At first, I thought it was the boy.
His shuddering breath, his uneven steps. But then I realized: his feet weren't touching the ground. I was half-dragging him now, his legs trembling too much to carry him.
The sound came anyway.
A footstep.
Slow. Deliberate. Echoing just behind us.
I froze. My skin went cold, the air ripped from my lungs.
The woman didn't turn. She only lifted her hand, palm sharp in the air—stillness. Her head tilted, listening.
The boy whimpered against me. My hand clamped hard over his mouth. I could feel his pulse racing against my palm, hammering like it might burst through his skin.
The step came again.
Closer.
I could feel the weight of it behind me, pressing at the base of my skull, crawling along my spine. Each second stretched impossibly long, and my muscles locked in place.
The woman moved first. She didn't run. She slipped sideways into the narrowest passage, pulling us with her. The walls pressed tight against my shoulders, stone scraping my skin as we squeezed into the dark.
The step followed.
One. Then another. Slow. Measured.
It wasn't rushing us. It didn't need to.
I tried to look back. I shouldn't have. I wish I hadn't.
Something shifted at the far end of the tunnel—not a shape, not really, but a distortion. Wrong in a way that made the air itself feel wrong, bending and folding like it had weight.
The boy felt it too. His muffled sobs tore into my hand.
We moved again, deeper, the woman leading, her weapon angled low. She didn't look back either. She didn't have to. She knew what followed.
The tunnel forked. She chose left without hesitation. The scrape of her rebar against the wall marked the turn, but the sound felt too loud, too obvious.
The footstep came again, right behind us.
Not left. Not right.
Right behind.
I could feel it breathing now. Not on my skin, but in my head. Each inhale sank into my bones, colder than the stone around us. It weighed on my chest, rattled in my skull, and made my teeth ache.
We ran.
Not fast. Not wild. We couldn't afford wild. But every step felt like moving through water, every breath stolen from me.
The boy stumbled and nearly fell. I caught him, hauled him upright, but the sound of his stumble—
The thing answered.
Not with a growl. Not with a roar.
A laugh.
Soft. Wet. Broken.
The woman spun, slamming her rebar against the wall. Sparks jumped in the dark. "Keep moving!" she hissed, her voice sharp, ragged, slicing through the heavy air.
The laugh grew, stretching thin, splitting into many voices at once. It bounced off the walls, curling back around corners that didn't exist. The tunnel warped with it, like it wasn't just a place, but a living thing reacting to us.
The boy broke. He screamed into my hand, a raw, ragged sound that burned my ears.
And that was all it needed.
The shadow surged forward.
