Or at least that was what drove this man, his black cassock dissolving into the darkness of the place, running as fast as he could down the long interior staircase in the Secret Archives of the Vatican, a not-so-secret housing for supposedly secret documents. Those three imposing Vatican halls, and the buildings behind the Apostolic Palace, held documents of critical importance to the history of this small state and of the entire world. Only His Holiness, the pope, could examine them and decide who else could have access. The staff always said that any researcher could consult the Archives, but in Rome, and everywhere else on the planet, it was well known that not everybody was admitted, and those who were could not look at everything. There were many hidden niches in the Secret Archives’ fifty-three miles of shelves.

The clergyman dashed through a secret passageway, holding some papers yellowed with age. A sudden noise, distinct from his own steps, alarmed him. Had it come from upstairs? Downstairs? He froze, perspiration streaming down his face, but all he could hear was the accelerated rhythm of his own breathing. He ran toward his quarters in Vatican City—or Vatican country, rather—because that was what it really was, with its own rules, laws, beliefs, and political system.

Under his weak desk lamp, he scribbled his name—Monsignor Firenzi—on a large envelope into which he thrust the papers, then sealed it. The name of the addressee was illegible in the dim light. His hands, slippery with sweat, struggled to hold on to the envelope. Perspiration clouded his eyes so that he couldn’t make out even his own handwriting. Apparently finished, Monsignor left the room.

The bell at Saint Peter’s Basilica tolled—it was one o’clock in the morning—and then silence reigned again over the dark night. It was cold, but in his haste this servant of God did not even notice. Soon he was out on the walkways that led to Saint Peter’s Square, Bernini’s marvelous ellipse, with its Christian and pagan symbols. Another sound caught Monsignor’s ears. He stopped. Panting and in a cold sweat, he tried to catch his breath. It was surely the sound of steps. Maybe a Swiss Guard on nightly patrol. Monsignor Firenzi quickened his pace, still clutching the envelope. On any other night, he would have been in bed much earlier. As he reached the middle of the plaza, he glanced back and noticed a shadow in the background: not a Swiss Guard, or at least not dressed like one. The dark figure moved closer, but at the same steady pace. Now Monsignor Firenzi was running. He glanced back again, but at this time of night there was no one else but him and the briskly moving shadow.

“Io voglio a te.” The mysterious assailant took out a cell phone and spoke in a foreign tongue, perhaps from some eastern country. Monsignor Firenzi noticed the tattoo near his wrist: a serpent. Seconds later, a black car stopped beside the two men. The dark windows prevented anyone inside but the driver from being seen. Without violence or apparent effort, the man dragged the limp prelate into the car.

Before climbing into the car, the man wiped the surface of the mailbox against which the prelate had fallen after being shot with such precision in the shoulder. Firenzi stared at him while pain racked his body. This is how it feels to be shot, he thought. The man was still wiping off any remaining clues from a few moments before. How ironic, to be wiping away the clues. How ironic. His whole body hurt. Then memories of his home came to him and he blurted out something in Portuguese.

The man got quickly into the car, which cruised slowly so as not to arouse suspicion. They were professionals, they knew what to do and how to do it. The street was quiet again, everything in order. The erasing of the clues was successful, leaving no trace of blood on the mailbox the prelate had leaned on, and where, almost miraculously and unnoticed by his pursuer, he had managed to insert the envelope he was clutching.
