The Doomsday Key (50 page)

His sketch showed how the cross could be tilted, how its arm could be pointed at a star, how the weighted sinew could act like a plumb line, and the turning wheel of the device could measure degrees.

“It’s an early sextant,” he explained.

“Oh my God.” Wallace fell back in shock. A palm rose to his forehead. “For the longest time, archaeologists have debated how the ancients were so accurate in positioning their stones. How precisely they were able to align them!” He stabbed a finger at the drawing. “Bloody hell! That device could even be a theodolite!”

“A what?” Rachel asked.

Gray answered, recognizing it now, too. “A surveying tool, used to measure horizontal and vertical angles. Used in engineering.”

“The worship of the spiral and the cross,” Wallace said. “The symbols truly do represent the heavens and the earth.”

Gray stared down at his sketch of the earthbound cross pointed at the stars. “It’s more than that. The symbols also represent the worship of secret knowledge,
the secrets of navigation and engineering.”

Seichan brought them back down out of the stars with a sobering question. “But what does all this have to do with the Doomsday key?”

They all stared toward the bronze cross.

Gray knew the answer. “In ancient times, only the priest classes had access to such powerful knowledge.” He glanced at Wallace for confirmation.

The professor nodded.

“To unlock the Doomsday key, we have to demonstrate that same knowledge.”

“How?” Rachel asked.

He remembered what Father Giovanni had been calculating at Bardsey. “We have to use the stars above and calculate a navigational coordinate. I’m guessing we have to dial in our location here. An approximate longitude and latitude.” He faced the others. “That’s the combination.”

“Can you calculate it?” Wallace asked.

“I can try.”

Gray returned to the floor. The Celtic cross functioned differently from a sextant, which used mirrors and reflections to discern latitude and longitude. But it wasn’t that dissimilar.

“I need a fixed constant,” he mumbled and stared up at the quartz starscape. It had been put there for a reason.

“The north star,” Seichan said. She crouched and pointed to the chunk of quartz that represented the pole star, used over countless ages for navigation.

That would do.

He worked quickly. He knew the approximate coordinates for Clairvaux from using his GPS during the drive here. He pictured the reading from the unit:

LAT 48°09’00"N
LONG 04°’00"E

Longitude and latitude measurements were broken down to hours, minutes, and seconds. Just sweeps around a clock. Like the lines scored into the spinning wheel of bronze on the cross. It was all proportional.

In under a minute, he had what he believed were the correct assignments using the ancient tool and their current location.

He memorized them and stood up.

Rachel stared at him, her eyes hopeful.

Gray prayed he was equal to that hope. “In case I’m wrong, you all might want to retreat back to the tunnel.”

He hurried over to the cross. As he reached it, he suddenly grew less sure. He would have only one chance. If he was wrong, if he miscalculated, if he failed to manipulate the ancient sextant correctly, the others were all dead.

He stopped and stared at the device.

“You can do it,” a voice said behind him.

He glanced over his shoulder. Seichan stood there. The others had joined Kowalski in the tunnel. “Get back,” he said harshly.

She ignored him, not even reacting. “It may take two people. One to hold the cross steady at the proper angle, the other to dial the combination with the wheel.”

He wanted to argue, but he recognized she was right. A part of him also had to admit that he didn’t want to be alone.

“Let’s do it then,” he said.

Gray again crouched to peer through the hollow arm of the cross.
Like a telescope,
he thought, remembering how the words had unlocked the knowledge inside him. They had come from Seichan.

He knew what had to be done. He reached to the cross and pulled the arm down. The entire sculpture tilted, pivoting on the spherical base. As soon as he moved it, a massive
clank
echoed up from under the floor.

There was no turning back.

Gray swung the arm so it pointed north. Staring through the barrel of the armpiece, he searched the starry dome. Seichan helped by keeping her flashlight pointed at the chunk of quartz that marked the north star.

After a moment of searching, he spotted the star and centered the scope on it. As he did so, a loud gong sounded. It came from overhead and reverberated through the space.

