ng had felt like a bizarre dream. I'm about to dash out of the Louvre... a fugitive. Sauniure's clever anagrammatic message was still on his mind, and Langdon wondered what Sophie would find at the Mona Lisa... if anything. She had seemed certain her grandfather meant for her to visit the famous painting one more time. As plausible an interpretation as this seemed, Langdon felt haunted now by a troubling paradox. P.S. Find Robert Langdon. Sauniure had written Langdon's name on the floor, commanding Sophie to find him. But why? Merely so Langdon could help her break an anagram? It seemed quite unlikely. After all, Sauniure had no reason to think Langdon was especially skilled at anagrams. We've never even met. More important, Sophie had stated flat out that she should have broken the anagram on her own. It had been Sophie who spotted the Fibonacci sequence, and, no doubt, Sophie who, if given a little more time, would have deciphered the message with no help from Langdon. Sophie was supposed to break that anagram on her own. Langdon was suddenly feeling more certain about this, and yet the conclusion left an obvious gaping lapse in the logic of Sauniure's actions. Why me? Langdon wondered, heading down the hall. Why was Sauniure's dying wish that his estranged granddaughter find me? What is it that Sauniure thinks I know? With an unexpected jolt, Langdon stopped short. Eyes wide, he dug in his pocket and yanked out the computer printout. He stared at the last line of Sauniure's message. P.S. Find Robert Langdon. He fixated on two letters. P.S. In that instant, Langdon felt Sauniure's puzzling mix of symbolism fall into stark focus. Like a peal of thunder, a career's worth of symbology and history came crashing down around him. Everything Jacques Sauniure had done tonight suddenly made perfect sense. Langdon's thoughts raced as he tried to assemble the implications of what this all meant. Wheeling, he stared back in the direction from which he had come. Is there time? He knew it didn't matter. Without hesitation, Langdon broke into a sprint back toward the stairs. CHAPTER 22 Kneeling in the first pew, Silas pretended to pray as he scanned the layout of the sanctuary. Saint-Sulpice, like most churches, had been built in the shape of a giant Roman cross. Its long central section--the nave--led directly to the main altar, where it was transversely intersected by a shorter section, known as the transept. The intersection of nave and transept occurred directly beneath the main cupola and was considered the heart of the church... her most sacred and mystical point. Not tonight, Silas thought. Saint-Sulpice hides her secrets elsewhere. Turning his head to the right, he gazed into the south transept, toward the open area of floor beyond the end of the pews, to the object his victims had described. There it is. Embedded in the gray granite floor, a thin polished strip of brass glistened in the stone... a golden line slanting across the church's floor. The line bore graduated markings, like a ruler. It was a gnomon, Silas had been told, a pagan astronomical device like a sundial. Tourists, scientists, historians, and pagans from around the world came to Saint-Sulpice to gaze upon this famous line. The Rose Line. Slowly, Silas let his eyes trace the path of the brass strip as it made its way across the floor from his right to left, slanting in front of him at an awkward angle, entirely at odds with the symmetry of the church. Slicing across the main altar itself, the line looked to Silas like a slash wound across a beautiful face. The strip cleaved the communion rail in two and then crossed the entire width of the church, finally reaching the corner of the north transept, where it arrived at the base of a most unexpected structure. A colossal Egyptian obelisk. Here, the glistening Rose Line took a ninety-degree vertical turn and continued directly up the face of the obelisk itself, ascending thirty-three feet to the very tip of the pyramidical apex, where it finally ceased. The Rose Line, Silas thought. The brotherhood hid the keystone at the Rose Line. Earlier tonight, when Silas told the Teacher that the Priory keystone was hidden inside Saint-Sulpice, the Teacher had sounded doubtful. But when Silas added that the brothers had all given him a precise location, with relation to a brass line running through Saint-Sulpice, the Teacher had gasped with revelation. "You speak of the Rose Line!" The Teacher quickly told Silas of Saint-Sulpice's famed architectural oddity--a strip of brass that segmented the sanctuary on a perfect north-south axis. It was an ancient sundial of sorts, a vestige of the pagan temple that had once