The voice emanating from the camerlegno's speaker phone was metallic and cold, laced with arrogance. Everyone in the room listened.

"I am a messenger of an ancient brotherhood," the voice announced in an alien cadence. "A brotherhood you have wronged for centuries. I am a messenger of the Illuminati."

Langdon tried to place the accent. Middle Eastern, perhaps?

"What do you want?" the camerlegno demanded.

"I represent men of science. Men who like yourselves are searching for the answers. Answers to man's destiny, his purpose, his creator."

Langdon felt his muscles tighten, the last shreds of doubt withering away. For an instant he felt the familiar collision of thrill, privilege, and dead fear that he had experienced when he first saw the ambigram this morning.

"Whoever you are," the camerlegno said, "I --"

"Silenzio. You will do better to listen. For two millennia your church has dominated the quest for truth. You have crushed your opposition with lies and prophesies of doom. You have manipulated the truth to serve your needs, murdering those whose discoveries did not serve your politics. Are you surprised you are the target of enlightened men from around the globe?"

"Blackmail?" The caller laughed. "This is not blackmail. We have no demands. The abolition of the Vatican is nonnegotiable. We have waited four hundred years for this day. At midnight, your city will be destroyed. There is nothing you can do."

"Enlightened men do not resort to blackmail to further their causes."

Olivetti stormed toward the speaker phone. "Access to this city is impossible! You could not possibly have planted explosives in here!"

"You speak with the ignorant devotion of a Swiss Guard. Perhaps even an officer? Surely you are aware that for centuries the Illuminati have infiltrated elitist organizations across the globe. Do you really believe the Vatican is immune?"

Jesus, Langdon thought, they've got someone on the inside. It was no secret that infiltration was the Illuminati trademark of power. They had infiltrated the Masons, major banking networks, government bodies. In fact, Churchill had once told reporters that if English spies had infiltrated the Nazis to the degree the Illuminati had infiltrated English Parliament, the war would have been over in one month.

"Our assets?" Olivetti scowled. "What do you mean?"

"What the hell are you talk --" Olivetti stopped short, his eyes rocketing wide as though he'd just been punched in the gut.

"A transparent bluff," Olivetti snapped. "Your influence cannot possibly extend so far."

"What's going on?" the camerlegno said, looking bewildered.

"Why? Because your Swiss Guards are vigilant? Because they watch every corner of your private world? How about the Swiss Guards themselves? Are they not men? Do you truly believe they stake their lives on a fable about a man who walks on water? Ask yourself how else the canister could have entered your city. Or how four of your most precious assets could have disappeared this afternoon."

"Light dawns," the caller said. "Shall I read their names?"

"One, two, three, four. You haven't missed them by now?"

The caller laughed. "Your officer has not yet informed you? How sinful. No surprise. Such pride. I imagine the disgrace of telling you the truth… that four cardinals he had sworn to protect seem to have disappeared…"

The camerlegno turned to Olivetti, his green eyes demanding an explanation.

"Our inventory," the caller said, "you will find quite convincing. There is Cardinal Lamassé from Paris, Cardinal Guidera from Barcelona, Cardinal Ebner from Frankfurt…"

Olivetti erupted. "Where did you get this information!"

"Enjoying the grounds?" The calm departed from the camerlegno's voice. "They were due in the chapel over an hour ago!"

"Camerlegno," the caller gloated, "ask your commander if all your cardinals are present in the Sistine Chapel."

Langdon shot Vittoria a look of amazement. Missing cardinals? So that's what they were looking for downstairs?

"Signore," Olivetti whispered in the camerlegno's ear, "it is true that four of our cardinals have not yet reported to the Sistine Chapel, but there is no need for alarm. Every one of them checked into the residence hall this morning, so we know they are safely inside Vatican City. You yourself had tea with them only hours ago. They are simply late for the fellowship preceding conclave. We are searching, but I'm sure they just lost track of time and are still out enjoying the grounds."

Olivetti seemed to shrink smaller and smaller after each name was read.

