Chapter 4 - The Concrete Tomb

Rain had begun to fall in cold, needle-sharp sheets, turning the backyard grass into slick mud. The clouds overhead swallowed the moonlight whole, leaving only the amber glow of the neighborhood streetlamps filtering through the trees.
I didn't run toward the street. Silas was faster, and his truck was likely blocking the driveway. Instead, I bolted directly toward the one place where the answers lay buried—the backyard shed.
I threw my shoulder against the wooden door. The broken latch gave way instantly, swinging inward with a low groan. The air inside the shed was thick with must, rot, and the unmistakable metallic odor of rust and fresh motor oil.
"Intake valve... intake valve..." I repeated Dad's written words frantically under my breath.
I whipped out my phone, turning on the flashlight. The beam swept across dusty shelves lined with ancient mason jars full of screws, dried-out paint cans, and broken weed trimmers. In the far corner sat an old industrial workbench, bolting a heavy vice grip to a slab of rotten plywood. Below it, the concrete foundation looked odd—it was uneven, raised four inches higher than the rest of the perimeter, with crude trowel marks etched into the gray surface.
Heavy boots slammed against the wet grass outside. Silas was ten yards away.
"You're making this worse on yourself, Emily!" his voice roared over the wind. "Your mama is going to tell the cops you broke down out of grief and ran off! Nobody finds bodies in the Trinity River when the floodgates open!"
Frantic, my flashlight caught a circular cast-iron plate beneath the workbench, hidden beneath a pile of moldy burlap sacks. It looked like an old industrial storm drain cover, secured with three large hex bolts. Two of them had already been loosened, recently stripped by fresh wrench marks. Silas had been preparing to seal it permanently.
Beside the bench lay a heavy pipe wrench. I grabbed it, dropping to my knees on the cold concrete. Using every shred of adrenaline, I jammed the wrench onto the remaining bolt and shoved downward. The rusted metal shrieked, then gave way with a violent snap.
I shoved the heavy iron plate aside.
A dark, rectangular concrete shaft plunged straight down into the earth, roughly four feet wide. An unbearable stench hit me—damp earth, sewage, and unwashed human misery. A rusted steel ladder was welded into the concrete wall.
From the black depths below, through the sound of the falling rain, came a sound that stopped the blood in my veins.
*Tap. Tap.*
A pause.
*Tap.*
Two quick knocks. One slow.

"Dad?" The whisper tore out of my throat, choked with disbelief.
Before an answer could come, a massive, calloused hand grabbed the back of my collar, yanking me viciously away from the opening.