stood on this very spot. The sun's rays, shining through the oculus on the south wall, moved farther down the line every day, indicating the passage of time, from solstice to solstice. The north-south stripe had been known as the Rose Line. For centuries, the symbol of the Rose had been associated with maps and guiding souls in the proper direction. The Compass Rose--drawn on almost every map--indicated North, East, South, and West. Originally known as the Wind Rose, it denoted the directions of the thirty-two winds, blowing from the directions of eight major winds, eight half-winds, and sixteen quarter-winds. When diagrammed inside a circle, these thirty-two points of the compass perfectly resembled a traditional thirty-two petal rose bloom. To this day, the fundamental navigational tool was still known as a Compass Rose, its northernmost direction still marked by an arrowhead... or, more commonly, the symbol of the fleur-de-lis. On a globe, a Rose Line--also called a meridian or longitude--was any imaginary line drawn from the North Pole to the South Pole. There were, of course, an infinite number of Rose Lines because every point on the globe could have a longitude drawn through it connecting north and south poles. The question for early navigators was which of these lines would be called the Rose Line--the zero longitude--the line from which all other longitudes on earth would be measured. Today that line was in Greenwich, England. But it had not always been. Long before the establishment of Greenwich as the prime meridian, the zero longitude of the entire world had passed directly through Paris, and through the Church of Saint-Sulpice. The brass marker in Saint-Sulpice was a memorial to the world's first prime meridian, and although Greenwich had stripped Paris of the honor in 1888, the original Rose Line was still visible today. "And so the legend is true," the Teacher had told Silas. "The Priory keystone has been said to lie 'beneath the Sign of the Rose.' " Now, still on his knees in a pew, Silas glanced around the church and listened to make sure no one was there. For a moment, he thought he heard a rustling in the choir balcony. He turned and gazed up for several seconds. Nothing. I am alone. Standing now, he faced the altar and genuflected three times. Then he turned left and followed the brass line due north toward the obelisk. At that moment, at Leonardo da Vinci International Airport in Rome, the jolt of tires hitting the runway startled Bishop Aringarosa from his slumber. I drifted off, he thought, impressed he was relaxed enough to sleep. "Benvenuto a Roma," the intercom announced. Sitting up, Aringarosa straightened his black cassock and allowed himself a rare smile. This was one trip he had been happy to make. I have been on the defensive for too long. Tonight, however, the rules had changed. Only five months ago, Aringarosa had feared for the future of the Faith. Now, as if by the will of God, the solution had presented itself. Divine intervention. If all went as planned tonight in Paris, Aringarosa would soon be in possession of something that would make him the most powerful man in Christendom. CHAPTER 23 Sophie arrived breathless outside the large wooden doors of the Salle des Etats--the room that housed the Mona Lisa. Before entering, she gazed reluctantly farther down the hall, twenty yards or so, to the spot where her grandfather's body still lay under the spotlight. The remorse that gripped her was powerful and sudden, a deep sadness laced with guilt. The man had reached out to her so many times over the past ten years, and yet Sophie had remained immovable--leaving his letters and packages unopened in a bottom drawer and denying his efforts to see her. He lied to me! Kept appalling secrets! What was I supposed to do? And so she had blocked him out. Completely. Now her grandfather was dead, and he was talking to her from the grave. The Mona Lisa. She reached for the huge wooden doors, and pushed. The entryway yawned open. Sophie stood on the threshold a moment, scanning the large rectangular chamber beyond. It too was bathed in a soft red light. The Salle des Etats was one of this museum's rare culs-de-sac--a dead end and the only room off the middle of the Grand Gallery. This door, the chamber's sole point of entry, faced a dominating fifteen-foot Botticelli on the far wall. Beneath it, centered on the parquet floor, an immense octagonal viewing divan served as a welcome respite for thousands of visitors to rest their legs while they admired the Louvre's most valuable asset. Even before Sophie entered, though, she knew she was missing something. A black light. She gazed down the hall at