Krista stood next to Khattab as the team's demolition expert finished packing the last hole with C-4 plastic explosive. He worked it with his fingers and shaped the charge with the deft skill of a sculptor. Once satisfied, he inserted a spark detonator tied to a wireless transmitter.
He waved everyone back.
They retreated out into the garden.
No one wanted to be under the walkway when it blew. The expert had warned that there was a chance the blast could collapse the walkway and bury the secret entrance.
'Ready?' Khattab asked.
She waved impatiently.
With a nod from Khattab, the demolitions expert lifted his transmitter and pushed the button.
3:49 P.M.
The blast dropped Rachel to one knee-not from any concussion, but from sheer fright. Already tense, she was caught off guard by the explosion. The meters of rock muffled the blast, but it still sounded like a gunshot.
'They're trying to blow their way inside,' Seichan said, staring back at the tunnel.
'On it!' Kowalski called and ran with his rifle up the tunnel. But he was only one man against an army.
Already on one knee, Rachel slumped and sat on the floor. Her fever had grown worse. Chills shook through her. Her head pounded, as if her brain were expanding and contracting with each beat of her heart. She also could no longer ignore the nausea.
Gray stared over at her. She waved for him to continue his study of the cross. He had spent the past ten minutes examining the cross without touching it. He circled around and around. Sometimes he leaned close; other times he pulled back and stared off into space.
They had noted a few oddities about the cross. The horizontal crosspiece was hollow. And behind the cross, Wallace had discovered a long string pinned to the middle of the cross. It was dried sinew braided into a thick cord and weighted down at the end by a triangular chunk of bronze.
No one knew what to make of it-and no one dared touch it.
A pounding of boots announced Kowalski's return. 'They didn't make it through,' he shouted with relief. 'We're still locked up tight.'
'They'll keep trying,' Seichan warned.
Rachel stared over at Gray. They were running out of time.
For the moment, Gray had stopped. He slowly sank to the floor, as if giving up.
But she knew him better than that.
At least she hoped she did.
3:59 P.M.
Krista held the phone to her ear. She hadn't wanted to take the call, but she had no choice. A palm was clamped hard over her other ear. The sirens still blared. And the firefight had grown louder from the prison yards. It sounded like an all-out war. She knew the fighting threatened to spill at any time into their isolated oasis.
'We know where they are!' she yelled into the phone, trying to keep the desperation out of her voice. 'We'll have the passage blown open in the next ten minutes.'
She glanced over at the walkway. Khattab monitored the demolition expert's handiwork. The Algerian noted her attention. He held up ten fingers, confirming her guess.
It was their second attempt. They had blasted a crater into the walkway and exposed a buried set of limestone slabs. She knew they were close and cursed the caution of their explosives expert.
Still, from the blackened wall and columns, she recognized the need. If they accidentally collapsed the walkway over the hidden entrance, they would never get down there.
The man on the line finally spoke. His voice was gratingly calm, unhurried. 'And you believe they've accessed some vault that might hold the Doomsday key?'
'I do!'
At least she hoped like hell they had.
There was a long pause on the phone, as if she had all the time in the world. Off to the side, sharper rifle blasts erupted. They came from her own team. That could only mean one thing-the war was beginning to break through to them.
'Fair enough,' the man finally said. 'Secure the key.'
There was no need to threaten.
The line clicked dead.
She stared over at Khattab.
He held up nine fingers.
4:00 P.M.
Father Giovanni must have known something.
That was all Gray had to go on.
He sat with his eyes open, but he was blind to everything around him. He placed himself back in the crypt beneath Saint Mary's Abbey on Bardsey Island. He pictured the charcoal markings on the wall. In his mind, he again read the notations scribbled by the priest and studied the large circle drawn around the cross. Other lines bisected and sectioned the circle.
At the same time, he pictured the cross here. He remembered his first impression, trusting it. He had thought it looked more like an industrial tool than a religious symbol. Like a bronze timepiece, a device crafted for purpose, not decoration.
Wallace's description of the Cistercian order echoed in his ears.
Everything in its place and serving its function.
He craned his neck and stared up at the quartz starscape. Breathing through his nose, he felt something rising up inside, some understanding that he couldn't quite put into words.
Then he was on his feet. He never remembered rising. He stepped back over to the cross. He stared at it from the side. The bronze sculpture was only a bit taller than Gray. It required him to crouch to peer through the hollow crosspiece.
'It's not a cross,' he mumbled.
'What do you mean?' Wallace asked from the other side.
Gray shook away any response. He didn't understand, not completely yet. He bent down and stared through the hollow arm.
Seichan stood at his shoulder. 'It's almost like a telescope.'
Gray straightened, stunned.
That was it.
That was the one piece he needed.
Inside, a dam suddenly released, understanding flowed through Gray's head. Images flashed across his mind's eye faster than he could follow, but still, somewhere beyond reason, they came together.
He stared up at the roof.
Like a telescope.
He turned and grasped his enemy in a hug. Seichan stiffened, unsure what to do with her arms.
'I know,' he whispered in her ear.
She jolted at his words, perhaps misinterpreting them.
He let her go. He dropped to the floor and checked the base of the cross. It sat on a half sphere of bronze. He felt around the edges. It wasn't flush. There was a wafer-thin gap between the stone and the bronze.
He sprang back to his feet and ran for the pack he'd abandoned on the floor. He dumped it out and found a black marker. He knelt down, needing to see it for himself. He worked quickly, his marker flying across the stone.
As he worked, a part of his mind traveled back to Bardsey. He recognized the partial calculations on the wall now. The circle with the lines. Father Giovanni was smarter than all of them. He had figured it out. The circle was a representation of the earth. His notations-
'They were calculations of longitude and latitude.'
The others gathered around him.
'What are you talking about?' Wallace asked.
