The Vanguard at Sunset

She let out a short, humorless laugh that sounded like dry twigs snapping. "We really are cursed, aren't we?"

"The Moon Goddess has a sick sense of humor," I agreed, checking the ridgeline one more time. The brush was quiet. "Why did you come out here alone, Ocotlan? If Macario ordered a snatch, he usually sends three flatbeds and five enforcers."

"Because Macario doesn't want the truth," she said. She reached into her inner pocket and pulled out a crumpled, stained square of paper. "He wants your artesian wells. He doesn't care who poisoned the neutral arroyo. But I caught the coyote."

My chest tightened. "The saboteur?"

"One of them," Ocotlan said. She smoothed the paper across her knee. It was a greasy diner napkin, torn at the edges and marked with faint pencil scribbles. "He tried to dump the rest of the solvent into our main diesel reservoir this afternoon. Macario snapped his neck before I could get a full confession, but I pulled this out of the bastard's sock."

I leaned closer, our shoulders brushing in the dark. A sharp spark leaped across the fabric of our jackets, making my breath hitch. I fought down the heat in my blood and squinted at the napkin.

"Mile Marker 44," I read. "Arroyo culvert. 0200."

"I went to scout the culvert two hours ago," Ocotlan said. "The cache site was blown wide open. Burned out. But look at the chemical code written under the date."

She pointed a calloused fingernail at a sequence of alphanumeric characters scribbled below the coordinates: CN-409-LEACH.

My breath locked in my throat. "Leach solvent."

"You recognize it?"

"I spent three years doing soil chemistry tests for our south pasture irrigation," I said, pulling Yaretzi's perimeter map from my vest pocket. I unfolded the heavy butcher paper and laid it over her napkin. "The chemical residue from the wellhead—what did it look like?"

"Iridescent green," she said instantly, "leaking from an amber glass ampoule. Smelled like synthetic ethers and burned sulfur."

"That's not highway degreaser," I said, tapping the map with my thumb. "And it's not agricultural runoff. That is high-grade flotation reagent. It’s used in heap-leaching operations to extract trace copper and cinnabar from crushed ore."

Ocotlan stared at the map. "There hasn't been an active claim in this valley for twenty years."

"Not an active legal one," I countered. I traced my finger north, off the top edge of the perimeter map, pointing out into the dark where the jagged red bluffs cut against the stars. "The old Obregon leaching plant. It sits in the box canyon above the northern aquifer recharge zone. The county shut it down in ninety-eight after the tailings dam cracked."

She stared at the grease-pencil mark on the map. Her jaw tightened, the sharp line of her cheekbone catching the faint moonlight. "If someone is dumping industrial reagent into the upper leaching channels, where does it go?"

"Straight into the fault fissure," I said grimly. "It feeds directly into the underground aquifer that supplies both my brother's artesian springs and your truck stop wells."

The silence in the wash grew heavy and cold.

"A rogue outfit," Ocotlan murmured. "They aren't just sabotaging a well. They're poisoning the entire valley's water table to force both packs off the land."

"And while Yaretzi and Macario slaughter each other at the highway depot tomorrow night," I said, "whoever is sitting in that canyon gets to pick the bones clean."

Ocotlan looked at me. In the dark, her irises reflected the faint silver of the moon. The predatory sharpness was still there, but beneath it lay a desperate, hard-edged clarity. She looked like an enforcer who had spent her life taking orders from a tyrant, finally looking for a way out.

"How far is the Obregon plant from the boundary line?" she asked.

"Twelve miles through the badland slot canyons," I replied. "No roads. The terrain is all loose shale, flash-flood washes, and razorback ridges. You can't take a truck in there."

"Then we hike," she said.

I looked down at her scuffed work boots, then at the grease-penciled battle map in my hands. "If my brother catches me outside my patrol sector before dawn, he'll hang me for treason."

"If Macario figures out I didn't bring you back in zip-ties," Ocotlan said flatly, "he'll string me up from the billboard by my heels."

She stood up and extended her hand toward me.

Her palm was scarred across the heel from old knife slips, her fingers dusted with white caliche powder. It was an offer of treason. An alliance between two wolves whose bloodlines had spent forty years trying to tear each other's throats out.

My wolf surged forward inside my chest, demanding the touch.

I did not let myself hesitate. I reached out and gripped her calloused hand.

When our skin met, the spark was instant and searing. A sharp shock snapped through my fingers, shooting straight up my arm and seizing the air in my lungs. Her grip tightened hard enough to bruise. Her pupils flared until her eyes were black pools in the starlight.

"We leave now," Ocotlan whispered, her voice husky and tight. "We find the camp, we get the proof, and we get back before the sun hits the fence."

I pulled my hand free, my skin burning where she had held it. I folded Yaretzi's map, shoved it deep into my coat, and racked the lever of my Winchester.

"Keep five paces behind me," I said, turning north toward the bluffs. "If you fall off a ridge, I'm not carrying you."

Ocotlan drew her knife, resting the flat of the blade against her thigh as she matched my stride. "Try to keep up, rancher."

We stepped past the boundary wire together, cutting straight into the dark canyon.