her grandfather under the lights in the distance, surrounded by electronic gear. If he had written anything in here, he almost certainly would have written it with the watermark stylus. Taking a deep breath, Sophie hurried down to the well-lit crime scene. Unable to look at her grandfather, she focused solely on the PTS tools. Finding a small ultraviolet penlight, she slipped it in the pocket of her sweater and hurried back up the hallway toward the open doors of the Salle des Etats. Sophie turned the corner and stepped over the threshold. Her entrance, however, was met by an unexpected sound of muffled footsteps racing toward her from inside the chamber. There's someone in here! A ghostly figure emerged suddenly from out of the reddish haze. Sophie jumped back. "There you are!" Langdon's hoarse whisper cut the air as his silhouette slid to a stop in front of her. Her relief was only momentary. "Robert, I told you to get out of here! If Fache--" "Where were you?" "I had to get the black light," she whispered, holding it up. "If my grandfather left me a message--" "Sophie, listen." Langdon caught his breath as his blue eyes held her firmly. "The letters P.S.... do they mean anything else to you? Anything at all?" Afraid their voices might echo down the hall, Sophie pulled him into the Salle des Etats and closed the enormous twin doors silently, sealing them inside. "I told you, the initials mean Princess Sophie." "I know, but did you ever see them anywhere else? Did your grandfather ever use P.S. in any other way? As a monogram, or maybe on stationery or a personal item?" The question startled her. How would Robert know that? Sophie had indeed seen the initials P.S. once before, in a kind of monogram. It was the day before her ninth birthday. She was secretly combing the house, searching for hidden birthday presents. Even then, she could not bear secrets kept from her. What did Grand-pure get for me this year? She dug through cupboards and drawers. Did he get me the doll I wanted? Where would he hide it? Finding nothing in the entire house, Sophie mustered the courage to sneak into her grandfather's bedroom. The room was off-limits to her, but her grandfather was downstairs asleep on the couch. I'll just take a fast peek! Tiptoeing across the creaky wood floor to his closet, Sophie peered on the shelves behind his clothing. Nothing. Next she looked under the bed. Still nothing. Moving to his bureau, she opened the drawers and one by one began pawing carefully through them. There must be something for me here! As she reached the bottom drawer, she still had not found any hint of a doll. Dejected, she opened the final drawer and pulled aside some black clothes she had never seen him wear. She was about to close the drawer when her eyes caught a glint of gold in the back of the drawer. It looked like a pocket watch chain, but she knew he didn't wear one. Her heart raced as she realized what it must be. A necklace! Sophie carefully pulled the chain from the drawer. To her surprise, on the end was a brilliant gold key. Heavy and shimmering. Spellbound, she held it up. It looked like no key she had ever seen. Most keys were flat with jagged teeth, but this one had a triangular column with little pockmarks all over it. Its large golden head was in the shape of a cross, but not a normal cross. This was an even-armed one, like a plus sign. Embossed in the middle of the cross was a strange symbol--two letters intertwined with some kind of flowery design. "P.S.," she whispered, scowling as she read the letters. Whatever could this be? "Sophie?" her grandfather spoke from the doorway. Startled, she spun, dropping the key on the floor with a loud clang. She stared down at the key, afraid to look up at her grandfather's face. "I... was looking for my birthday present," she said, hanging her head, knowing she had betrayed his trust. For what seemed like an eternity, her grandfather stood silently in the doorway. Finally, he let out a long troubled breath. "Pick up the key, Sophie." Sophie retrieved the key. Her grandfather walked in. "Sophie, you need to respect other people's privacy." Gently, he knelt down and took the key from her. "This key is very special. If you had lost it..." Her grandfather's quiet voice made Sophie feel even worse. "I'm sorry, Grand-pure. I really am." She paused. "I thought it was a necklace for my birthday." He gazed at her for several seconds. "I'll say this once more, Sophie, because it's important. You need to learn to respect other people's privacy." "Yes, Grand-pure." "We'll talk about this some other time. Right now, the garden needs to be weeded." Sophie hurried outside to do her chores. The next