"Exactly," Langdon said, quickly turning up Via Sentinel toward the archives. "The pieces blended into the sea of religious artwork all over Rome. By donating the artwork anonymously to specific churches and then using their political influence, the brotherhood facilitated placement of these four pieces in carefully chosen churches in Rome. Each piece of course was a marker… subtly pointing to the next church… where the next marker awaited. It functioned as a trail of clues disguised as religious art. If an Illuminati candidate could find the first church and the marker for Earth, he could follow it to Air… and then to Fire… and then to Water… and finally to the Church of Illumination."
Vittoria was looking less and less clear. "And this has something to do with catching the Illuminati assassin?"
Langdon smiled as he played his ace. "Oh, yes. The Illuminati called these four churches by a very special name.
Vittoria frowned. "I’m sorry, that means noth—" She stopped short. "
Langdon gave her a smile. "Four cardinals. Four churches. The four altars of science."
She looked stunned. "You’re saying the four churches where the cardinals will be sacrificed are the
"I believe so, yes."
"But why would the killer have given us that clue?"
"Why not?" Langdon replied. "Very few historians know about these sculptures. Even fewer believe they exist. And their locations have remained secret for four hundred years. No doubt the Illuminati trusted the secret for another five hours. Besides, the Illuminati don’t
Langdon feared the Illuminati unveiling would have a special symmetry to it that he had not yet mentioned.
Langdon turned up the brick pathway before the archive building. Ghastly images thrashed in his mind. The overall Illuminati plot was starting to reveal its patient grandeur. The brotherhood had vowed to stay silent as long as it took, amassing enough influence and power that they could resurface without fear, make their stand, fight their cause in broad daylight. The Illuminati were no longer about hiding. They were about flaunting their power, confirming the conspiratorial myths as fact. Tonight was a global publicity stunt.
Vittoria said, "Here comes our escort." Langdon looked up to see a Swiss Guard hurrying across an adjacent lawn toward the front door.
When the guard saw them, he stopped in his tracks. He stared at them, as though he thought he was hallucinating. Without a word he turned away and pulled out his walkie-talkie. Apparently incredulous at what he was being asked to do, the guard spoke urgently to the person on the other end. The angry bark coming back was indecipherable to Langdon, but its message was clear. The guard slumped, put away the walkie-talkie, and turned to them with a look of discontent.
Not a word was spoken as the guard guided them into the building. They passed through four steel doors, two passkey entries, down a long stairwell, and into a foyer with two combination keypads. Passing through a high-tech series of electronic gates, they arrived at the end of a long hallway outside a set of wide oak double doors. The guard stopped, looked them over again and, mumbling under his breath, walked to a metal box on the wall. He unlocked it, reached inside, and pressed a code. The doors before them buzzed, and the deadbolt fell open.
The guard turned, speaking to them for the first time. "The archives are beyond that door. I have been instructed to escort you this far and return for briefing on another matter."
"You’re leaving?" Vittoria demanded.
"Swiss Guards are not cleared for access to the Secret Archives. You are here only because my commander received a direct order from the camerlegno."
"But how do we get
