Map of Bones (Sigma Force 2)

Soon after the excavation of the necropolis began, the original Constantinian cube was rediscovered, positioned directly under the main papal altar of St. Peter’s. A wall of the original temple remained, scratched and scrawled with Christian graffiti, including the Greek letters spelling out Petros eni, or “Peter is within.”

And indeed, inside a cavity in that graffiti wall, bones and cloth were found that matched a man of Saint Peter’s stature and age. Now they were sealed in bulletproof plastic boxes made, oddly enough, by the U.S. Department of Defense and secured back into the wall cavity.

That was their goal.

“This way,” Rachel whispered, and pointed to a steep, circular stair that led below.

Gray took the lead.

They wound down below the basement and even deeper.

A chill settled through Rachel’s clothes. She felt almost naked. The goggles narrowed her vision, triggering a twinge of claustrophobia.

At the bottom of the stairs, a small door blocked the way. Rachel squeezed next to Gray, bodies touching, and noted his musky scent before she fished out the key and unlocked the door.

He held her hand against opening the door and gently but firmly pushed her behind him. He then pulled the door open a few centimeters and stared through. Rachel and the others waited.

“All clear,” he said. “Dark as a tomb in there.”

“Funny,” Monk grumbled.

Gray pulled open the door.

Rachel readied herself for a blast, gunfire, or some sort of attack, but found only silence.

As they all pushed inside, Gray turned to the group. “I think the monsignor was right. For once, we’ve got the jump on the Dragon Court. It’s about time we set up the ambush.”

“What’s the plan?” Monk asked.

“No chances. We set the trap and get the hell out of here.” Gray pointed to the door. “Monk, stand guard at the door. It’s the only way out or in. Guard our exit and our backs.”

“Not a problem.”

Gray handed what looked like two small egg cartons to Kat. “Sonic grenades and flash bombs. I expect they’ll come in dark like we did, with their ears up. Let’s see if we can blind and deafen them. Distribute these as we cross to the tomb. Full coverage.”

Kat nodded.

He turned next to Rachel. “Show me Saint Peter’s tomb.”

She headed out into the dark necropolis, walking along an ancient Roman road. Family crypts and mausoleums lined the path, each six meters square. Walls were covered with ultrathin bricks, a common building material during the first century. Frescoes and mosaics decorated many of the tombs, but such details were murky under night-vision. There remained a few bits of statuary, appearing to move in the eerie illumination. The dead come to life.

Rachel mapped out the route to the center of the necropolis. A metal walkway led up to a platform and rectangular window. She pointed through it.

“The tomb of Saint Peter.”

9:40 P.M.

GRAY POINTED his pistol and shone his UV spot into the gravesite.

Ten feet beyond the window, a brick wall rose alongside a massive cube of marble. A hole near the base of the wall had an opening in it. Bending down, he aimed his light. Within the opening, he could see a clear box with a blob of white claylike material.

Bone.

From Saint Peter.

Gray felt the hairs on his arms stand a bit on end, a shiver of awe and fear. He felt like an archaeologist, delving into a dark cave, out in some lost continent, not a couple floors below the heart of the Roman Catholic Church. Then again, maybe here was its true heart.

“Commander?” Kat asked. She rejoined them, having lagged a bit behind to plant her charges.

Gray straightened. “Can we get closer?” he asked Rachel.

She pulled out the second key her uncle had given her and unlocked a gate that led into the inner sanctum.

“We must be quick,” Gray said, sensing time was running short. Then again, maybe it wasn’t. Maybe the Dragon Court wouldn’t strike until after midnight, like in Cologne. But he was taking no chances.

He pulled out the gear he had been calibrating on the way here. He searched the space and found an inconspicuous spot. He fixed the tiny video camera within a crevice of a neighboring mausoleum and positioned it to face Saint Peter’s tomb. He took a second camera and turned it the opposite way, making sure it faced back out through the window to cover the approach.

“What are you doing?” Rachel asked.

Finished with the cameras, Gray waved them back out. “I don’t want to spring the trap too soon. I want them to get comfortable in here, set up their apparatus. Then we’ll strike. I don’t want to leave them any room to bolt with the Magi bones or their device.”

After they exited, Rachel relocked the gate.

“Monk,” Gray said into his radio, “how are you doing?”

“All quiet.”

Good.

Gray crossed to a nearby crumbling mausoleum, one open at the front. The bones had long been cleared out. He freed the laptop from his pack and hid it inside the mausoleum, attaching a portable boost-transmitter to its USB port. A green light flashed a positive connection. He flicked a switch, sending the apparatus into dark mode. No light shone from computer or transmitter. Good.

Gray straightened and explained as they headed back out. “The video cameras are not strong enough to transmit very far. The laptop will pick up the signal and boost it. It’ll have enough range to reach the surface. We’ll monitor it on another laptop. Once the Court is down here, trapped, we blast them with the sonic and flash charges, then sweep below with a whole barrack of Swiss Guards.”

Kat nodded and eyed him. “If we had been too cautious back at the catacombs, delayed too long, we wouldn’t have had this chance.”

Gray nodded.

Finally luck was with them. A bit of boldness had—

The explosions cut off his thought. They were not loud, more muffled, sounding like depth charges exploding far underwater. They echoed throughout the necropolis, accompanied by a louder crash of stone.

Gray crouched as small holes were punched through the roof from above. Rock and earth blasted downward, crashing into the mausoleums and crypts below. Before the debris could even settle, ropes snaked through the smoky openings, followed by one man after another.

A full assault team.

They dropped into the necropolis and vanished.

Gray immediately recognized what was happening. The Dragon Court was entering from the floor above, the Sacred Grottoes. That level was accessed from inside the basilica. The Dragon Court must have come to the memorial service—then through their contact here, snuck below into the papal crypts of the Sacred Grotto. Their gear had probably been smuggled in over the course of a couple days and hidden among the shadowy tombs of the Grotto. Then, under the cover of the service, they regained their tools, bored specially shaped charges, and quietly punched their way down here.