morning, Sophie received no birthday present from her grandfather. She hadn't expected one, not after what she had done. But he didn't even wish her happy birthday all day. Sadly, she trudged up to bed that night. As she climbed in, though, she found a note card lying on her pillow. On the card was written a simple riddle. Even before she solved the riddle, she was smiling. I know what this is! Her grandfather had done this for her last Christmas morning. A treasure hunt! Eagerly, she pored over the riddle until she solved it. The solution pointed her to another part of the house, where she found another card and another riddle. She solved this one too, racing on to the next card. Running wildly, she darted back and forth across the house, from clue to clue, until at last she found a clue that directed her back to her own bedroom. Sophie dashed up the stairs, rushed into her room, and stopped in her tracks. There in the middle of the room sat a shining red bicycle with a ribbon tied to the handlebars. Sophie shrieked with delight. "I know you asked for a doll," her grandfather said, smiling in the corner. "I thought you might like this even better." The next day, her grandfather taught her to ride, running beside her down the walkway. When Sophie steered out over the thick lawn and lost her balance, they both went tumbling onto the grass, rolling and laughing. "Grand-pure," Sophie said, hugging him. "I'm really sorry about the key." "I know, sweetie. You're forgiven. I can't possibly stay mad at you. Grandfathers and granddaughters always forgive each other." Sophie knew she shouldn't ask, but she couldn't help it. "What does it open? I never saw a key like that. It was very pretty." Her grandfather was silent a long moment, and Sophie could see he was uncertain how to answer. Grand-pure never lies. "It opens a box," he finally said. "Where I keep many secrets." Sophie pouted. "I hate secrets!" "I know, but these are important secrets. And someday, you'll learn to appreciate them as much as I do." "I saw letters on the key, and a flower." "Yes, that's my favorite flower. It's called a fleur-de-lis. We have them in the garden. The white ones. In English we call that kind of flower a lily." "I know those! They're my favorite too!" "Then I'll make a deal with you." Her grandfather's eyebrows raised the way they always did when he was about to give her a challenge. "If you can keep my key a secret, and never talk about it ever again, to me or anybody, then someday I will give it to you." Sophie couldn't believe her ears. "You will?" "I promise. When the time comes, the key will be yours. It has your name on it." Sophie scowled. "No it doesn't. It said P.S. My name isn't P.S.!" Her grandfather lowered his voice and looked around as if to make sure no one was listening. "Okay, Sophie, if you must know, P.S. is a code. It's your secret initials." Her eyes went wide. "I have secret initials?" "Of course. Granddaughters always have secret initials that only their grandfathers know." "P.S.?" He tickled her. "Princesse Sophie." She giggled. "I'm not a princess!" He winked. "You are to me." From that day on, they never again spoke of the key. And she became his Princess Sophie. Inside the Salle des Etats, Sophie stood in silence and endured the sharp pang of loss. "The initials," Langdon whispered, eyeing her strangely. "Have you seen them?" Sophie sensed her grandfather's voice whispering in the corridors of the museum. Never speak of this key, Sophie. To me or to anyone. She knew she had failed him in forgiveness, and she wondered if she could break his trust again. P.S. Find Robert Langdon. Her grandfather wanted Langdon to help. Sophie nodded. "Yes, I saw the initials P.S. once. When I was very young." "Where?" Sophie hesitated. "On something very important to him." Langdon locked eyes with her. "Sophie, this is crucial. Can you tell me if the initials appeared with a symbol? A fleur-de-lis?" Sophie felt herself staggering backward in amazement. "But... how could you possibly know that!" Langdon exhaled and lowered his voice. "I'm fairly certain your grandfather was a member of a secret society. A very old covert brotherhood." Sophie felt a knot tighten in her stomach. She was certain of it too. For ten years she had tried to forget the incident that had confirmed that horrifying fact for her. She had witnessed something unthinkable. Unforgivable. "The fleur-de-lis," Langdon said, "combined with the initials P.S., that is the brotherhood's official device. Their coat of arms. Their logo." "How do you know this?" Sophie was praying Langdon was not going to tell her that he himself was a member. "I've written about this