DHOFAR MOUNTAINS

SAFIA STAREDout the window as the truck wound up a switchback through the mountainous hills. After they left the highway, asphalt had given way to gravel, which in turn disintegrated into a rutted red dirt path. They proceeded slowly, cautious of the deep gorge that shouldered the road to the left.

Below, the valley flowed away in deepening shades of lush green, disappearing into shadows near the bottom as the sun set to the west. A scatter of baobab trees dotted the slope, monstrous trees with tangled, rooted trunks that seemed more prehistoric than specimens of the modern world. Everywhere the land rolled in shades of emerald, striped in shadows. A waterfall glistened between two distant hills, its cataracts sparkling in the last rays of the sun.

If Safia squinted, she could almost imagine she was back in England.

All the lushness of the high country was due to the annual monsoon winds, the khareef, that swept the foothills and mountains in a continual misty drizzle from June through September. Even now, as the sun set, a steady wind had begun to blow, buffeting the truck. The sky overhead had darkened to slate gray, canopied with frothy clouds that brushed the higher hills.

The radio had been tuned to a local news channel during the ride up here. Cassandra had been listening for reports on the ongoing salvage operation on the Shabab Oman. Still, no survivors had been found, and the seas were again kicking up with the approach of a new storm system. But what dominated the weather reports was news of the fierce sandstorm continuing its sweep south across Saudi Arabia, heading like a freight train for the desert of Oman, leaving a swath of destruction.

The wild weather matched Safia’s mood: dark, threatening, unpredictable. She felt a force building inside her, below her breastbone, a tempest in a bottle. She remained tense, tingling. It reminded her of an impending anxiety attack, but now there was no fear, only determined certainty. She had nothing, so could lose nothing. She remembered her years in London. It had been the same. She had sought comfort by becoming nothing, cutting herself off, isolating herself. But now she had truly succeeded. She was empty, left with only one purpose: to stop Cassandra. And that was enough.

Cassandra remained lost in her own thoughts, only occasionally leaning forward to speak in hushed tones to John Kane up front. Her cell phone had rung a few minutes ago. She had answered it tersely, turning slightly away, speaking in a whisper. Safia heard Painter’s name. She had tried to eavesdrop, but the woman kept her voice too low, blocked by the babble of the radio. Then she had hung up, made two other calls, and sunk into a palpably tense silence. Anger seemed to radiate in waves from the woman.

Since then, Safia kept her attention on the countryside, searching for places where she might hide, mapping the terrain in her head, just in case.

After another ten minutes of slow trekking, a larger hill appeared, its top still bathed in light. The golden bell of a short tower glinted in the sun.

Safia straightened. Job’s tomb.

“Is that the place?” Cassandra stirred, eyes still narrowed.

Safia nodded, sensing that now was not the time to provoke her captor.

The SUV coasted down a final slope, circled the base of the mount, and then began a long climb toward the top, crawling up a switchback. A group of camels lounged beside the road as their vehicle neared the hilltop tomb. The beasts were all couched for a rest, kneeling down atop their knobby knees. A few men sat in the shadow of a baobab, tribesmen from the hills. The eyes of both camels and men followed the passage of the three trucks.

After a last switchback, the walled tomb complex appeared, consisting of a small beige building, a tiny whitewashed mosque, and a handsome garden courtyard of native shrubs and flowers. Parking was merely an open stretch of dirt in front, presently empty because of the lateness of the day.

As before, Kane settled the truck to a stop, then came around to open Safia’s door. She climbed out, stretching a kink from her neck. Cassandra joined them as the other two SUVs parked and the men unloaded. They were all dressed in civilian clothes: khakis and Levi’s, short-sleeved shirts, polos. But all the men wore matching windbreakers with the logo for Sunseeker Tours, all a size too big, hiding their holstered weapons. They quickly dispersed into a loose cordon near the road, feigning interest in the gardens or walls. A pair had binoculars and scanned the immediate area, turning in a slow circle.

Except for the road leading here, the remaining approaches were steep, almost vertical cliff faces. It would not be easy to flee on foot.

John Kane went among his men, nodding, bowing his head in last-minute instructions, then returned. “Where first?”

Safia motioned vaguely to the mosque and vault. From one tomb to another. She led the way through the opening in the wall.

“Place looks deserted,” Kane commented.

“There must be a caretaker somewhere about,” Safia said, and pointed to the steel chain that lay loose beside the entrance. No one had locked the place.

Cassandra signaled to two men. “Search the grounds.”

Obeying, the pair took off.

Cassandra led the way after them. Safia followed with Kane at her side. They entered the courtyard between the mosque and small beige vault. The only other feature of the complex was a small set of ancient ruins near the back, neighboring the tomb. An ancient prayer room, supposedly all that was left of Job’s original home.

Closer by, the door to the tomb lay open, unlocked like the gate.

Safia stared toward the doorway. “This may take some time. I don’t have the slightest idea where to begin to look for the next clue.”

“If it takes all night, then it takes all night.”

“We’re staying here?” Safia could not keep the surprise from her voice.

Cassandra wore a hard-edged expression. “For as long as it takes.”

Safia swept the courtyard with her gaze. She prayed the caretaker had been careless in locking the place up and had already left. She feared hearing a gunshot somewhere out there, marking his death. And what if other pilgrims came later? How many more would die?

Safia felt conflicted. The sooner Cassandra had what she wanted, the less chance that other innocent folk would die. But that meant helping her. Something she was loath to do.

With no other choice, she crossed the grounds and entered the crypt. She had an inkling of what needed to be found-but not where it might be hidden.

She stood a moment in the entryway. The crypt here was smaller than Nabi Imran’s tomb, a perfect square. The walls were painted white, the floor green. A pair of red Persian prayer rugs flanked the grave mound, which again was draped in silk shawls imprinted with passages from the Koran. Beneath the cloths was the bare dirt in which Job’s body was said to have been buried.

Safia made a slow circle around the mound. There was no marble headstone as there had been at Imran’s tomb, only a scattering of clay incense burners, scorched black from frequent use, and a small tray for visitors to leave gifts of coins. The room was otherwise unadorned, with the exception of a wall chart listing the names of the prophets: Moses, Abraham, Job, Jesus, and Muhammad. Safia hoped they wouldn’t need to track all these men’s tombs on the road to Ubar. She ended back at the entrance, none the wiser.

Cassandra spoke at the door. “What about that iron heart? Can we use it here?” As before, she had brought the silver case and had set it outside the door.

Safia shook her head, sensing that the heart would not be significant here. She exited the chamber, slipping between Cassandra and Kane.