The caller paused, as though taking special pleasure in the final name. "And from Italy… Cardinal Baggia."

Langdon had read enough about modern papal elections to understand the look of desperation on the camerlegno's face. Although technically any cardinal under eighty years old could become Pope, only a very few had the respect necessary to command a two-thirds majority in the ferociously partisan balloting procedure. They were known as the preferiti. And they were all gone.

Sweat dripped from the camerlegno's brow. "What do you intend with these men?"

The camerlegno loosened like a tall ship that had just run sheets first into a dead calm. His frock billowed, and he collapsed in his chair."I preferiti," he whispered. "The four favorites… including Baggia… the most likely successor as Supreme Pontiff… how is it possible?"

"What do you think I intend? I am a descendant of the Hassassin."

Langdon felt a shiver. He knew the name well. The church had made some deadly enemies through the years -- the Hassassin, the Knights Templar, armies that had been either hunted by the Vatican or betrayed by them.

The camerlegno was silent.

"Forget your four cardinals. They are lost to you. Be assured their deaths will be remembered though… by millions. Every martyr's dream. I will make them media luminaries. One by one. By midnight the Illuminati will have everyone's attention. Why change the world if the world is not watching? Public killings have an intoxicating horror about them, don't they? You proved that long ago… the inquisition, the torture of the Knights Templar, the Crusades." He paused. "And of course, la purga."

"La purga,"Langdon heard himself say. "Sixteen sixty-eight. The church branded four Illuminati scientists with the symbol of the cross. To purge their sins."

"Do you not recallla purga?" the caller asked. "Of course not, you are a child. Priests are poor historians, anyway. Perhaps because their history shames them?"

"Who is speaking?" the voice demanded, sounding more intrigued than concerned. "Who else is there?"

"Let the cardinals go," the camerlegno said. "Isn't threatening to destroy the City of God enough?"

"Yes. So we shall do the same. Quid pro quo. Consider it symbolic retribution for our slain brothers. Your four cardinals will die, one every hour starting at eight. By midnight the whole world will be enthralled."

"Superb," the voice replied. "I am pleased there are still those alive who remember the crimes against us."

Langdon felt shaky. "My name is not important," he said, trying to keep his voice from wavering. Speaking to a living Illuminatus was disorienting for him… like speaking to George Washington. "I am an academic who has studied the history of your brotherhood."

"Most of us think you are dead."

"A misconception the brotherhood has worked hard to promote. What else do you know ofla purga?"

Langdon moved toward the phone. "You actually intend to brand and kill these four men?"

Langdon hesitated. What else do I know? That this whole situation is insanity, that's what I know! "After the brandings, the scientists were murdered, and their bodies were dropped in public locations around Rome as a warning to other scientists not to join the Illuminati."

"What are you saying?" Langdon asked. "That you are going to brand and kill these men in public?"

"Very good. Although it depends what you consider public. I realize not many people go to church anymore."

"History repeats itself, does it not? Of course, we will be more elegant and bold than the church was. They killed privately, dropping bodies when no one was looking. It seems so cowardly."

"A gesture of kindness. Enabling God to command their souls to heaven more expeditiously. It seems only right. Of course the press will enjoy it too, I imagine."

Langdon did a double take. "You're going to kill them in churches?"

"Bluffing? We move among your Swiss Guard like ghosts, remove four of your cardinals from within your walls, plant a deadly explosive at the heart of your most sacred shrine, and you think this is a bluff? As the killings occur and the victims are found, the media will swarm. By midnight the world will know the Illuminati cause."

"You're bluffing," Olivetti said, the cool back in his voice. "You cannot kill a man in a church and expect to get away with it."

"In ninety minutes it begins," the caller said with a note of finality. "One an hour. A mathematical progression of death. Now I must go."

"And if we stake guards in every church?" Olivetti said.