group," he said, his voice tremulous with excitement. "Researching the symbols of secret societies is a specialty of mine. They call themselves the Prieuru de Sion--the Priory of Sion. They're based here in France and attract powerful members from all over Europe. In fact, they are one of the oldest surviving secret societies on earth." Sophie had never heard of them. Langdon was talking in rapid bursts now. "The Priory's membership has included some of history's most cultured individuals: men like Botticelli, Sir Isaac Newton, Victor Hugo." He paused, his voice brimming now with academic zeal. "And, Leonardo da Vinci." Sophie stared. "Da Vinci was in a secret society?" "Da Vinci presided over the Priory between 1510 and 1519 as the brotherhood's Grand Master, which might help explain your grandfather's passion for Leonardo's work. The two men share a historical fraternal bond. And it all fits perfectly with their fascination for goddess iconology, paganism, feminine deities, and contempt for the Church. The Priory has a well-documented history of reverence for the sacred feminine." "You're telling me this group is a pagan goddess worship cult?" "More like the pagan goddess worship cult. But more important, they are known as the guardians of an ancient secret. One that made them immeasurably powerful." Despite the total conviction in Langdon's eyes, Sophie's gut reaction was one of stark disbelief. A secret pagan cult? Once headed by Leonardo da Vinci? It all sounded utterly absurd. And yet, even as she dismissed it, she felt her mind reeling back ten years--to the night she had mistakenly surprised her grandfather and witnessed what she still could not accept. Could that explain--? "The identities of living Priory members are kept extremely secret," Langdon said, "but the P.S. and fleur-de-lis that you saw as a child are proof. It could only have been related to the Priory." Sophie realized now that Langdon knew far more about her grandfather than she had previously imagined. This American obviously had volumes to share with her, but this was not the place. "I can't afford to let them catch you, Robert. There's a lot we need to discuss. You need to go!" Langdon heard only the faint murmur of her voice. He wasn't going anywhere. He was lost in another place now. A place where ancient secrets rose to the surface. A place where forgotten histories emerged from the shadows. Slowly, as if moving underwater, Langdon turned his head and gazed through the reddish haze toward the Mona Lisa. The fleur-de-lis... the flower of Lisa... the Mona Lisa. It was all intertwined, a silent symphony echoing the deepest secrets of the Priory of Sion and Leonardo da Vinci. A few miles away, on the riverbank beyond Les Invalides, the bewildered driver of a twin-bed Trailor truck stood at gunpoint and watched as the captain of the Judicial Police let out a guttural roar of rage and heaved a bar of soap out into the turgid waters of the Seine. CHAPTER 24 Silas gazed upward at the Saint-Sulpice obelisk, taking in the length of the massive marble shaft. His sinews felt taut with exhilaration. He glanced around the church one more time to make sure he was alone. Then he knelt at the base of the structure, not out of reverence, but out of necessity. The keystone is hidden beneath the Rose Line. At the base of the Sulpice obelisk. All the brothers had concurred. On his knees now, Silas ran his hands across the stone floor. He saw no cracks or markings to indicate a movable tile, so he began rapping softly with his knuckles on the floor. Following the brass line closer to the obelisk, he knocked on each tile adjacent to the brass line. Finally, one of them echoed strangely. There's a hollow area beneath the floor! Silas smiled. His victims had spoken the truth. Standing, he searched the sanctuary for something with which to break the floor tile. High above Silas, in the balcony, Sister Sandrine stifled a gasp. Her darkest fears had just been confirmed. This visitor was not who he seemed. The mysterious Opus Dei monk had come to Saint-Sulpice for another purpose. A secret purpose. You are not the only one with secrets, she thought. Sister Sandrine Bieil was more than the keeper of this church. She was a sentry. And tonight, the ancient wheels had been set in motion. The arrival of this stranger at the base of the obelisk was a signal from the brotherhood. It was a silent call of distress. CHAPTER 25 The U.S. Embassy in Paris is a compact complex on Avenue Gabriel, just north of the Champs-Elysues. The three-acre compound is considered U.S. soil, meaning all those who stand on it are subject to the same laws and protections as they would encounter