'Believe me, this surprise is worth it,' Gerrard said.

The helicopter kept descending into the murky valley, and immediately Tess realized that some of the flickering bonfires had been arranged in a special pattern. They form a landing pad! she thought.

In the darkness, the helicopter's pilot used the squared-off section of flames to guide him toward a level section in the valley. As the bonfires flickered, the pilot eased the helicopter onto the grass, then shut off the engines.

'And now?' Craig asked.

'Something so sacred that very few have ever seen it,' Gerrard said.

'You worry me. I'm from New York. Mountains, valleys, bonfires? To me, they're like Mars.'

'Then we invite you to look at Mars,' Fulano said. 'I guarantee you'll be impressed. I correct myself. You'll be astonished. Open your mind. Prepare yourself for what will be the greatest memory of your life.'

'Since you're my host,' Craig said, 'I take for granted that I can trust you. I also assume that as a host you feel an obligation to your guests.'

'That goes without saying.'

'All right, then, as long as we've agreed, let's see the surprise that'll be my greatest memory.'

'Follow.'

They stepped from the helicopter.

ELEVEN

Tess felt cloaked with oppressive darkness while in a square that enclosed the helicopter, brilliant bonfires blazed. Their drifting acrid smoke conflicted with the fragrance of the grass and flowers in the night-shrouded valley.

Numerous villagers and farmers, all wearing festive garments, stood next to the flames, holding impressive crosses, woven from flowers and stalks of wheat. As the light flickered over those crosses, Tess faltered, stunned by the memory of what Priscilla Harding had told her. Before Christianity, before the tradition that the cross represented the execution of Christ, a prior tradition had associated the symbol of the cross with the glory of the sun. And now, with chilling certainty, Tess watched the flames reflect off the wheat of the crosses and knew absolutely that those crosses, composed from nature, were devoted to the sun – and to Mithras, the god of the sun.

Fulano took a torch from one of the villagers and gestured for Tess and Craig to walk to his right across the field. Gerrard took another torch and accompanied them as did the two Secret Service agents. But unexpectedly the group became larger, other men joining them from beyond the fires. These newcomers did not wear festive garments. They didn't carry crosses woven from flowers and wheat. What they wore instead was rugged outdoor clothing, and what they carried were automatic weapons.

Beyond the bonfires, the field became disturbingly black, illuminated in patches only by the torches that Fulano and Gerrard held before them. Tess fearfully recalled the torchbearers in the statue that she'd seen in Joseph's bedroom. Her feet and ankles felt cold, the dew on the knee-high grass soaking her sandles and the lower portion of her long skirt. Panic made her want to tug at Craig and run. They might be able to escape in the darkness, she hoped. But despair took charge, making her realize that the guards would hunt them, that the villagers would join in the search, and the odds were that she and Craig would lose their sense of direction, running in circles in this unfamiliar valley, trying to avoid the bonfires until they were captured.

The field began to slope upward. Guided by the torches, she and the rest of the group passed beech trees, veered around boulders, and continued climbing, the dampness making Tess colder. The hill angled higher, and now she smelled the resin of pine trees.

At once the slope leveled off. Grass became rocks. She peered ahead toward where the torches revealed a narrow gap, concealed by bushes, at the base of a cliff. Stepping closer, she saw that the gap was the entrance to a cave. But a few feet into the cave, a rusted iron door formed a barrier.

Fulano handed his torch to a guard, removed a key from his pocket, and released a padlock on the door. With effort, leaning his shoulder against the door, he shoved it open, its hinges creaking. The night became eerily silent, the only sound the crackling torches and Fulano's footsteps as he disappeared beyond the door. Five seconds later, the silence was broken by the sound of something being cranked, then the sputter of an engine, then a roar as the engine came to life. The interior of the cave was abruptly illuminated by a dim bulb attached to the ceiling, and Tess saw that the engine was a kerosene-powered generator.

Someone nudged her back. Turning, Tess blinked in surprise at Hugh Kelly, who must have joined them during the trek up the slope. Where had he been? What had he been doing? Like the guards, he too wore outdoor clothing.

'Go in,' he said. 'You'll find shoes and a jacket. The cave can be slippery. It's also cold.'

'I brought my sneakers,' Tess said. She took them from her purse and pulled them on, her feet at last secure.

No matter, she trembled. The torches were set on the ground, twisted among the rocks, and extinguished. When she and Craig entered the cave, followed by Gerrard, Kelly and the guards, she noticed woolen coats opposite the generator and put one on, buttoning it. Despite its insulation, she continued to tremble.

The narrow passage was barely head-tall. Proceeding, she stopped ten yards ahead just beyond a curve, frowning at another iron door.

While Fulano unlocked it, Hugh Kelly shut and locked the first door.

That's it, she thought. We're finished.

'Don't look so nervous.' Despite the roar of the generator, Fulano's voice reverberated off the damp limestone walls. 'That locked door is strictly for security precautions. After all, we're here at night, and remember, you're not the only ones at risk. Alan and I are attractive targets for assassins. I trust the villagers, but the darkness could very well hide enemies who may have kept track of our movements and would like nothing better than to catch us alone in this isolated area. Three guards have stayed outside to make sure that no one attacks us when we leave. As you may have noticed, Alan's Secret Service agents don't look happy about this trip.'

'I did notice.' Tess remained convinced that the guards cared more about Craig and herself than they did about Gerrard and Fulano. All the same, she pretended to follow his logic. 'But what if something goes wrong outside? What if your guards are overpowered?'

'We try to contact them with walkie-talkies. If they don't respond,' Gerrard explained and gestured off-handedly, 'we use a different exit.'

'You've thought of everything,' Craig said.

'We try to.' Fulano nudged the farther door, forcing it open, its hinges screeching, its iron bottom scraping against rock. 'And now the surprise.'

'One of the greatest wonders in the world,' Gerrard said. 'Few people have seen it. Only those who deserve to, who have the capacity to appreciate it, who care about the planet, about its soul, and you, Tess, have the right. Because you do care. With a passion. You've proven that in your articles.'

'So now' – Fulano shoved the door completely open – 'you're about to see a mystery. Perhaps the greatest mystery. Something so sacred that after you see it, you'll never be the same.'

'I can't imagine what-'

'No,' Gerrard said. 'Don't imagine. Don't anticipate. Just witness it. Just stand back and appreciate. You're about to be changed.'

'The way my life has been going, I'm due for a change. For the better, I hope.'

'For the better,' Fulano said. 'No question. You have my word. Absolutely.'

Tess followed them through the door, clutched Craig's hand, and felt the guards behind her. Fulano paused to lock the second entrance.