What did that mean?

From the roof, hundreds of stone plugs popped free and rained down. One struck Gray on the shoulder. Startled, he almost dropped the cross. Seichan swore and pressed a hand to her forehead. Blood seeped between her fingers.

She continued to stare up.

Gray followed her line of sight. From the roof, bronze spikes pushed out of a hundred holes. They lowered swiftly on long poles toward the floor. Behind them, a slab of stone dropped over the tunnel exit.

Gray and Seichan would never make it to the door in time.

It was a reverse of the trap at Bardsey. Instead of being dumped atop a sea of spikes, they were to be impaled from above.

Either way, the meaning was the same.

Gray had failed.

Clairvaux, France

“Are you sure this will blow that secret passage open?” Krista asked.

The demolition was taking longer than expected. After further calculations, the munitions expert had wanted to drill more holes into the crater, to spread the charges out for a more controlled blast.

The man shrugged as he worked. He was using an awl to hand drill the last of his mouse holes. The cubes of C-4 still waited to be molded and packed. He answered in Arabic. Her second-in-command translated.

“He says that it will blow open only if Allah wishes it.”

Krista had her hand clutched on her holstered pistol.
Allah had better wish it, or that bastard was going to get a bullet through his skull.

“How much longer?” she asked instead.

“Still another ten minutes.”

Krista wanted to scream, but she simply turned and strode away.

Overhead, one of the helicopters swept past. Its rotors stirred the thick pall of smoke. Sunlight dappled brighter, then sank back to a murky twilight. The air reeked of oil fires and cordite.

She heard the helicopter’s guns chatter as it sped toward the skirmish line. Her forces fought to keep the prison war from spilling over them. Orders were bellowed. Men cried and screamed. The fighting was unusually brutal. She watched one of her commandos drag a fellow soldier into the cloister. The man on the ground writhed, pressing his guts into his belly with a fist.

Like the fallen soldier, they couldn’t hold out forever.

She turned to Khattab.

He raised nine fingers.

She took a deep breath to calm herself. They could last that long. Once the tunnel was opened, she was going down that hole and laying waste to all that stood between her and the key.

She glanced down to the suitcase at her feet.

Nothing would stop her.

4:05 P.M.

Seichan steadied Gray with a hand on his shoulder. He had stepped away from the cross, but he continued to hold it with one arm. She knew what he was thinking as he stared up at the spears sweeping down from above. Lines of agony etched his face.

“Should I yank the lever?” Kowalski hollered. He was on his knees, yelling under the closing slab of rock as it sealed the only exit.

“No!” Gray called back.

The others were safely in the tunnel, out of immediate danger from the impaling spikes. Only she and Gray were at risk. She knew the choice Gray had to make. If the lever was yanked, the trap would reset, but it might also open the secret door, allowing the soldiers to flood inside. If they saved themselves, the others would die.

There was no winning here.

All Gray’s decision did was buy the others a slim chance. If Krista’s forces were chased off before the door was blown open, the others might still live.

It was long odds, but it was a chance.

She stared upward.

She would take those odds right now.

Seichan stopped and faced Gray. She drew his eyes from the death descending on them. He had to know the truth.

What did secrets matter now?

But Gray suddenly twisted away. “What if I wasn’t wrong?”

“What?”

“Hold the cross steady while I turn the wheel,” he ordered.

She obeyed, baffled.

“Maybe it’s
not
a booby trap. Maybe it’s a timer. Once you attempt to solve the combination, you’re allowed only a certain length of time to complete it.” He motioned to the roof of spikes.

“So we’re not allowed to guess. No trial and error.”

“Exactly.”

Gray reached to the weighted string of sinew and made sure it draped smoothly. He ran his fingers along the wheel of the cross. His lips moved as he counted the marks. He reached a spot that must have corresponded to his calculation.

“Here goes,” he whispered.

