"Mr. Langdon, I am due in the Sistine Chapel in four minutes. The archives are across Vatican City."

"You’re serious aren’t you?" Vittoria interrupted, staring deep into Langdon’s eyes, seeming to sense his earnestness.

"Hardly a joking time," Langdon said.

"Father," Vittoria said, turning to the camerlegno, "if there’s a chance… any at all of finding where these killings are going to happen, we could stake out the locations and—"

"But the archives?" the camerlegno insisted. "How could they possibly contain any clue?"

"Explaining it," Langdon said, "will take longer than you’ve got. But if I’m right, we can use the information to catch the Hassassin."

The camerlegno looked as though he wanted to believe but somehow could not. "Christianity’s most sacred codices are in that archive. Treasures I myself am not privileged enough to see."

"I am aware of that."

"Access is permitted only by written decree of the curator and the Board of Vatican Librarians."

"Or," Langdon declared, "by papal mandate. It says so in every rejection letter your curator ever sent me."

The camerlegno nodded.

"Not to be rude," Langdon urged, "but if I’m not mistaken a papal mandate comes from this office. As far as I can tell, tonight you hold the trust of his station. Considering the circumstances…"

The camerlegno pulled a pocket watch from his cassock and looked at it. "Mr. Langdon, I am prepared to give my life tonight, quite literally, to save this church."

Langdon sensed nothing but truth in the man’s eyes.

"This document," the camerlegno said, "do you truly believe it is here? And that it can help us locate these four churches?"

"I would not have made countless solicitations for access if I were not convinced. Italy is a bit far to come on a lark when you make a teacher’s salary. The document you have is an ancient—"

"Please," the camerlegno interrupted. "Forgive me. My mind cannot process any more details at the moment. Do you know where the secret archives are located?"

Langdon felt a rush of excitement. "Just behind the Santa Ana Gate."

"Impressive. Most scholars believe it is through the secret door behind St. Peter’s Throne."

"No. That would be the Archivio della Reverenda di Fabbrica di S. Pietro. A common misconception."

"A librarian docent accompanies every entrant at all times. Tonight, the docents are gone. What you are requesting is carte blanche access. Not even our cardinals enter alone."

"I will treat your treasures with the utmost respect and care. Your librarians will find not a trace that I was there."

Overhead the bells of St. Peter’s began to toll. The camerlegno checked his pocket watch. "I must go." He paused a taut moment and looked up at Langdon. "I will have a Swiss Guard meet you at the archives. I am giving you my trust, Mr. Langdon. Go now."

Langdon was speechless.

The young priest now seemed to possess an eerie poise. Reaching over, he squeezed Langdon’s shoulder with surprising strength. "I want you to find what you are looking for. And find it quickly."

The Secret Vatican Archives are located at the far end of the Borgia Courtyard directly up a hill from the Gate of Santa Ana. They contain over 20,000 volumes and are rumored to hold such treasures as Leonardo da Vinci’s missing diaries and even unpublished books of the Holy Bible.

Langdon strode powerfully up the deserted Via della Fondamenta toward the archives, his mind barely able to accept that he was about to be granted access. Vittoria was at his side, keeping pace effortlessly. Her almond-scented hair tossed lightly in the breeze, and Langdon breathed it in. He felt his thoughts straying and reeled himself back.

Vittoria said, "You going to tell me what we’re looking for?"

"A little book written by a guy named Galileo."

She sounded surprised. "You don’t mess around. What’s in it?"

"It is supposed to contain something called il segno."

"The sign?"

"Sign, clue, signal… depends on your translation."

"Sign to what?"

Langdon picked up the pace. "A secret location. Galileo’s Illuminati needed to protect themselves from the Vatican, so they founded an ultrasecret Illuminati meeting place here in Rome. They called it The Church of Illumination."

"Pretty bold calling a satanic lair a church."

Langdon shook his head. "Galileo’s Illuminati were not the least bit satanic. They were scientists who revered enlightenment. Their meeting place was simply where they could safely congregate and discuss topics forbidden by the Vatican. Although we know the secret lair existed, to this day nobody has ever located it."

"Sounds like the Illuminati know how to keep a secret."

"Absolutely. In fact, they never revealed the location of their hideaway to anyone outside the brotherhood. This secrecy protected them, but it also posed a problem when it came to recruiting new members."

"They couldn’t grow if they couldn’t advertise," Vittoria said, her legs and mind keeping perfect pace.
