Outside the walls of the chapel, of course, the media watched and waited, speculating as to which of the cardinals would become the ruler of one billion Catholics worldwide. Conclaves created an intense, politically charged atmosphere, and over the centuries they had turned deadly: poisonings, fist fights, and even murder had erupted within the sacred walls. Ancient history, Mortati thought. Tonight’s conclave will be unified, blissful, and above all… brief.

Or at least that had been his speculation.

Now, however, an unexpected development had emerged. Mystifyingly, four cardinals were absent from the chapel. Mortati knew that all the exits to Vatican City were guarded, and the missing cardinals could not have gone far, but still, with less than an hour before opening prayer, he was feeling disconcerted. After all, the four missing men were no ordinary cardinals. They were the cardinals.

The chosen four.

As overseer of the conclave, Mortati had already sent word through the proper channels to the Swiss Guard alerting them to the cardinals’ absence. He had yet to hear back. Other cardinals had now noticed the puzzling absence. The anxious whispers had begun. Of all cardinals, these four should be on time! Cardinal Mortati was starting to fear it might be a long evening after all.

He had no idea.

The Vatican’s helipad, for reasons of safety and noise control, is located in the northwest tip of Vatican City, as far from St. Peter’s Basilica as possible.

"Terra firma," the pilot announced as they touched down. He exited and opened the sliding door for Langdon and Vittoria.

Langdon descended from the craft and turned to help Vittoria, but she had already dropped effortlessly to the ground. Every muscle in her body seemed tuned to one objective—finding the antimatter before it left a horrific legacy.

After stretching a reflective sun tarp across the cockpit window, the pilot ushered them to an oversized electric golf cart waiting near the helipad. The cart whisked them silently alongside the country’s western border—a fifty-foot-tall cement bulwark thick enough to ward off attacks even by tanks. Lining the interior of the wall, posted at fifty-meter intervals, Swiss Guards stood at attention, surveying the interior of the grounds. The cart turned sharply right onto Via della Osservatorio. Signs pointed in all directions:

Palazzio Governatorio

Collegio Ethiopiana

Basilica San Pietro

Capella Sistina

They accelerated up the manicured road past a squat building marked Radio Vaticana. This, Langdon realized to his amazement, was the hub of the world’s most listened-to radio programming—Radio Vaticana—spreading the word of God to millions of listeners around the globe.

"Attenzione," the pilot said, turning sharply into a rotary.

As the cart wound round, Langdon could barely believe the sight now coming into view. Giardini Vaticani, he thought. The heart of Vatican City. Directly ahead rose the rear of St. Peter’s Basilica, a view, Langdon realized, most people never saw. To the right loomed the Palace of the Tribunal, the lush papal residence rivaled only by Versailles in its baroque embellishment. The severe-looking Governatorato building was now behind them, housing Vatican City’s administration. And up ahead on the left, the massive rectangular edifice of the Vatican Museum. Langdon knew there would be no time for a museum visit this trip.

"Where is everyone?" Vittoria asked, surveying the deserted lawns and walkways.

The guard checked his black, military-style chronograph—an odd anachronism beneath his puffy sleeve. "The cardinals are convened in the Sistine Chapel. Conclave begins in a little under an hour."

Langdon nodded, vaguely recalling that before conclave the cardinals spent two hours inside the Sistine Chapel in quiet reflection and visitations with their fellow cardinals from around the globe. The time was meant to renew old friendships among the cardinals and facilitate a less heated election process. "And the rest of the residents and staff?"

"Banned from the city for secrecy and security until the conclave concludes."

"And when does it conclude?"

The guard shrugged. "God only knows." The words sounded oddly literal.
