countless precious artifacts: swords and spears and shields and amphorae of silver and clay. White marble had been inlaid into the far wall, a lengthy inscription carved into it, though too distant for him to make out what it said.
But it was the left-hand wall that mesmerized Knox. It was a huge mosaic, framed at the top by turquoise-painted plaster that represented the sky, and which contoured the main subject matter like a chalk mark around a corpse. Thirty-three men, clearly soldiers, though not all armed, were gathered into two overlapping clusters, one in the foreground, the other farther back. They looked remarkably relaxed and cheerful. Some talked among themselves, arms around each other’s shoulders. Others wrestled on the sand or played dice. But kneeling at the center was the mosaic’s focal point and the group’s clear leader: a slight, handsome man with russet hair, who looked out of the wall with a purposeful gaze. Both his hands were clasped on the hilt of his sword, plunged deep into the sand. Knox blinked. No one could study Greco-Roman history without developing a knowledge of mosaic. Yet he’d never seen anything like this.
He had no camera with him except for the one in his mobile phone. He hadn’t even turned it on since Sinai, worried that it would lead Hassan straight to him, but there was no chance of it transmitting a signal this deep underground. He tiptoed carefully into the chamber, photographing the mosaic, the burial caskets, the grave goods scattered on the floor, the inscription. He became so completely absorbed in this work that it was only when he heard a grinding, ripping noise from way behind him that he belatedly remembered the raising of the plinth.
Chapter Eighteen
BASTIAAN AND THREE burly Egyptian security guards kept the disgruntled excavators out of the Macedonian tomb while Mohammed and Mansoor attacked the plinth as they had on the day before, working the tips of their crowbars beneath one end and levering it up. It came more easily this time. They raised it a few inches, just enough for Ibrahim to slide in a hydraulic jack, which they pumped high enough to slide a pallet-trolley beneath. Then they repeated the process at the other end and simply wheeled the plinth back against the wall.
There was a fat black shaft in the floor, just as Ibrahim had glimpsed. They all gathered around. Mansoor directed his flashlight down. Light glinted brightly from five yards below.
“Water,” said Mansoor. “I’ll go first.” He turned to Mohammed. “Tie a noose in a rope. You’ll lower me, yes?”
“Yes,” agreed Mohammed.
KNOX HAD NO TIME FOR FINESSE. He clutched his hand over the bulb of his flashlight to dim it yet allow him just enough light to see what he was doing; then he stripped off his T-shirt so that he could use it to erase his footprints in the dust as he backed out of the chamber and down the steps. But Mansoor was already being lowered on a rope, flashing his light all around him and down the passage, so that Knox had to duck back out of sight. “There’s a corridor!” shouted Mansoor as he splashed into the shallow water and stepped off the stirrup. “I’ll take a look.”
“No!” said Ibrahim. “Wait.”
“But I’ll just—”
“Wait for us.”
The light vanished momentarily. Knox risked another glance, saw the stirrup slithering back up. But then Mansoor shone his flashlight again down the corridor, his frustration evident, giving Knox no chance to escape. Someone else was being lowered now: Gaille, twisting this way and that on the rope. Mansoor turned to help her down. It was Knox’s only chance. He ran along the corridor to his dismantled wall, trying hard not to make waves. But Gaille gave a shriek of alarm. “There’s someone there!” she cried.
Knox stepped through the hole in the wall as Mansoor blazed his flashlight down the corridor. “There’s no one,” he laughed. “How could there be?”
“I could have sworn,” said Gaille.
“Just your imagination,” said Mansoor. “Places like this will do that.”
Knox was only half listening, his heart still hammering, frantically rebuilding his wall from within, taking care to keep as silent as possible. He couldn’t risk his flashlight, so he had to work by feel and what little light reached him from Mansoor, Gaille, and the others as they gathered one by one. But by the time they were all down, his wall was still only three-quarters rebuilt.
“Okay,” said Ibrahim. “Lead on.”
Knox froze. He couldn’t do any more now
