The Mastiff with the Brass Warning

I didn’t waste a second. I let the shotgun drop through the opening and plunged after it, headfirst, as the front door crashed inward above me.

The ground slammed into my shoulder. I rolled clear of the splintered boards dangling from the crawlspace ceiling, then covered my mouth to choke back a cough.

Tear gas seeped down after me, stinging my eyes and throat. Upstairs, boots hammered through the kitchen, close enough that I felt each step in the dirt.

A radio crackled overhead. “First target secured. He’s breathing. Sedate him and get him ready to move.” The voice sounded flat and electronic.

Another operative asked about the local. His boots came down directly above the hole, and dust sifted onto my back.

“Search the rooms. He didn’t get out through the rear.”

I snatched up the shotgun and eased forward on my belly. The space beneath the trailer was so tight I had to drag myself through it inch by inch.

Damp earth soaked my sleeves. The air reeked of mildew and rotting wood, and cobwebs smeared across my face as I worked toward the back.

I fought the urge to wipe them away. Even the smallest movement seemed too loud with armed men searching above me.

Someone reported a hole in the floor. A powerful flashlight beam plunged through the opening, probing the black space only a few feet from my boots.

I pressed my cheek into the cold soil and went still. My heart thumped hard against my ribs while the light searched around me.

It slid one way, then the other. The beam passed close enough that I could see it glint across the dirt beside my legs.

“He’s beneath the trailer. Flush him out.”

I kicked forward before they could try. My shoulder struck the rear lattice, and the weather-beaten slats snapped apart with a crack.

I spilled through the gap into weeds at the back of Mark’s yard. I got upright and ran for the trees.

Muted rifle shots popped behind me. A round hit an oak near my head, bursting its bark into fragments that peppered my neck.

I dropped low and plunged into the brush, changing direction as I went. Years spent learning these woods helped me find a way through the briars.

I kept running until my lungs seemed ready to tear and the forest’s deep quiet swallowed the sounds of the men behind me.

At last I sagged against a broad pine, sucking air. Sweat and mud clung to my clothes, and my hands shook around the shotgun.

They’d taken Mark. They had the maps. But the dog was still with me.

I pushed off the tree and started the hard trek toward home. A dry creek bed gave me a sunken route where the banks hid my movement.

The light was fading fast behind the Appalachian ridges. Twilight pressed between the trees, making the woods feel narrower with every step.

Near my property line, a low mechanical drone reached me from above. I flattened myself against a muddy slope and looked through the canopy.

A black surveillance drone moved over the treetops, its red thermal beam sweeping across the ground below. The retrieval team was locking down the area.

I stayed beneath the bank until it had passed, then continued toward the steel barn. Twenty minutes of careful movement brought me to its rear door.

The doors were locked. I gave the side entrance our agreed signal: three quick taps, a pause, then one solid knock.

The deadbolt turned. Doc Evans pulled me inside and slammed the steel door behind me, securing it before I could catch my breath.

One battery lamp cast a small circle across the otherwise dark barn. Evans stared at me, relief widening his eyes.

“Elias! I heard the shots. I thought they’d got you.”

“They’ve got Mark,” I said, panting. I rested the shotgun against the bench and wiped the tear gas from my face with a grimy rag.

“The retrieval team is searching the woods,” I told him. “They’re closing in, and we don’t have much time.”

Then I saw the mastiff. He was out of the truck, circling the iron grate fixed into the barn’s concrete floor.

The heavy grate covered the old quarry’s ventilation shaft. The dog moved around it with purpose, nose lifting each time he passed over the bars.

He stopped and pressed his muzzle close to the iron, drawing in the air from the shaft below. His attention never wavered.

Evans shifted uneasily. “He’s been going around it for ten minutes,” he whispered. “It’s like he wants to go down.”

“I understand now,” I said. The pieces had finally come together, and the answer left a hard, cold feeling in my gut.

I crossed to the workbench and gripped its edge until my trembling hands steadied. “This is why they want the land, Doc. Mark showed me the plans.”

“Apex-Bio found a sealed cavern beneath this property,” I continued. “It’s full of toxic gases.” Evans frowned and adjusted his glasses.

“Toxic?”

I looked toward the dog. “They made him for that shaft. Asset 04 wasn’t meant to guard a boundary; they engineered him to survive what’s down there.”

His nose remained at the grate, breathing in the dark air. I believed Apex-Bio had built him to descend into the cavern and bring back whatever they had found there.
