Chapter 4 - The Blueprint

The frantic scratching from inside the wall abruptly ceased, leaving behind a heavy, suffocating stillness that made the air in the empty bedroom feel impossibly thin. Buster continued to whine softly, his paws pressing desperately against the baseboard as if trying to tear through the lath and plaster. I pulled Sarah back toward the doorway, my hand steadying her as she struggled to catch her breath.
"We need to check the master suite," I said, my voice dropping to a low, urgent murmur. "Whatever was under these floorboards is moving toward our side of the house."
"That doesn't make any sense, Mark," Sarah replied, her voice shaking as she stepped back into the hallway, casting nervous glances into the dark corners of the upper landing. "The master bedroom is on the opposite side of the chimney stack. There's no crawlspace connecting these walls. The architect's blueprints clearly showed solid masonry between the west and east wings."
"Blueprints can be wrong, or altered, or outdated," I argued, flicking the smartphone flashlight ahead of us as we hurried down the carpeted corridor toward our bedroom. "Think about how cheap this house was when we bought it. The estate agent practically begged us to take it off their hands. Houses don't go for fifty percent below market value just because the kitchen needs updating."
Sarah stopped dead in her tracks just outside our bedroom door, her face turning pale in the dim light. "What are you implying? That the previous owners knew something? That's insane. The family who lived here before us passed away in a car crash out of state. It's a tragedy, not a conspiracy."
"People die in car crashes every day, Sarah. But houses don't usually come with inexplicable cold spots and things moving through the walls at three in the morning," I retorted, stepping past her to enter our room.
The master bedroom was quiet, bathed in the cool silver glow of the moon. Everything was exactly where we had left it before the noise woke us—the unmade king-sized bed, the laundry basket in the corner, the heavy oak dresser against the shared wall. I walked straight toward the dresser, setting the smartphone down on the surface to illuminate the area while I grabbed the heavy wooden piece by its handles.
"Help me move this," I ordered, bracing my legs against the floorboards.
"Mark, you're losing your mind," she protested, though she stepped forward and grabbed the other side.
With a straining grunt, we shoved the massive oak dresser several feet to the left, scraping the legs across the carpet. As the heavy furniture cleared the wall, both of us froze.
Tucked into the corner where the baseboard met the drywall was a small, crudely cut square of wood, measuring roughly ten by ten inches. It had been carefully sawed out and reinserted, held in place by modern drywall screws that clearly didn't match the 1920s construction of the rest of the house.

I knelt down, grabbed one of the screws with my fingernails, and twisted it. It came out with startling ease, as if it had been unscrewed and replaced just hours before.
