CHAPTER 3: THE DECOY TRIGGER

The heavy match-grade primer ignited with a dull, subterranean thud that hammered straight through Elena’s collarbone.

A high-pressure jet of gray smoke spat from the side vents of the muzzle brake, stirring the dead gravel around her boots. Across the white-hot chasm of the basin, twelve hundred meters out, the lead target on the limestone shelf flattened. The man didn’t drop with the sudden, asymmetric collapse of a body striking iron; he simply rolled backward into a shallow depression, his olive-drab transceiver tumbling after him down the scree.

“Hit,” Miller growled, his hand already clamped around the handle of the canvas radio transit case. “But it’s soft. He was diving before the copper reached him. He knew the shot was breaking.”

Elena didn’t waste time looking for a blood trail through the thermal distortion. She rose into a low, dynamic crouch, her spine curving against the weight of the bolt-action system as she slung it over her shoulder. The heat coming off the bare rock was heavy enough to taste—dry, bitter lime that coated the back of her throat like chalk.

“We’ve got forty seconds before they map the flash,” she said, her fingers finding the nylon straps of her chest rig. “Move.”

They didn’t run. Running on the loose shale of the upper rim meant leaving deep, bright white scars in the sun-bleached limestone that a low-altitude reconnaissance drone could spot from five thousand feet. They slid down the reverse slope, keeping their hips low, their boots biting into the crumbling, rusty crust of the mountain. Every step sent a small cascade of dry dirt and ancient shell fragments down the draw behind them.

Before they cleared the secondary shelf, the sound hit them. It wasn’t the distant, crackling rattle of small-arms fire they had been trained to expect from an ambush. It was a rhythmic, heavy thumping that vibrated through the soles of their boots—a heavy twelve-point-seven-millimeter anti-material gun, buried somewhere deep in the low brush near the left ridge’s base.

“That’s not an intercept squad,” Miller said, pausing behind a jagged pillar of ironstone. He pulled his compact thermal monocular from his pocket, the rubber eyepiece clicking against his protective glasses with a faint, metallic scrape. “Elena. Look at the road. They aren’t tracking the convoy.”

She leaned against the rough, flaking stone, ignoring the sharp heat of the rock through her shirt. Taking the monocular from his hand, she brought it to her eye.

The digital screen rendered the basin in shades of lime green and blinding white. On the left ridge, three figures were moving toward the position where her target had dropped. They weren’t taking cover. They were walking upright, their silhouettes completely exposed to the valley below. Through the thermal sensor, their weapons didn’t show the white-hot signature of functional iron; the barrels remained cold, dark bars against the radiant heat of the limestone.

“The guns are scrap,” she said, her thumb adjusting the gain on the display. “They’re carrying hollowed-out frames. No bolt groups, no magazines. It’s a stage set.”

“They wanted the signature from our ridge,” Miller muttered. His face had gone the color of old paper under the grease and dust. He reached down, pulling a loose strip of rusted steel wire from the broken latch of the radio case and wrapping it around his palm until the skin went white. “If our station is logged as firing on an unarmed group during a ceasefire window, the regional command gets to claim a rogue element violation. They shut down the sector networks legally. They lock out our families’ security vouchers before the ink on our reports is even dry.”

“Look at the lead vehicle,” Elena interrupted, handing the optic back.

The six-wheeled transport had finally reached the sharp hairpin turn at the bottom of the grade. The driver hadn’t slowed down. The front tires caught the loose gravel at the edge of the asphalt, throwing up a massive fan of yellow stones that hammered against the rusted guardrail. The truck lurched, its heavy rear suspension bottoming out with a mechanical shriek that floated all the way up the ridge line.

But there was no fire from the twelve-point-seven gun at the base of the hill. The weapon was firing systematically into the empty air, two hundred meters above the convoy’s roof line, creating the perfect auditory illusion of a heavy ambush for any remote monitoring station listening to the satellite net.

The convoy wasn’t being defended, and it wasn’t being attacked. It was being escorted into a blind box by a script they had just activated with a single match-grade round.

“They’re going to dump it in the dry wash,” Elena said. Her eyes traveled from the road to the narrow, shadow-filled ravine that cut beneath the highway three hundred meters ahead of the lead truck. “If that cargo is what the suspension says it is, they don’t want an explosion on the road. They want it down in the basin where the lime will swallow the residue.”

“We can’t stop four armored trucks with five rounds of seven-point-six-two,” Miller said. He looked down at the heavy rifle slung across her back, his voice flat with the stark, arithmetic certainty of an old logistics sergeant.

“We don’t stop the trucks,” Elena said, her boot already finding the lip of the steep path that led straight down into the throat of the draw. “We find out who signed the manifest on that lead dashboard.”
