he crisp April air whipped through the open window of the Citroën ZX as it skimmed south past the Opera House and crossed Place Vendôme. In the passenger seat, Robert Langdon felt the city tear past him as he tried to clear his thoughts. His quick shower and shave had left him looking reasonably presentable but had done little to ease his anxiety. The frightening image of the curator's body remained locked in his mind.!!!Jacques Saunière is dead.

Langdon could not help but feel a deep sense of loss at the curator's death. Despite Saunière's reputation for being reclusive, his recognition for dedication to the arts made him an easy man to revere. His books on the secret codes hidden in the paintings of Poussin and Teniers were some of Langdon's favorite classroom texts. Tonight's meeting had been one Langdon was very much looking forward to, and he was disappointed when the curator had not shown.

Again the image of the curator's body flashed in his mind. Jacques Saunière did that to himself? Langdon turned and looked out the window, forcing the picture from his mind.

Outside, the city was just now winding down—street vendors wheeling carts of candied amandes, waiters carrying bags of garbage to the curb, a pair of late night lovers cuddling to stay warm in a breeze scented with jasmine blossom. The Citroën navigated the chaos with authority, its dissonant two-tone siren parting the traffic like a knife.

"Le capitaine was pleased to discover you were still in Paris tonight," the agent said, speaking for the first time since they'd left the hotel. "A fortunate coincidence."

Langdon was feeling anything but fortunate, and coincidence was a concept he did not entirely trust. As someone who had spent his life exploring the hidden interconnectivity of disparate emblems and ideologies, Langdon viewed the world as a web of profoundly intertwined histories and events. The connections may be invisible, he often preached to his symbology classes at Harvard,!!!but they are always there, buried just beneath the surface.

"I assume," Langdon said, "that the American University of Paris told you where I was staying?"

The driver shook his head. "Interpol."

Interpol, Langdon thought. Of course. He had forgotten that the seemingly innocuous request of all European hotels to see a passport at check-in was more than a quaint formality—it was the law. On any given night, all across Europe, Interpol officials could pinpoint exactly who was sleeping where. Finding Langdon at the Ritz had probably taken all of five seconds.

As the Citroën accelerated southward across the city, the illuminated profile of the Eiffel Tower appeared, shooting skyward in the distance to the right. Seeing it, Langdon thought of Vittoria, recalling their playful promise a year ago that every six months they would meet again at a different romantic spot on the globe. The Eiffel Tower, Langdon suspected, would have made their list. Sadly, he last kissed Vittoria in a noisy airport in Rome more than a year ago.

"Did you mount her?" the agent asked, looking over.

Langdon glanced up, certain he had misunderstood. "I beg your pardon?"

"She is lovely, no?" The agent motioned through the windshield toward the Eiffel Tower. "Have you mounted her?"

Langdon rolled his eyes. "No, I haven't climbed the tower."

"She is the symbol of France. I think she is perfect."

Langdon nodded absently. Symbologists often remarked that France—a country renowned for machismo, womanizing, and diminutive insecure leaders like Napoleon and Pepin the Short—could not have chosen a more apt national emblem than a thousand-foot phallus.

When they reached the intersection at Rue de Rivoli, the traffic light was red, but the Citroën didn't slow. The agent gunned the sedan across the junction and sped onto a wooded section of Rue Castiglione, which served as the northern entrance to the famed Tuileries Gardens—Paris's own version of Central Park. Most tourists mistranslated Jardins des Tuileries as relating to the thousands of tulips that bloomed here, but Tuileries was actually a literal reference to something far less romantic. This park had once been an enormous, polluted excavation pit from which Parisian contractors mined clay to manufacture the city's famous red roofing tiles—or tuiles.

As they entered the deserted park, the agent reached under the dash and turned off the blaring siren. Langdon exhaled, savoring the sudden quiet. Outside the car, the pale wash of halogen headlights skimmed over the crushed gravel parkway, the rugged whir of the tires intoning a hypnotic rhythm. Langdon had always considered the Tuileries to be sacred ground. These were the gardens in which Claude Monet had experimented with form and color, and literally inspired the birth of the Impressionist movement. Tonight, however, this place held a strange aura of foreboding.

The Citroën swerved left now, angling west down the park's central boulevard. Curling around a circular pond, the driver cut across a desolate avenue out into a wide quadrangle beyond. Langdon could now see the end of the Tuileries Gardens, marked by a giant stone archway.

Arc du Carrousel.

Despite the orgiastic rituals once held at the Arc du Carrousel, art aficionados revered this place for another reason entirely. From the esplanade at the end of the Tuileries, four of the finest art museums in the world could be seen… one at each point of the compass.

Out the right-hand window, south across the Seine and Quai Voltaire, Langdon could see the dramatically lit facade of the old train station—now the esteemed Musée d'Orsay. Glancing left, he could make out the top of the ultramodern Pompidou Center, which housed the Museum of Modern Art. Behind him to the west, Langdon knew the ancient obelisk of Ramses rose above the trees, marking the Musée du Jeu de Paume.

But it was straight ahead, to the east, through the archway, that Langdon could now see the monolithic Renaissance palace that had become the most famous art museum in the world.

