The Devil Colony (Sigma Force 7)

She finally freed the latches and hauled the top open. With the rain falling, she would not expose the artifact for longer than a minute. She stared down at the gold skull nestled in its foam cocoon. Even in the wan light down here, it shone brilliantly.

She stepped back to open the view to the cameras and the crowd, but she could not take her eyes off the skull. A misty haze coalesced over its surface. She watched a drop of rain strike the golden surface—then freeze immediately into an icy teardrop.

A collective gasp rose from the crowd behind her.

She thought they’d witnessed the event, too—then she heard a scuff of boot on rock. She glanced up to see a thin girl in black jeans and jacket come leaping out of the cave a yard away, her ebony hair fanning out like wings of a raven. She clutched an arm around her jacket, but something slipped from beneath it and hit the stone with a clanging thud.

It was one of the gold tablets.

Ryan shouted for the thief to halt.

Ignoring him, the girl turned, ready to flee toward the woods, but her foot slipped on the rain-dampened stone outside the cave. She stumbled, one arm pinwheeling for balance, sending her backpack tumbling. It rolled and came to rest near the crate. The girl came close to crashing down after it, but she gained her footing as effortlessly as a startled deer, turned on a toe, and leaped toward the edge of the forest.

Maggie remained fixed in place, crouched over the open crate to protect it. She stared down, making sure the artifact was safe. In that short time, more raindrops had fallen—and frozen—decorating the golden surface with beads of ice.

She reached and foolishly touched one, triggering a stinging snap. A painful jolt shot up her arm, but instead of being thrown back, she felt her arm pulled forward. Her palm struck the golden surface. With contact, the bones of her fingers suddenly ignited, burning through her flesh. Shock and horror clamped her throat shut. Her knees weakened.

She heard Hank shout at her.

Ryan bellowed, too.

One word cut through the agony.

Bomb!

12:34 P.M.

The brilliant flash blinded Hank. One moment he was shouting at Maggie, the next his vision went white. A clap of thunder tried to crush his skull, immediately deafening him. An icy shock wave knocked him back like a cold slap from God. He hit the ground on his back, then he felt a strange tug on his body, pulling him toward the explosion.

He fought against it, panicked down to the core. The sensation felt not only wrong, but fundamentally unnatural. He struggled against that tide with every fiber of his being.

Then it was over, as quickly as it had begun.

The inexorable pull popped away, releasing him. His senses snapped back. His ears filled with wails and screams. Images swirled into focus. He lay on his side, facing toward where Maggie had stood. He didn’t move, too stunned.

She was gone—so were the crate, the skull, and most of the cliff, including the cave entrance.

He raised up to an elbow and searched.

There was no sign of her, no charred remains, no mangled body. Nothing but a blackened circle of steaming rock.

He struggled up. Kawtch shimmied closer on his belly, cowering, tail between his leg. If Hank had a tail, he’d have done the same. He placed a reassuring palm on the dog’s side.

“It’ll be okay.”

He hoped it was true.

By now, the crowd had regained its collective footing. A panicked exodus began. The news crew retreated to higher ground, shuffled back by a cordon of National Guard. Two soldiers manhandled the governor up the trail, a precaution in case there was another attack.

Harry pictured the bag tossed by the girl. When it had landed by the crate, it had flapped open and its contents spilled out: cubes of yellowish-gray clay, embedded with wires.

Major Ryan had immediately recognized the threat.

Bomb.

But the warning had come too late for Maggie.

A knot of anger burned in the pit of his belly. He let it settle there as he pictured the attacker. From the girl’s burnished copper skin, brown eyes, and black hair, she was definitely Native American. A homegrown terrorist. As if matters here weren’t bad enough.

Numb with grief, he stumbled toward the blast zone, needing to understand. To the side, Major Ryan picked up his helmet and placed it back on his head.

“I’ve never seen anything like this,” Ryan said, still dazed. “The force of this explosion should have taken out half the crowd. Including us.” He held up an open palm. “And just feel that heat.”

Hank did. It felt like a blast furnace. The air reeked of burning brimstone, turning his stomach.

As they watched, a large boulder crumbled apart within the blast zone, breaking down into smaller rocks. The face of the cliff began to do the same, disintegrating into a flow of boulders and sand. It was as if the hard granite had become loose sandstone, friable and weak.

“Look at the ground,” Ryan said.

Hank stared at the blasted rock, steaming and awash with a swirl of mist. The drizzling rain hissed and spattered as it struck. Still, he didn’t see what had Major Ryan so agitated. Then again, the man had much younger eyes.

Hank dropped to a knee to inspect the ground more closely. Then he saw it, too. He’d missed it through the swirl of steam. The stone surface wasn’t solid, more like ground pepper—and it was moving!

The grains jittered and trembled as if they were drops of oil simmering atop a hot skillet. He watched a small pebble on the surface dissolve into coarse sand, then into a dusty powder. A drop of rain struck the ground and blasted a crater. Like a pebble hitting a still pond, ripples spread outward across the microfine surface

Hank shook his head in disbelief. Fearful, he studied where the blast zone ended and solid ground began. As he stared, the bordering edge of stone crumbled to sand, incrementally expanding the blast zone.

“It’s spreading,” Hank realized, and pushed Ryan back.

“What are you talking about?”

Hank had no answers, only a growing certainty. “Something is still active. It’s eating away the rock and radiating outward.”

“Are you nuts? Nothing can—”

From the center of the blast zone, a belch of water burst upward from below and coughed into a steaming column, rising several yards into the air. A scalding heat chased them farther off.

By the time they stopped, Hank’s skin burned, and his eyes felt parboiled. He gasped and choked out a few words.

“Must’ve cracked into the geothermal spring . . . under the valley.”

“What are you talking about?” Ryan pulled his jacket collar over his mouth and nose. The burning sulfur made even breathing dangerous.
