Ellen was about to climb the staircase, ready to go up to her room, when a sudden loud noise startled her
She froze, her hand still gripping the bannister. The noise had come from behind the stairs. Frowning, she glanced over her shoulder, noticing for the first time that there was a door slightly ajar, just beneath the staircase. Curiosity piqued, Ellen let go of the bannister and slowly walked toward it.
"I didn't know there was a room here," she mumbled to herself, reaching for the doorknob and pushing the door open fully.
The door creaked as it swung inward, revealing a narrow set of stairs leading down into a dimly lit space. Ellen hesitated for a moment, wondering if she should check it out. She didn't recall ever stepping foot inside this part of the house. But the noise had been loud, and she couldn't shake the feeling that something was down there.
