Chapter 11

The absolute darkness swallowed the hallway instantly, leaving only the sickly green luminescence pulsing from the grinning aperture in the white door. Mark reached out blindly in the gloom, his hand brushing against David’s trembling shoulder.
"Dave? Stay close to me," Mark whispered, his voice steady despite the sheer terror gripping his chest.
"I can't see the exit," David whispered back, his voice strained and panicked. "The front door... it locked itself. The deadbolt won't turn."
"Forget the front door," Mark said, his eyes fixed on the pulsing green light ahead. "The house isn't letting us leave through the foyer anymore. It wants us to go deeper."
As if responding to his words, the grinning mouth on the white door snapped shut with a resounding crack. The peeling hair-like fibers retracted, and the door slowly swung inward on its own hinges, revealing a steep, narrow wooden staircase leading downward into the pitch-black abyss.
A wave of air rushed up the stairs—not cold this time, but stiflingly hot, smelling of damp earth, old photographs, and the distinct, metallic tang of fresh blood.
"We are not going down there," David said, backing away until his spine hit the opposite wall. "We are going to take that crowbar, smash the living room windows, and climb out."
"Look behind you, Dave," Mark replied quietly.
David turned around in the dark. In the faint, eerie glow of the doorway, they could see the living room entrance. But the hallway hadn't just gotten darker; it had grown longer. The living room, which had been only ten feet away just moments ago, now looked miles down the corridor, a tiny square of distant light that was rapidly shrinking as the walls began to slide inward.
"The house is contracting," Mark realized, the horror dawning on him with crystal clarity. "If we don't go down the stairs, the walls are going to crush us right here in the hallway."
David swallowed hard, his breathing ragged. He looked at the shrinking sliver of light in the distance, then down the steep, terrifying wooden staircase leading into the unknown depths of the hidden basement.
"Buster!" David suddenly remembered, his voice rising in panic. "Where's the dog? Buster was right by the sofa!"
Mark felt his heart skip a beat. He pulled his smartphone from his pocket, pressing the power button desperately. The screen flickered to life for a split second, casting a pale, ghostly light over the floorboards.
There was no sign of Buster. The golden retriever was completely gone, leaving only a small, neat pile of his black collar resting on the floor right at the top of the basement stairs.
Without a single word, Mark stepped past his brother and walked straight toward the open cellar stairs, picking up the black collar in his trembling hand.

"Mark, wait!" David cried out, scrambling after him. "You can't just go down there blindly!"
"Buster went first," Mark said over his shoulder, his voice cold and resolute as he placed his foot on the first creaking wooden step of the staircase. "And I'm going to find him, even if I have to tear every wall in this cursed house down with my bare hands."
