Chapter Eight
The explosion wasn't a roar; it was a deep, guttural slap that hit Luke square in the chest, pushing the air straight out of his lungs.
The ceiling of the limestone fissure gave a violent shudder. Above them, centuries of ancient rock groaned as the charge sheared through the supporting natural pillars, raining pulverized white dust and jagged chips of shale down into the dark.
"Move!" Luke roared, his arm sweeping around Maya’s waist as he practically hoisted her onto the narrow, hand-hewn stone steps.
They took the stairs two at a time, the stone slick under their boots with damp moss and pulverized limestone.
Behind them, the subterranean chamber they had just vacated collapsed with the deafening thunder of a landslide—ton after ton of mountain falling inward, burying the wooden worktable, the survey map, and the bloody compression bandages under a tomb of solid rock.
The blast wave chuffed up the stairwell, a wall of hot, sulfur-laced air that blew Luke’s Stetson from his head and slammed them both against the cold, curved wall of the ascent.
Luke instantly spun, throwing his broad back to the falling debris and pinning Maya beneath him against the rock face. He tucked her head under his chin, his large hands cradling the back of her neck as heavy fragments of shale bounced off his leather vest and shoulders.
For ten agonizing seconds, the mountain shook, grinding itself down into silence.
The air turned pitch-black, thick with a blinding cloud of stone dust that choked the back of their throats. The only sound left was the ragged, heavy rasp of Luke’s breathing against her ear and the frantic, hard hammer of Maya’s heart against his ribs.
"Maya," Luke growled softly into her hair, his fingers tightening against her neck, his voice rough with airborne dust and raw adrenaline. "Talk to me, Doc. You hit?"
Maya squeezed her eyes shut against the dust; her forehead pressed hard into the notch of his collarbone. Her gloved hands were clenched tight in the canvas fabric of his western shirt, feeling the massive, steady frame protecting her from the cave-in.
"I'm whole," she breathed, her voice raspy as she tilted her head up in the suffocating gloom. Her dark eyes found his in the faint glow of his fallen tactical light lodged between two steps. "Are you?"
"I'm breathing," Luke grunted.
He didn't move away. In the tight, subterranean darkness, with the smell of cordite and pulverized stone thick around them, the four inches between their bodies felt magnetic. Luke’s dark eyes burned into hers, taking in every line of her face, the smudge of gray limestone dust across her cheek, and the fierce, unyielding courage that had drawn him to her four years ago in Fort Worth.
His thumb came up, brushing along the sharp line of her cheekbone, wiping away the grit. His touch was rough, calloused, but infinitely gentle.
"You should have stayed at the tailgate, Maya," he murmured, his low voice echoing off the narrow stone arch above them. "You almost got buried down here."
"I don't stay behind, Luke. Not four years ago, and not tonight," Maya whispered, her gaze locked onto his lips before rising back to meet his eyes.
"You tried to carry the weight of that Fort Worth investigation by yourself, and it nearly destroyed you.
I'm not letting you go into the dark alone this time. "
Luke’s breath caught, his jaw setting into hard granite. The raw truth of her words sliced cleaner than any blade. He leaned down, his forehead resting lightly against hers, his pulse surging hot and steady.
"Then we stand together," Luke promised softly, the dark vow sealing between them in the crushed stone air. "Now let's find daylight."
Fifty feet further up the spiral staircase, the hand-hewn steps ended at a jagged breach where the mountain met the surface world.
The blast had blown out the side of an old drainage culvert near the upper logging spur. Night air—cold, crisp, and smelling of burnt mountain laurel—rushed into the tunnel, clearing the choking dust.
Luke breached the opening first, his Sig Sauer sweeping the perimeter before he reached down and pulled Maya up onto the flat limestone ledge.
They emerged into a dark, dense thicket of untouched blackjack oak fifty yards above the fire line. Down in the valley, the red strobe lights of the emergency vehicles still painted the smoke, but up here on the high ridge, the night was eerily still.
A low whistle echoed from the shadows fifty feet to their left.
"Grayson! Dr. Lin!"
Cole Remington stepped through the oak brush; his tactical shotgun held low, Buster trotting at his side. The Malinois lifted his head, letting out a soft, low huff of recognition as he caught Luke and Maya’s scent.
"We heard the charge go off under the ridge," Cole said, his sharp eyes quickly assessing both of them for blood or injury. "Felt like a minor earthquake up on the road."
"He blew the main chamber," Luke said, adjusting his holster as he looked down at his dust-covered clothes. "Sealed the lower tunnel permanently. Where’s his truck?"
Cole gestured toward a set of deep, churning mud tracks cutting through the ash on the old logging spur thirty yards away. "He pulled out less than two minutes before the blast. Used a heavy winch to clear a fallen cedar log off the trail and headed north toward the county line."
"Did you catch the rig?" Maya asked, pulling her tablet from her side pack to mark their GPS coordinates.
"Dark grey or brown square-body Ford, early nineties model," Cole reported. "No rear plate, heavy iron ranch bumper. But Buster found something he left behind when he unhooked his winch cable."
Cole stepped aside, pointing his flashlight down at the base of a charred stump.
Lying in the soot was a discarded, blood-stained shop rag and a crumpled yellow paper slip—a state-issued fuel receipt from a commercial truck stop off Highway 180 in Mineral Wells, timestamped five hours ago.
Maya dropped to one knee, pulling out a pair of sterile tweezers and a specimen bag from her tactical kit. She carefully picked up the receipt, aiming her light at the faint, handwritten account code penned across the bottom margin.
"It’s not paid in cash," Maya said, her eyes widening as she analyzed the ink under her light. "It’s billed to a commercial land holding corporation out of Granbury."
Luke stepped over her shoulder, his shadow falling long over the ash. "What’s the name on the account, Maya?"
"Brazos Valley Development Group," Maya read aloud, her voice dropping into a cold, chilling register. "The same parent company that owned the land rights around Nora’s ranch in Hood County."
A cold wind whipped through the oak thicket, carrying the lingering scent of smoke across the ridge line.
Luke looked out over the dark valley toward the winding ribbon of the river in the distance.
The pieces of the puzzle were locking together with terrifying precision: the 1990s cold cases, the murdered state troopers, the land grabs in Hood County, and the hidden vault in Devil’s Hollow weren’t isolated crimes.
They were the blood-soaked foundation of a thirty-year empire built along the riverbanks.
Luke reached down, his strong hand taking Maya’s gloved fingers and pulling her smoothly to her feet. He didn't let go of her hand, his grip solid, warm, and possessive in the cold night.
"Get on the horn to Sheriff Mercer, Cole," Luke commanded, his dark eyes burning with lethal, unyielding resolve. "Tell him we have a paper trail. And tell him the man who murdered his brother isn't a ghost... he’s a landlord."
