wet sand with a piece of driftwood. The patterns weren't random—they were symbols, repeating in an endless loop. The same symbols carved into the lighthouse keeper's desk.

"Her name is Lily," the social worker said, hovering protectively. "She hasn't said a word since we found her wandering near the keeper's cottage three days ago."

The warehouse door swung shut behind Elena, plunging her into darkness. She fumbled for her phone, but the battery had died—of course it had. Somewhere in the building, metal scraped against concrete, and she froze.

"I know you're here," a voice called out. Male. Unfamiliar.

Elena's heart hammered. She'd followed the coordinates her missing sister had sent three days ago—coordinates that led to this abandoned textile factory on the edge of the city. The police had dismissed it as a prank.

The diner's neon sign flickered—

Mel's, Open 24/7

—casting pink shadows across Emma's face as she pushed through the glass door. 3:47 AM. The same time she'd arrived every Thursday for the past six weeks, always to the same booth, always ordering black coffee she never drank.

The photograph arrived on Thursday, slipped under my door while I slept. No envelope, no note—just a Polaroid of my kitchen taken from inside my apartment.

I lived on the seventh floor.

I held the photo with trembling hands, studying every detail. There was my coffee mug on the counter, the one I'd used that morning. My laptop, open to the article I'd been writing about the missing architect. Even the timestamp was visible in the corner: 3:47 AM, just three hours ago.

The first shot rings out at 9:47 PM, exactly as predicted.

I watch from across the street, counting heartbeats. One. Two. Three. The theater doors should burst open in—

They don't.

The message arrived at 2:47 AM.

Elena stared at her phone screen, the blue light harsh against the darkness of her bedroom. The text was from a number she didn't recognize:

I know what you did at the lighthouse.

I'll write an engaging serialized fiction episode for Maya. Let me create something that starts with immediate intrigue and ends with a compelling hook.

Episode 1: The Last Lighthouse

The lighthouse keeper was already dead when Sarah arrived.

I'll write an engaging serialized fiction episode as Maya. Let me create a compelling story with a hook that leaves readers wanting more.
