Chapter 2 - The Echoes in the Drywall

The sound of those footsteps scraping against the interior studs of the house sent a cold spike of adrenaline straight down my spine. They weren't heavy footsteps; they were light, deliberate, and calculated, dragging something heavy along the floorboards hidden behind the plasterboard.
"Dad? What's that noise?" Emma whimpered from her bed, her small hands gripping the duvet so tightly her knuckles turned white.
I forced myself to snap out of my paralysis, tearing my gaze away from the gap behind the headboard. I stepped back, scooped Emma up into my arms, and backed out of the bedroom into the hallway.
"Everything's fine, sweetheart," I lied, my voice shaking despite my best efforts to keep it steady. "Just house settling noises. Old houses do weird things at night."
I carried her down to the living room, flicking on every light switch I could reach along the way. I sat her on the sofa, handed her my phone with a children's cartoon playing on low volume, and grabbed a heavy steel-handled wrench from my toolbox in the garage.
My mind raced. How could anyone be inside the walls? We lived in a detached suburban home that I had bought five years ago. I knew every square foot of the structure. Or so I thought.
I crept back up the stairs, heart pounding against my ribs like a trapped bird. The upstairs hallway was dead silent. I walked slowly toward Emma’s room, holding the wrench raised and ready.
I peered inside. The room was empty, save for the hum of the baby monitor. I approached the bed and knelt down.
The steel cable was still there, taut and unmoving. I took a deep breath, wrapped a thick towel around my hand to protect it from any sharp edges, and gripped the cable. With a firm, decisive pull, I hauled it toward me.
A sickening grinding noise echoed from inside the wall, like rusted gears being forced into motion. Suddenly, a section of the plasterboard near the baseboard groaned, cracked, and splintered outward.
A small, grimy hand shot through the jagged opening, fingers clawing frantically at the carpet.
I leaped backward, stumbling over a pile of stray toys, my breath catching in my throat. The hand withdrew instantly back into the darkness, followed by a sharp, raspy intake of breath from within the wall cavity.
"Who's in there?" I demanded, raising the wrench. "Show yourself right now! I've called the police!" (Even though my phone was downstairs and I hadn't called anyone yet).

Silence answered me. No movement. No footsteps. Just the faint smell of dust, old damp wood, and something metallic lingering in the air.
I didn't wait around to see what else might emerge. I backed out of the room, slammed the door shut, wedged a heavy wooden chair underneath the doorknob, and ran downstairs to grab my phone and dial 911.