standing in the United States. The embassy's night operator was reading Time magazine's International Edition when the sound of her phone interrupted. "U.S. Embassy," she answered. "Good evening." The caller spoke English accented with French. "I need some assistance." Despite the politeness of the man's words, his tone sounded gruff and official. "I was told you had a phone message for me on your automated system. The name is Langdon. Unfortunately, I have forgotten my three-digit access code. If you could help me, I would be most grateful." The operator paused, confused. "I'm sorry, sir. Your message must be quite old. That system was removed two years ago for security precautions. Moreover, all the access codes were five-digit. Who told you we had a message for you?" "You have no automated phone system?" "No, sir. Any message for you would be handwritten in our services department. What was your name again?" But the man had hung up. Bezu Fache felt dumbstruck as he paced the banks of the Seine. He was certain he had seen Langdon dial a local number, enter a three-digit code, and then listen to a recording. But if Langdon didn't phone the embassy, then who the hell did he call? It was at that moment, eyeing his cellular phone, that Fache realized the answers were in the palm of his hand. Langdon used my phone to place that call. Keying into the cell phone's menu, Fache pulled up the list of recently dialed numbers and found the call Langdon had placed. A Paris exchange, followed by the three-digit code 454. Redialing the phone number, Fache waited as the line began ringing. Finally a woman's voice answered. "Bonjour, vous utes bien chez Sophie Neveu," the recording announced. "Je suis absente pour le moment, mais..." Fache's blood was boiling as he typed the numbers 4... 5... 4. CHAPTER 26 Despite her monumental reputation, the Mona Lisa was a mere thirty-one inches by twenty-one inches--smaller even than the posters of her sold in the Louvre gift shop. She hung on the northwest wall of the Salle des Etats behind a two-inch-thick pane of protective Plexiglas. Painted on a poplar wood panel, her ethereal, mist-filled atmosphere was attributed to Da Vinci's mastery of the sfumato style, in which forms appear to evaporate into one another. Since taking up residence in the Louvre, the Mona Lisa--or La Jaconde as they call her in France--had been stolen twice, most recently in 1911, when she disappeared from the Louvre's "satte impunutrable"--Le Salon Carre. Parisians wept in the streets and wrote newspaper articles begging the thieves for the painting's return. Two years later, the Mona Lisa was discovered hidden in the false bottom of a trunk in a Florence hotel room. Langdon, now having made it clear to Sophie that he had no intention of leaving, moved with her across the Salle des Etats. The Mona Lisa was still twenty yards ahead when Sophie turned on the black light, and the bluish crescent of penlight fanned out on the floor in front of them. She swung the beam back and forth across the floor like a minesweeper, searching for any hint of luminescent ink. Walking beside her, Langdon was already feeling the tingle of anticipation that accompanied his face-to-face reunions with great works of art. He strained to see beyond the cocoon of purplish light emanating from the black light in Sophie's hand. To the left, the room's octagonal viewing divan emerged, looking like a dark island on the empty sea of parquet. Langdon could now begin to see the panel of dark glass on the wall. Behind it, he knew, in the confines of her own private cell, hung the most celebrated painting in the world. The Mona Lisa's status as the most famous piece of art in the world, Langdon knew, had nothing to do with her enigmatic smile. Nor was it due to the mysterious interpretations attributed her by many art historians and conspiracy buffs. Quite simply, the Mona Lisa was famous because Leonardo da Vinci claimed she was his finest accomplishment. He carried the painting with him whenever he traveled and, if asked why, would reply that he found it hard to part with his most sublime expression of female beauty. Even so, many art historians suspected Da Vinci's reverence for the Mona Lisa had nothing to do with its artistic mastery. In actuality, the painting was a surprisingly ordinary sfumato portrait. Da Vinci's veneration for this work, many claimed, stemmed from something far deeper: a hidden message in the layers of paint. The Mona Lisa was, in fact, one of the world's most documented inside jokes. The painting's well-documented collage of double entendres and playful allusions had been revealed in most art history tomes, and