Chapter 7 - The Cavern of Echoes

We plunged into the absolute darkness of the mine tunnel, the sudden silence of the cavern standing in stark contrast to the howling storm outside. I switched on my flashlight, the beam sweeping over the damp, rough-hewn stone walls.
"We're safe here," I gasped, setting Lucy down on a dry patch of dirt.
Elena collapsed against the cavern wall, sliding down to the floor, pulling the twins into her lap. She was hyperventilating, the blood from her shoulder wound mixing with the mud on her shirt.
I took off my flannel shirt and tore it into strips, kneeling beside her to bind the wound tightly.
"You saved us," she whispered, her teeth chattering. "Just like she did."
I tied the knot off, my hands stained with her blood. "Sarah was the brave one. I'm just finishing what she started."
Elena looked around the dark, oppressive cavern. "How do we get out of here? They'll track us to the entrance eventually."
"This mine is a labyrinth," I explained, pulling up a mental map I had memorized from local history books years ago. "There's a secondary ventilation shaft about a mile deep. It leads out to the other side of the mountain, directly onto State Highway 44. That's outside of Miller's county jurisdiction. If we can flag down a State Trooper, we can hand over the SD card."
"Mommy, I'm scared," Lily whimpered, burying her face in Elena's neck.
"I know, baby," Elena soothed, rocking her gently. "David is going to get us out. Sarah promised us."
Hearing Sarah's name from the child's lips brought a fresh wave of agony, but I forced it down. "We need to keep moving. The deeper we go, the harder it will be for the dogs to track us."
We ventured deeper into the earth. The air grew stale and heavy with the smell of sulfur and damp rock. We navigated narrow passageways and crossed rotted wooden planks over deep, unseen chasms, the flashlight beam our only lifeline in the crushing dark.
For an hour, we moved in silence, the adrenaline slowly wearing off, replaced by a bone-deep exhaustion.
Suddenly, the unmistakable sound of loose rocks clattering echoed off the cavern walls behind us.
I stopped dead in my tracks, turning off the flashlight. We were plunged into absolute blackness.
"He's in here," I whispered, pulling the shotgun from my back.

A distant, echoing voice drifted down the tunnel. "Vance! There's only one way out of this mine! You're trapped like a rat!"
It was Miller. He had followed us in.
