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—she knew—that opening it would change everything.
No return address. No postage. Just her name in elegant script that looked almost alive.
Inside, a single card with seven words:
They found what you buried. Run now.
Olivia's breath caught. Her hands trembled, and the card slipped through her fingers, fluttering to the cracked pavement like a wounded bird. She hadn't buried anything. Had she?
The memory hit her like cold water—three years ago, the camping trip with David before everything fell apart. The midnight argument. The thing he'd shown her in that box. The hole they'd dug together beneath the oak tree, swearing never to speak of it again.
Oh God.
A black sedan turned onto her street, moving too slowly to be innocent.
Olivia ran.
She didn't grab her purse. Didn't lock her door. Just ran, her slippers slapping against concrete, her heart hammering against her ribs like a prisoner demanding release. Behind her, car doors opened—two quick thuds that sounded like a countdown.
One block. Two. Her lungs burned. The old playground appeared ahead, overgrown with weeds and forgotten promises. She'd played here as a child, knew every rusted swing and broken slide. Knew the gap in the fence that led to the creek.
She squeezed through, hearing fabric tear, feeling metal scrape skin. Behind her: footsteps. Closer now.
The creek bed was dry, littered with shopping carts and secrets. Olivia scrambled down the embankment, her mind racing faster than her feet. What had been in that box? David had made her promise not to look inside, and she'd kept that promise.
Until now, she'd almost convinced herself it was a dream.
A voice called out from above—deep, patient, terrifying in its calmness. "Ms. Chen. We just want to talk."
Liars always did.
Olivia pressed herself against the concrete drainage pipe, holding her breath as shadows moved overhead. Her phone was back at the house. Her car keys too. Everything she needed to disappear was exactly where she couldn't reach it.
But then she felt it—the raised edge beneath her fingers. Metal. A handle.
Impossible. This pipe had been sealed for years, ever since the flood of '09. She'd walked past it a thousand times, never seeing anything but solid concrete.
Yet here it was: a door that shouldn't exist, hidden in plain sight.
The footsteps grew closer. She heard radios crackling, voices coordinating.
Olivia gripped the handle and pulled.
The door opened silently, revealing darkness that felt alive. Somewhere deep inside, water dripped in a rhythm that sounded almost like speech. Almost like a warning.
"Check the creek bed!"
She had three seconds to decide: face whatever waited in the dark, or face the men who knew about the box.
Olivia chose darkness.
The door closed behind her with a soft click, and absolute blackness swallowed her whole. Her eyes fought to adjust, finding nothing but void. Then—far ahead—a pinprick of light. Not sunlight. Something else. Something blue and pulsing like a heartbeat.
She took one step forward.
Then another.
The light grew brighter, and she realized with creeping horror that it wasn't getting closer.
It was getting bigger.