yet, incredibly, the public at large still considered her smile a great mystery. No mystery at all, Langdon thought, moving forward and watching as the faint outline of the painting began to take shape. No mystery at all. Most recently Langdon had shared the Mona Lisa's secret with a rather unlikely group--a dozen inmates at the Essex County Penitentiary. Langdon's jail seminar was part of a Harvard outreach program attempting to bring education into the prison system--Culture for Convicts, as Langdon's colleagues liked to call it. Standing at an overhead projector in a darkened penitentiary library, Langdon had shared the Mona Lisa's secret with the prisoners attending class, men whom he found surprisingly engaged--rough, but sharp. "You may notice," Langdon told them, walking up to the projected image of the Mona Lisa on the library wall, "that the background behind her face is uneven." Langdon motioned to the glaring discrepancy. "Da Vinci painted the horizon line on the left significantly lower than the right." "He screwed it up?" one of the inmates asked. Langdon chuckled. "No. Da Vinci didn't do that too often. Actually, this is a little trick Da Vinci played. By lowering the countryside on the left, Da Vinci made Mona Lisa look much larger from the left side than from the right side. A little Da Vinci inside joke. Historically, the concepts of male and female have assigned sides--left is female, and right is male. Because Da Vinci was a big fan of feminine principles, he made Mona Lisa look more majestic from the left than the right." "I heard he was a fag," said a small man with a goatee. Langdon winced. "Historians don't generally put it quite that way, but yes, Da Vinci was a homosexual." "Is that why he was into that whole feminine thing?" "Actually, Da Vinci was in tune with the balance between male and female. He believed that a human soul could not be enlightened unless it had both male and female elements." "You mean like chicks with dicks?" someone called. This elicited a hearty round of laughs. Langdon considered offering an etymological sidebar about the word hermaphrodite and its ties to Hermes and Aphrodite, but something told him it would be lost on this crowd. "Hey, Mr. Langford," a muscle-bound man said. "Is it true that the Mona Lisa is a picture of Da Vinci in drag? I heard that was true." "It's quite possible," Langdon said. "Da Vinci was a prankster, and computerized analysis of the Mona Lisa and Da Vinci's self-portraits confirm some startling points of congruency in their faces. Whatever Da Vinci was up to," Langdon said, "his Mona Lisa is neither male nor female. It carries a subtle message of androgyny. It is a fusing of both." "You sure that's not just some Harvard bullshit way of saying Mona Lisa is one ugly chick." Now Langdon laughed. "You may be right. But actually Da Vinci left a big clue that the painting was supposed to be androgynous. Has anyone here ever heard of an Egyptian god named Amon?" "Hell yes!" the big guy said. "God of masculine fertility!" Langdon was stunned. "It says so on every box of Amon condoms." The muscular man gave a wide grin. "It's got a guy with a ram's head on the front and says he's the Egyptian god of fertility." Langdon was not familiar with the brand name, but he was glad to hear the prophylactic manufacturers had gotten their hieroglyphs right. "Well done. Amon is indeed represented as a man with a ram's head, and his promiscuity and curved horns are related to our modern sexual slang 'horny.' " "No shit!" "No shit," Langdon said. "And do you know who Amon's counterpart was? The Egyptian goddess of fertility?" The question met with several seconds of silence. "It was Isis," Langdon told them, grabbing a grease pen. "So we have the male god, Amon." He wrote it down. "And the female goddess, Isis, whose ancient pictogram was once called L'ISA." Langdon finished writing and stepped back from the projector. AMON L'ISA "Ring any bells?" he asked. "Mona Lisa... holy crap," somebody gasped. Langdon nodded. "Gentlemen, not only does the face of Mona Lisa look androgynous, but her name is an anagram of the divine union of male and female. And that, my friends, is Da Vinci's little secret, and the reason for Mona Lisa's knowing smile." "My grandfather was here," Sophie said, dropping suddenly to her knees, now only ten feet from the Mona Lisa. She pointed the black light tentatively to a spot on the parquet floor. At first Langdon saw nothing. Then, as he knelt beside her, he saw a tiny droplet of dried liquid that was luminescing. Ink? Suddenly he recalled what black lights were actually used for. Blood. His senses tingled. Sophie was right. Jacques Sauniure