No choice.

Suppressing a groan, he wiggled out of his pack and grabbed one item from an inner pocket, palming it.

"Four..."

Gray switched the laptop into dark mode and clicked it closed. If he didn't live, he would have to trust that the computer would serve as witness to the events down here.

"Three..."

Gray crawled out of the mausoleum but remained hidden. He circled to hide his position.

"Two..."

He ducked back onto the main street.

"One..."

He laced his hands atop his head and stepped into sight. "I'm here. Don't shoot!"

10:04 P P.M.

RACHEL WATCHED Gray march up to them at gunpoint. Gray march up to them at gunpoint.

From the hard look on Gray's face, she recognized her error. She had hoped her surrender would buy Gray time to act, to do something to save them, or at least himself. She had not wanted to be the one left alone out in the necropolis, to stand by and watch the others be killed.

And while Kat had given herself up for Monk, the woman had had a rescue plan in place, botched though it may have ended. Rachel, on the other hand, had acted on faith alone, placing all her trust in Gray.

The Dragon Court leader shoved her aside, meeting Gray as he climbed atop the platform. Raoul raised the ma.s.sive horse pistol, pointing it at Gray's chest.

"You've caused me a h.e.l.l of a lot of trouble." He c.o.c.ked the gun. "And no amount of body armor will stop this slug."

Gray ignored him.

His eyes were on Monk, Kat...then Rachel.

He parted his fingers atop his head, revealing a matte-black egg, and said one word.

"Blackout."

10:05 P P.M.

GRAY COUNTED on the full attention of Raoul and his men as the flash grenade exploded above his head. With his eyes squeezed closed, the strobing flare still burned through his lids, a crimson explosion. on the full attention of Raoul and his men as the flash grenade exploded above his head. With his eyes squeezed closed, the strobing flare still burned through his lids, a crimson explosion.

Sightless, he dropped and rolled to the side.

He heard the thunderous bark of Raoul's horse pistol.

Gray reached to his boot and pulled free his .40-caliber Glock.

As the strobe ended, Gray opened his eyes.

One of Raoul's men lay at the foot of the steps, a fist-sized hole through his chest, taking the slug meant for Gray.

Raoul roared and dove off the platform, twisting in midair, shooting blindly back at the platform.

"Down!" Gray yelled.

Major-caliber slugs tore holes through steel.

The others dropped to their knees. Monk's and Kat's hands were still secured behind their backs.

Gray rolled and clipped one dazzled gunman in the ankle, toppling him off the platform. He shot another down at the foot of the steps.

He searched for Raoul. For such a giant of a man, he moved fast. Raoul had landed out of sight, but still blasted at them from below, tearing holes through the meshed floor of the platform.

They were sitting ducks.

Gray had no way of judging how long the flash grenade's effects would last. They had to move.

"Get back!" Gray hissed to the others. "Through the gate!"

Gray fired a volley, covering their retreat, then followed.

Raoul had stopped firing for the moment, reloading. But no doubt he would come at them again with deadly fury.

Shouts arose from deeper in the necropolis. Other gunmen. They were rushing to the aid of their compromised comrades.

What now? He had only one magazine of ammo.

A cry rose behind him.

Gray glanced back. He watched Rachel flailing backward. She must have been half dazzled by the flash bomb. In the darkness, she missed seeing the ramp in front of the tomb and back-stepped into it. She grabbed for Kat's elbow, trying to stop her fall.

But Kat was equally caught off-guard.

Both women tumbled down the ramp and rolled below.

Monk met Gray's eyes. "s.h.i.t."

"Down," Gray said. It was the only shelter. And besides, they had to protect whatever clue lay below.

Monk went first, stumbling with his arms behind his back.

Gray followed as a new barrage began. Chunks of rock were torn from the surface of the tomb. Raoul had reloaded. He meant to keep them away.

Twisting around, Gray's eyes caught on the green light glowing from one of the two plates attached to the tomb. Still activated. He thought quickly and made a choice. He pointed his pistol and fired.

The slug severed the knot of wires running to the plate. The green light winked out.

Gray ran down the stone ramp, noting the immediate cessation of the trembling in the ground. Both ears popped with a sudden release of pressure. The device had shorted.

Immediately a loud grinding sounded underfoot.

Gray dove forward and landed inside a small cavern at the foot of the ramp, a natural pocket, volcanic in origin, common in the hills of Rome.

Behind him, the ramp swung back up, closing.

Gray rolled to his feet, keeping his gun pointed up. As he had hoped, the device's activation had opened the tomb, and likewise its deactivation was closing it. Outside, the barrage by Raoul continued, tearing into rock.

Too late, Gray thought with satisfaction.