The caller laughed. "I fear the prolific nature of your religion will make that a trying task. Have you not counted lately? There are over four hundred Catholic churches in Rome. Cathedrals, chapels, tabernacles, abbeys, monasteries, convents, parochial schools…"

"Wait!" Langdon demanded. "Tell me about the brands you intend to use on these men."

Olivetti's face remained hard.

Langdon felt light-headed. He knew exactly what the man was claiming. Langdon pictured the brand on Leonardo Vetra's chest. Illuminati folklore spoke of five brands in all. Four brands are left, Langdon thought, and four missing cardinals.

"I am sworn," the camerlegno said, "to bring a new Pope tonight. Sworn by God."

The killer sounded amused. "I suspect you know what the brands will be already. Or perhaps you are a skeptic? You will see them soon enough. Proof the ancient legends are true."

The camerlegno looked sincerely sad. "You are misguided. A church is more than mortar and stone. You cannot simply erase two thousand years of faith…any faith. You cannot crush faith simply by removing its earthly manifestations. The Catholic Church will continue with or without Vatican City."

Silence hung.

"Camerlegno," the caller said, "the world does not need a new Pope. After midnight he will have nothing to rule over but a pile of rubble. The Catholic Church is finished. Your run on earth is done."

"How young are you? The Vatican is a fortress because the Catholic Church holds half of its equity inside its walls -- rare paintings, sculpture, devalued jewels, priceless books… then there is the gold bullion and the real estate deeds inside the Vatican Bank vaults. Inside estimates put the raw value of Vatican City at 48.5 billion dollars. Quite a nest egg you're sitting on. Tomorrow it will be ash. Liquidated assets as it were. You will be bankrupt. Not even men of cloth can work for nothing."

"Men of God live in a dangerous world," the camerlegno said.

"A noble lie. But a lie all the same. We both know the truth. Tell me, why is Vatican City a walled citadel?"

The camerlegno sighed heavily. "Faith, not money, is the backbone of this church."

"Do not insult us both."

"More lies," the caller said. "Last year you spent 183 million dollars trying to support your struggling dioceses worldwide. Church attendance is at an all-time low-down forty-six percent in the last decade. Donations are half what they were only seven years ago. Fewer and fewer men are entering the seminary. Although you will not admit it, your church is dying. Consider this a chance to go out with a bang."

Olivetti stepped forward. He seemed less combative now, as if he now sensed the reality facing him. He looked like a man searching for an out. Any out. "And what if some of that bullion went to fund your cause?"

"We have money."

"As do we. More than you can fathom."

The accuracy of the statement seemed to be reflected in Olivetti's and the camerlegno's shell-shocked looks. Langdon wasn't sure what was more amazing, that the Catholic Church had that kind of money, or that the Illuminati somehow knew about it.

The caller sneered. "Leonardo Vetra was a man of faith, and yet I saw fear in his eyes last night. A fear I removed."

The camerlegno was silent for a long time. "They are men of faith," he finally said. "They do not fear death."

Langdon flashed on the alleged Illuminati fortunes, the ancient wealth of the Bavarian stone masons, the Rothschilds, the Bilderbergers, the legendary Illuminati Diamond.

Vittoria, who had been silent, was suddenly airborne, her body taut with hatred."Asino! He was my father!"

A cackle echoed from the speaker. "Your father? What is this? Vetra has a daughter? You should know your father whimpered like a child at the end. Pitiful really. A pathetic man."

"They are virgin sacrifices." The caller laughed. "Tell me, do you think they arereally virgins? Will the little lambs squeal when they die? Sacrifici vergini nell" altare di scienza."

The caller laughed coarsely. "A woman of spirit. I am aroused. Perhaps before this night is over, I will find you. And when I do…"

"I preferiti," the camerlegno said, changing the subject. His voice was pleading. "Spare them. They are old. They --"

Vittoria reeled as if knocked backward by the words. Langdon reached for her, but she regained her balance and fixed her dark eyes on the phone. "I swear on my life, before this night is over, I will find you." Her voice sharpened like a laser. "And when I do…"

The words hung like a blade. Then he was gone.
