The Mastiff with the Brass Warning

I brought the collar out from inside my jacket. Its brass plate, stamped ASSET 04, had grown hot against my hand, giving off a faint, rhythmic warmth. Along its rim, a hairline gap betrayed something hidden inside. This wasn’t ordinary identification. A locator beacon had been sealed beneath the metal, built to withstand more than a knock or a fall.

“Well, hell,” I muttered. I lowered the window, drew my arm back, and flung the collar into the trees with all the strength I could manage. It disappeared among the brambles and poison oak.

If that beacon was what they followed, they’d waste time searching the wrong stretch of forest. It wasn’t much of a plan, but it was the only one I had.

“What’d you find?” Evans shouted from behind me, raising his voice over the truck’s engine.

“A tracker!” I yelled back. “It’s in the woods now. We’re heading to my barn. Nobody knows this road leads there.”

We reached my place about ten minutes later. The truck jolted off the track and onto the rough drive as we emerged from the trees. I kept my eyes on the way ahead, thinking about the dog in the bed and the people hunting him.

I drove the truck into the barn and shut off the engine. The sudden quiet made the pounding of my heart seem louder. For a moment I stayed behind the wheel, gripping it while the last of our escape rattled around in my head.

Then I climbed out and went to see how the mastiff was doing. Evans was beside him in the truck bed, fixed on the dog with an expression I couldn’t read.

“Doc?” I asked. “Is he still breathing?” The thought that we might have gotten him this far only to lose him tightened my chest.

Evans glanced up at me. “Elias, take a look.” He sounded so subdued that I stopped where I was.

I climbed into the bed and followed his gaze to the mastiff’s shoulder. The rattlesnake had bitten him less than an hour earlier. At the clinic, the flesh around the punctures had been swollen and dark, bruised-looking and stretched tight.

Now that swelling had disappeared. I leaned closer, trying to make sense of what I saw. The skin around the bite looked pale pink instead of purple, and the damaged area appeared to be healing.

I stared at it, expecting to find the injury hidden by shadow or by some trick of the light. Nothing changed. The tissue that had looked so badly hurt at the clinic had recovered with a speed I couldn’t explain.

“That can’t be right,” I said. My hand hovered near the dog’s shoulder, uncertain whether I should touch him. “The antivenin can stop the venom from spreading. It can’t undo all that damage this fast.”

“I understand,” Evans replied. His fingers shook a little as he took a penlight from his pocket. He leaned in and carefully raised one of the mastiff’s eyelids.

At the clinic, the dog’s eyes had looked dull and sedated. Now the pupil was wide, and light caught the iris in a vivid amber gleam, bright as polished metal. It was unlike any reflection I’d seen in an animal’s eye.

A rumble sounded from the dog, low enough to vibrate through the bed of the truck. Evans jerked back in surprise, and his penlight slipped from his hand.

The mastiff lifted his head. He didn’t seem confused or groggy. He moved with a steady purpose, and the truck shifted beneath his weight.

As he pulled the IV free, I caught myself holding my breath. The dog showed no sign of distress. He simply turned to face me.

We were close enough that I could see every detail of his scarred muzzle. My body went rigid. I remembered how easily he had knocked Clara over, and the heavy post Mark had broken across his ribs.

But the mastiff didn’t snap at me or bare his teeth. He only watched, his gaze seeming to measure me. There was something unnervingly alert in it, something that made the hair rise on my arms.

Then he leaned forward and rested his nose against my chest. His touch was gentle, right above my racing heart. I stayed perfectly still, not knowing whether to be afraid or grateful.

He breathed out softly and settled his head on his front paws. His attention shifted to the barn doors, where it remained fixed.

From farther along the truck bed, Evans spoke in a hushed voice. “He knows they’re after him.” His face had gone pale.

I tried to swallow, but my mouth was dry. “Doc, what are we dealing with?”

Evans took a slow breath. “I drew a blood sample before we left the clinic. It’s in my bag. I need my field microscope.”

I looked from the sample bag to the mastiff, who lay watching the doors as if he could hear the people coming for him. Evans reached for his equipment, preparing to examine the dog’s blood and find out what the animal really was.