Musée du Louvre.

Langdon felt a familiar tinge of wonder as his eyes made a futile attempt to absorb the entire mass of the edifice. Across a staggeringly expansive plaza, the imposing facade of the Louvre rose like a citadel against the Paris sky. Shaped like an enormous horseshoe, the Louvre was the longest building in Europe, stretching farther than three Eiffel Towers laid end to end. Not even the million square feet of open plaza between the museum wings could challenge the majesty of the facade's breadth. Langdon had once walked the Louvre's entire perimeter, an astonishing three-mile journey.

Despite the estimated five days it would take a visitor to properly appreciate the 65,300 pieces of art in this building, most tourists chose an abbreviated experience Langdon referred to as "Louvre Lite"—a full sprint through the museum to see the three most famous objects: the Mona Lisa, Venus de Milo, and Winged Victory. Art Buchwald had once boasted he'd seen all three masterpieces in five minutes and fifty-six seconds.

The driver pulled out a handheld walkie-talkie and spoke in rapid-fire French.!!!"Monsieur Langdon est arrivé. Deux minutes."

An indecipherable confirmation came crackling back.

The agent stowed the device, turning now to Langdon. "You will meet the capitaine at the main entrance."

The driver ignored the signs prohibiting auto traffic on the plaza, revved the engine, and gunned the Citroën up over the curb. The Louvre's main entrance was visible now, rising boldly in the distance, encircled by seven triangular pools from which spouted illuminated fountains.!!!La Pyramide.

The new entrance to the Paris Louvre had become almost as famous as the museum itself. The controversial, neomodern glass pyramid designed by Chinese-born American architect I. M. Pei still evoked scorn from traditionalists who felt it destroyed the dignity of the Renaissance courtyard. Goethe had described architecture as frozen music, and Pei's critics described this pyramid as fingernails on a chalkboard. Progressive admirers, though, hailed Pei's seventy-one-foot-tall transparent pyramid as a dazzling synergy of ancient structure and modern method—a symbolic link between the old and new—helping usher the Louvre into the next millennium.

"Do you like our pyramid?" the agent asked.

Langdon frowned. The French, it seemed, loved to ask Americans this. It was a loaded question, of course. Admitting you liked the pyramid made you a tasteless American, and expressing dislike was an insult to the French.

"Mitterrand was a bold man," Langdon replied, splitting the difference. The late French president who had commissioned the pyramid was said to have suffered from a "Pharaoh complex." Singlehandedly responsible for filling Paris with Egyptian obelisks, art, and artifacts.

François Mitterrand had an affinity for Egyptian culture that was so all-consuming that the French still referred to him as the Sphinx.

"What is the captain's name?" Langdon asked, changing topics.

"Bezu Fache," the driver said, approaching the pyramid's main entrance. "We call him!!!le Taureau."

Langdon glanced over at him, wondering if every Frenchman had a mysterious animal epithet. "You call your captain!!!the Bull?"

The man arched his eyebrows. "Your French is better than you admit, Monsieur Langdon."

My French stinks, Langdon thought, but my zodiac iconography is pretty good. Taurus was always the bull. Astrology was a symbolic constant all over the world.

The agent pulled the car to a stop and pointed between two fountains to a large door in the side of the pyramid. "There is the entrance. Good luck, monsieur."

"You're not coming?"

"My orders are to leave you here. I have other business to attend to."

Langdon heaved a sigh and climbed out. It's your circus.

The agent revved his engine and sped off.

As Langdon stood alone and watched the departing taillights, he realized he could easily reconsider, exit the courtyard, grab a taxi, and head home to bed. Something told him it was probably a lousy idea.

As he moved toward the mist of the fountains, Langdon had the uneasy sense he was crossing an imaginary threshold into another world. The dreamlike quality of the evening was settling around him again. Twenty minutes ago he had been asleep in his hotel room. Now he was standing in front of a transparent pyramid built by the Sphinx, waiting for a policeman they called the Bull.!!!I'm trapped in a Salvador Dali painting, he thought.

Langdon strode to the main entrance—an enormous revolving door. The foyer beyond was dimly lit and deserted.!!!Do I knock?

Langdon wondered if any of Harvard's revered Egyptologists had ever knocked on the front door of a pyramid and expected an answer. He raised his hand to bang on the glass, but out of the darkness below, a figure appeared, striding up the curving staircase. The man was stocky and dark, almost Neanderthal, dressed in a dark double-breasted suit that strained to cover his wide shoulders. He advanced with unmistakable authority on squat, powerful legs. He was speaking on his cell phone but finished the call as he arrived. He motioned for Langdon to enter.

"I am Bezu Fache," he announced as Langdon pushed through the revolving door. "Captain of the Central Directorate Judicial Police." His tone was fitting—a guttural rumble… like a gathering storm.

Langdon held out his hand to shake. "Robert Langdon."

Fache's enormous palm wrapped around Langdon's with crushing force.

"I saw the photo," Langdon said. "Your agent said Jacques Saunière himself did—"

"Mr. Langdon," Fache's ebony eyes locked on. "What you see in the photo is only the beginning of what Saunière did."