He gripped the wheel and turned it until the spot he marked drew even with the weighted plumb line. He stopped and held his breath, his lips stretched thin with tension.

A gong sounded like before.

“That’s got to be it!” he said.

Unfortunately, the spikes dropped even faster now. They plummeted toward the floor.

“Gray!”

He saw and counted quickly. Out loud this time. “Eight, seven, six, five,
four.”

Reaching the proper mark, he held his finger there and spun the wheel the other way. It required turning it almost a full circle.

Seichan ducked as a spike headed for her face. They were both driven to their knees. Seichan held one arm high, supporting the cross. Gray had both limbs up: one to hold the marked position, the other to spin the wheel.

As she watched, a spear point sliced along her arm.

Gray cried out as a spike stabbed into the back of his hand and pushed his arm off the wheel.

Kneeling in a slightly different position, Seichan snaked her arm between two spikes and got her hand on another section of the wheel.

“Tell me when to stop turning!” she gasped out.

It required shifting up to gain leverage. The wheel was hard to spin. She pressed her cheek into a spike. It pierced all the way through. Blood filled her mouth, flowed down her neck.

She struggled to turn the wheel, but it was too tight.

Panicked, her eyes caught Gray’s. She couldn’t talk with her cheek impaled. Agony wracked her. She willed all her grief and agony into that one glance, bared herself to the man, hiding nothing for once.

Not even her heart.

His eyes widened, perhaps truly seeing her for the first time, recognizing what lay hidden between them. A hand crossed that gulf and found her leg. He squeezed her knee and whispered three words that no one had ever uttered to her and meant.

“I trust you.”

What pain failed to do, his words accomplished. Tears welled and flowed down her cheeks. She pushed into the spear, driving it deeper. Her fingers gripped harder. She tugged on the wheel. It slowly turned.

Time stretched to a razor’s edge.

Pain tore through her.

She felt the spear tip on her tongue.

Still, she turned.

“Stop!” Gray finally called out.

She let go. She slumped, sliding off the impaling spear and onto the floor. Distantly, a third gong sounded.

Three spirals, three gongs.

Her vision darkened at the edges, but she saw the spikes pull back, retracting slowly toward the roof. With her skull on the floor, she heard huge gears turning below, like listening to God’s pocket watch.

Closer at hand, the cross straightened and righted itself.

Gray was suddenly at her side. He scooped her up and dragged her onto his lap. She curled around him, hugging him. He held her tight.

“You did it. Look.”

He lifted her higher in his arms. She stared out across the room.

As the gears wound below, each of the three spirals began to flip, revealing
false floors. The sections rotated full around. The spiral sides vanished, turning upside down to reveal what had been hidden for all these centuries.

Bolted to the underside of each floor was a glass cradle.

As the three floors settled to a stop, the three cradles swung in their stanchions.

Even from here, Seichan knew they weren’t
babies
in those oversized cradles, but
bodies.

The cradles were actually caskets.

“It’s the tombs,” Gray said.

Across the chamber, the door unsealed, and the slab pulled back up. The others rushed into the chamber.

Wallace’s eyes were huge. “You did it!”

“Gray …?” Rachel called out.

Tears streamed down her face. She must have thought he was dead. Relief and horror mixed in her expression at finding him alive but covered in blood.

Seichan tried to stand but was too weak.

Gray lifted her to her feet. He supported her with one arm. Blood still flowed from her stabbed cheek, but not as heavily. Wallace offered his handkerchief. She balled it up and pressed it to her face.

Gray stared at her, his eyes questioning. She nodded and took a stumbling step out of his arms. It was the hardest thing she’d ever done. But she didn’t belong there.

Rachel rushed to him and helped bind Gray’s hand.

Wallace came with Kowalski. “They’re glass coffins …”

“Of course they are,” Kowalski said.

Gray gave his bandage a final cinch. Blood still dripped from his fingertips as he pointed toward the tombs. “We need to find that key.”

4:08 P.M.

Gray knew where to look first.