had indeed paid a visit to the Mona Lisa before he died. "He wouldn't have come here without a reason," Sophie whispered, standing up. "I know he left a message for me here." Quickly striding the final few steps to the Mona Lisa, she illuminated the floor directly in front of the painting. She waved the light back and forth across the bare parquet. "There's nothing here!" At that moment, Langdon saw a faint purple glimmer on the protective glass before the Mona Lisa. Reaching down, he took Sophie's wrist and slowly moved the light up to the painting itself. They both froze. On the glass, six words glowed in purple, scrawled directly across the Mona Lisa's face. CHAPTER 27 Seated at Sauniure's desk, Lieutenant Collet pressed the phone to his ear in disbelief. Did I hear Fache correctly? "A bar of soap? But how could Langdon have known about the GPS dot?" "Sophie Neveu," Fache replied. "She told him." "What! Why?" "Damned good question, but I just heard a recording that confirms she tipped him off." Collet was speechless. What was Neveu thinking? Fache had proof that Sophie had interfered with a DCPJ sting operation? Sophie Neveu was not only going to be fired, she was also going to jail. "But, Captain... then where is Langdon now?" "Have any fire alarms gone off there?" "No, sir." "And no one has come out under the Grand Gallery gate?" "No. We've got a Louvre security officer on the gate. Just as you requested." "Okay, Langdon must still be inside the Grand Gallery." "Inside? But what is he doing?" "Is the Louvre security guard armed?" "Yes, sir. He's a senior warden." "Send him in," Fache commanded. "I can't get my men back to the perimeter for a few minutes, and I don't want Langdon breaking for an exit." Fache paused. "And you'd better tell the guard Agent Neveu is probably in there with him." "Agent Neveu left, I thought." "Did you actually see her leave?" "No, sir, but--" "Well, nobody on the perimeter saw her leave either. They only saw her go in." Collet was flabbergasted by Sophie Neveu's bravado. She's still inside the building? "Handle it," Fache ordered. "I want Langdon and Neveu at gunpoint by the time I get back." As the Trailor truck drove off, Captain Fache rounded up his men. Robert Langdon had proven an elusive quarry tonight, and with Agent Neveu now helping him, he might be far harder to corner than expected. Fache decided not to take any chances. Hedging his bets, he ordered half of his men back to the Louvre perimeter. The other half he sent to guard the only location in Paris where Robert Langdon could find safe harbor. CHAPTER 28 Inside the Salle des Etats, Langdon stared in astonishment at the six words glowing on the Plexiglas. The text seemed to hover in space, casting a jagged shadow across Mona Lisa's mysterious smile. "The Priory," Langdon whispered. "This proves your grandfather was a member!" Sophie looked at him in confusion. "You understand this?" "It's flawless," Langdon said, nodding as his thoughts churned. "It's a proclamation of one of the Priory's most fundamental philosophies!" Sophie looked baffled in the glow of the message scrawled across the Mona Lisa's face. SO DARK THE CON OF MAN "Sophie," Langdon said, "the Priory's tradition of perpetuating goddess worship is based on a belief that powerful men in the early Christian church 'conned' the world by propagating lies that devalued the female and tipped the scales in favor of the masculine." Sophie remained silent, staring at the words. "The Priory believes that Constantine and his male successors successfully converted the world from matriarchal paganism to patriarchal Christianity by waging a campaign of propaganda that demonized the sacred feminine, obliterating the goddess from modern religion forever." Sophie's expression remained uncertain. "My grandfather sent me to this spot to find this. He must be trying to tell me more than that." Langdon understood her meaning. She thinks this is another code. Whether a hidden meaning existed here or not, Langdon could not immediately say. His mind was still grappling with the bold clarity of Sauniure's outward message. So dark the con of man, he thought. So dark indeed. Nobody could deny the enormous good the modern Church did in today's troubled world, and yet the Church had a deceitful and violent history. Their brutal crusade to "reeducate" the pagan and feminine-worshipping religions spanned three centuries, employing methods as inspired as they were horrific. The Catholic Inquisition published the book that arguably could be called the most blood-soaked publication in human history. Malleus Maleficarum--or The Witches' Hammer--indoctrinated the world to "the dangers of f
