James Rollins - Map of Bones

And now he had to take a leak.

He’d better cut off the diet Cokes.

Motion caught his eye. Coming around the far side of the peninsula. A large sleek ship, midnight blue. Thirty-footer. He read the lines. Not an ordinary ship. Hydrofoil. It raced over the waters, slightly raised on its surface-piercing skids. It flew unimpeded over the slight waves, skimming like a sled on ice.

Crap, it was fast.

He followed its curve around the spit of land, a quarter klick out. It aimed toward the East Harbor. It was too small for a ferry shuttle. Maybe some rich A-rab’s private yacht. He raised a pair of binoculars and searched for the ship. It took an extra moment to pin down the boat.

In the bow, he spotted a pair of girls in bikinis. No burka-wrapped modesty here. Monk had already surveyed a few of the other boats around the harbor, fixing them in place in his mental chessboard. One mini-yacht had a party in full swing, champagne flowing. Another houseboat-like craft had an older couple lounging about buck naked. Apparently Alexandria was the Fort Lauderdale of Egypt.

“Monk,” Kat called from the radio.

He wore a headset connected to the underwater transceiver. “What is it, Kat?”

“I’m picking up a pulsing note of static over the radio. Is that you?”

He lowered the binoculars. “It’s not me. I’ll run a diagnostic on the transceiver. You might be picking up someone’s fish finder.”

“Roger that.”

Monk glanced across the water. The hydrofoil slowed and settled deeper into the water. It had drifted to the far side of the harbor.

Good.

Monk fixed its berth among the other boats in his head, one more piece to the chessboard. He turned his attention to the Buddy Phone transceiver. He twisted the amplitude control, earning a feedback whine in his ear, then reset the channel.

“How’s that?” he asked.

Kat answered. “Better. It’s gone now.”

Monk shook his head. Damn rental equipment …

“Let me know if it returns,” he said.

“Will do. Thanks.”

Monk eyed the length of her form on the camera screen and sighed. What was the use? He picked up his binoculars. Where were those two bikini-clad girls?

RACHEL STEPPED last into the chamber. The two men parted to either side in front of her. Despite Gray’s warning to conserve their batteries, Uncle Vigor had flicked on his own flashlight.

The spears of light illuminated another drum-shaped room, domed above. The ceiling plaster had been painted black. Silver stars glowed brightly against the dark background. But the stars had not been painted onto the ceiling. They were metallic inlays.

The ceiling was reflected in a still pool of water that covered the entire floor. It looked knee-deep. The effect of the mirrored image in the water created a mirage of a perfect sphere of stars, above and below.

But that still wasn’t the most amazing sight.

Resting in the middle of the chamber, rising from the pool of water, stood a giant pyramid of glass, as tall as a man. It seemed to float in the center of the phantom sphere.

The glass pyramid glinted with a familiar golden hue.

“Could it be…?” Uncle Vigor muttered.

“Gold glass,” Gray said. “A giant superconductor.”

They spread out along the narrow lip of stone that surrounded the pool. Four copper pots rested in the water at the edges of the pools. Her uncle inspected one, then moved on. Ancient lamps, Rachel guessed. But they had brought their own illumination.

She studied the structure in the middle of the pool. The pyramid was square-bottomed, four-sided, like the pyramids of Giza.

“Something’s inside it,” Rachel said.

The reflection off the glass surfaces of the pyramid made details inside difficult to discern. Rachel hopped into the water. It was a little deeper than her knees.

“Careful,” Gray said.

“Like you’d take that advice,” she shot back, wading toward the pyramid.

Splashes behind her announced the others were following. They crossed to the glass structure. Her uncle and Gray repositioned their lamps to penetrate the pyramid.

Two shapes appeared.

One stood in the exact center of the pyramid. It was a bronze sculpture of a giant finger, raised and pointing up. So large, she doubted she could get her arms around it. The detail work was masterful, from the trimmed fingernail down to the wrinkles at the knuckles.

But it was the shape below the raised finger that drew most of her attention. A figure, crowned and masked in gold, robed in a flow of white gown, lay atop a stone altar. The arms outstretched to either side, Christlike. But the golden face was distinctly Greek.

Rachel turned to her uncle. “Alexander the Great.”

Her uncle stepped slowly around, getting a view from all angles. His eyes glistened with tears. “His tomb…the historical record mentioned his last resting place was in glass.” He reached to touch one of the outstretched hands, buried only a few centimeters into the glass, then thought better of it and lowered his arm.

“What’s with the bronze finger?” Gray asked.

Uncle Vigor stepped back to them. “I…I think it’s from the Colossus of Rhodes, the giant statue that spanned the island’s harbor. It represented the god Helios but was modeled after Alexander the Great. No part of the statue was thought to still exist.”

“Now this last remnant has become Alexander’s headstone,” Rachel said.

“I think all of this is a testament to Alexander,” her uncle said. “And to the science and knowledge he helped foster. It was at the Library of Alexandria that Euclid discovered the rules of geometry. All around here are triangles, pyramids, circles.”

Uncle Vigor then pointed up and down. “The reflected sphere split by water harkens to Eratosthenes, who at Alexandria calculated the diameter of the Earth. Even the water here…it must be fed through small channels to keep this pool full. It was at the library that Archimedes designed the first screw-shaped water pump, which is still in use today.”

Her uncle shook his head at the wonder. “All of this is a monument to Alexander and the lost Library of Alexandria.”

That reminded Rachel of something. “Weren’t there supposed to be books down here? Didn’t Septimus bury the most important scrolls of the library down here?”

Vigor searched around. “They must have been cleared out after the quake. When the clues were planted here. The knowledge must’ve been taken and sent to whatever hidden vault we seek. We must be close.”

Rachel heard the quaver in her uncle’s voice. What else might they discover?

“But before we move on,” Gray said, “we first must solve this riddle.”

“No,” Uncle Vigor said. “The riddle is not even exposed yet. Remember at St. Peter’s. We must pass some test. Prove our knowledge, like the Dragon Court did with their understanding of magnetism. Only after that was the secret revealed.”

“Then what are we supposed to do?” Gray asked.

Uncle Vigor stepped back, his eyes on the pyramid. “We have to activate this pyramid.”

“And how do we go about doing that?” Gray asked.

Vigor turned to Gray. “I need some soda.”

GRAY WAITED for Kat to ferry up the last of the cans of Coke. They needed two more six-packs. “Does it matter if it’s diet Coke or regular?” Gray asked.

“No,” Vigor said. “I just need something acidic. Even citrus juice would work, or vinegar.”

Gray glanced to Rachel. She just shook her head and shrugged.

“Would you care to explain now?” Gray asked.

“Remember how magnetism opened the first tomb,” Vigor said. “We know that the ancients were well aware of magnetism. Lodestones were widely distributed and used. Chinese compasses date back to 200 B.C. To move forward, we had to prove our understanding of magnetism. It even led us here. A magnetic marker left underwater.”