With a final grate of stone on stone, the ramp sealed above them.

Darkness settled-but it was not complete.

Gray turned.

The others had gathered around a slab of metallic black rock that rested on the floor. It was lit by a tiny pyre of blue flame atop its surface, rising like a small flume of electrical fire.

Gray approached. There was barely room for the four of them to circle it.

"Hemat.i.te," Kat said, identifying the rock from her background in geology. She glanced from the sealed ramp to the slab. "An iron oxide."

She bent down and studied the silver lines etched into its surface, tiny rivers against a black background, which were illuminated by the blue flames.

As Gray watched, the fire slowly expired, fading to a flicker, then winked out.

Monk drew their attention to a more immediate concern. Another glowing object.

"Over here," he said.

Gray joined him. Resting in a corner of the blind cavern was a familiar silver cylinder, shaped like a barbell. An incendiary grenade. A timer counted down in the dark.

04:28.

04:27.

Gray remembered one of Raoul's bodyguards ducking down here after their leader was done taking photographs. He had been planting the bomb.

"Looks like they intended to destroy this clue," Monk said. He dropped down to one knee, studying the device. "d.a.m.n thing's b.o.o.by-trapped."

Gray glanced to the sealed ramp. Maybe Raoul's barrage a moment ago hadn't been meant to drive them off-but to trap them.

He stared back to the bomb.

With the fiery star on the hemat.i.te slab extinguished, the only light in the cavern glowed from the LCD timer on the incendiary grenade.

04:04.

04:03.

04:02.

10:06 P P.M.

VIGOR HAD felt the sudden release. The wash of electrical fire that had been tearing plaster from the cupola dispersed in seconds. Its energy skittered away like ghostly cerulean spiders. felt the sudden release. The wash of electrical fire that had been tearing plaster from the cupola dispersed in seconds. Its energy skittered away like ghostly cerulean spiders.

Still, chaos reigned inside the basilica. Few noted the cessation of the fireworks. Half the parishioners had managed to flee to safety, but the logjam at the entrances had slowed further evacuation. The Swiss Guard and Vatican Police were doing their best to a.s.sist.

Some people hid under pews. Dozens of other parishioners had been struck by falling plaster and sat with b.l.o.o.d.y fingers pressed to scalp wounds. They were being helped and consoled by a handful of brave individuals, true Christians.

The Swiss Guard had come to the rescue of the pope. But he had refused to abandon the church, acting as the captain of this sinking ship. Cardinal Spera remained at his side. They had evacuated out from under the fiery baldacchino baldacchino and taken shelter in the Clementina Chapel off to the side. and taken shelter in the Clementina Chapel off to the side.

Vigor strode over to join them. He glanced back across the basilica. The chaos was slowly subsiding. Order was being restored. Vigor stared up at the a.s.saulted dome. It had held-whether through the mercy of G.o.d or through the engineering genius of Michelangelo.

As Vigor approached, Cardinal Spera broke through the ranks of the Swiss Guard. "Is it over?"

"I...I don't know," Vigor said honestly. He had a larger concern.

The bones had been ignited. That was plain.

But what did that mean for Rachel and the others?

A new voice intruded, shouted with familiar command. Vigor turned to find a wide-shouldered, silver-haired man striding toward him, dressed in a black uniform, hat under his arm. General Joseph Rende, family friend and head of the local Parioli Station. Vigor now understood why order was being restored. The Carabinieri had responded in full force.

"What is His Holiness still doing here?" Rende asked Vigor, nodding to the pope, who remained ensconced among a clot of black-robed cardinals.

Vigor had no time to explain. He grabbed the general's elbow. "We have to get below. To the Scavi."

Rende frowned. "I just heard word from the station...from Rachel...something about a robbery down there. Then this all happened."

Vigor shook his head. He wanted to scream his panic, but he spoke firmly and steadily. "Gather as many men as you can. We have to get down there. Now!"

To his credit, the general responded immediately, barking crisp commands. Black-uniformed men swiftly ran up, armed with a.s.sault weapons.

"This way!" Vigor said, heading to the sacristy door. The entrance to the Scavi was around back, not far. Still, Vigor could not move fast enough.

Rachel...

10:07 P P.M.

GRAY KNELT with Monk. He had freed both his teammates' wrists with a knife hidden on Kat. Monk had borrowed Gray's night-vision scopes to aid in his study. with Monk. He had freed both his teammates' wrists with a knife hidden on Kat. Monk had borrowed Gray's night-vision scopes to aid in his study.

"Are you sure you can't defuse it?" Gray asked.

"If I had more time...better tools...some G.o.dd.a.m.n decent light..." Monk glanced to him and shook his head.
