he driver's head. The driver instantly dropped his radio, raising his one free hand overhead. "Sophie!" Langdon choked. "What the hell--" "Arrutez!" Sophie commanded the driver. Trembling, the driver obeyed, stopping the car and putting it in park. It was then that Langdon heard the metallic voice of the taxi company's dispatcher coming from the dashboard. "...qui s'appette Agent Sophie Neveu..." the radio crackled. "Et un Amuricain, Robert Langdon..." Langdon's muscles turned rigid. They found us already? "Descendez," Sophie demanded. The trembling driver kept his arms over his head as he got out of his taxi and took several steps backward. Sophie had rolled down her window and now aimed the gun outside at the bewildered cabbie. "Robert," she said quietly, "take the wheel. You're driving." Langdon was not about to argue with a woman wielding a gun. He climbed out of the car and jumped back in behind the wheel. The driver was yelling curses, his arms still raised over his head. "Robert," Sophie said from the back seat, "I trust you've seen enough of our magic forest?" He nodded. Plenty. "Good. Drive us out of here." Langdon looked down at the car's controls and hesitated. Shit. He groped for the stick shift and clutch. "Sophie? Maybe you--" "Go!" she yelled. Outside, several hookers were walking over to see what was going on. One woman was placing a call on her cell phone. Langdon depressed the clutch and jostled the stick into what he hoped was first gear. He touched the accelerator, testing the gas. Langdon popped the clutch. The tires howled as the taxi leapt forward, fishtailing wildly and sending the gathering crowd diving for cover. The woman with the cell phone leapt into the woods, only narrowly avoiding being run down. "Doucement!" Sophie said, as the car lurched down the road. "What are you doing?" "I tried to warn you," he shouted over the sound of gnashing gears. "I drive an automatic!" CHAPTER 39 Although the spartan room in the brownstone on Rue La Bruyure had witnessed a lot of suffering, Silas doubted anything could match the anguish now gripping his pale body. I was deceived. Everything is lost. Silas had been tricked. The brothers had lied, choosing death instead of revealing their true secret. Silas did not have the strength to call the Teacher. Not only had Silas killed the only four people who knew where the keystone was hidden, he had killed a nun inside Saint-Sulpice. She was working against God! She scorned the work of Opus Dei! A crime of impulse, the woman's death complicated matters greatly. Bishop Aringarosa had placed the phone call that got Silas into Saint-Sulpice; what would the abbu think when he discovered the nun was dead? Although Silas had placed her back in her bed, the wound on her head was obvious. Silas had attempted to replace the broken tiles in the floor, but that damage too was obvious. They would know someone had been there. Silas had planned to hide within Opus Dei when his task here was complete. Bishop Aringarosa will protect me. Silas could imagine no more blissful existence than a life of meditation and prayer deep within the walls of Opus Dei's headquarters in New York City. He would never again set foot outside. Everything he needed was within that sanctuary. Nobody will miss me. Unfortunately, Silas knew, a prominent man like Bishop Aringarosa could not disappear so easily. I have endangered the bishop. Silas gazed blankly at the floor and pondered taking his own life. After all, it had been Aringarosa who gave Silas life in the first place... in that small rectory in Spain, educating him, giving him purpose. "My friend," Aringarosa had told him, "you were born an albino. Do not let others shame you for this. Do you not understand how special this makes you? Were you not aware that Noah himself was an albino?" "Noah of the Ark?" Silas had never heard this. Aringarosa was smiling. "Indeed, Noah of the Ark. An albino. Like you, he had skin white like an angel. Consider this. Noah saved all of life on the planet. You are destined for great things, Silas. The Lord has freed you for a reason. You have your calling. The Lord needs your help to do His work." Over time, Silas learned to see himself in a new light. I am pure. White. Beautiful. Like an angel. At the moment, though, in his room at the residence hall, it was his father's disappointed voice that whispered to him from the past. Tu es un dusastre. Un spectre. Kneeling on the wooden floor, Silas prayed for forgiveness. Then, stripping off his robe, he reached again for the Discipline. CHAPTER 40 Struggling with the gear shift, Langdon managed to maneuver the hijacked taxi to the far side of the Bois de Boulogne while stalling only twice. Unfortunately, the inherent humor in the situation was overshadowed by the taxi dispatcher repeatedly hailing their cab over the radio. "Voiture cinq-six-trois. Ou utes-vous? Rupondez!" When Langdon reached the exit of the park, he swallowed his machismo and jammed on the brakes. "You'd better drive." Sophie looked relieved as she jumped behind the wheel. Within seconds she had the car humming smoothly westward along Allue de Longchamp, leaving the Garden of Earthly Delights behind. "Which way is Rue Haxo?" Langdon asked, watching Sophie edge the speedometer over a hundred kilometers an hour. Sophie's eyes remained focused on the road. "The cab driver said it's adjacent to the Roland Garros tennis stadium. I know that area." Langdon pulled the heavy key from his pocket again, feeling the weight in his palm. He sensed it was an object of enormous consequence. Quite possibly the key to his own freedom. Earlier, while telling Sophie about the Knights Templar, Langdon had realized that this key, in addition to having the Priory seal embossed on it, possessed a more subtle tie to the Priory of Sion. The equal-armed cruciform was symbolic of balance and harmony but also of the Knights Templar. Everyone had seen the paintings of Knights Templar wearing white tunics emblazoned with red equal-armed crosses. Granted, the arms of the Templar cross were slightly flared at the ends, but they were still of equal length. A square cross. Just like the one on this key. Langdon felt his imagination starting to run wild as he fantasized about what they might find. The Holy Grail. He almost laughed out loud at the absurdity of it. The Grail was believed to be somewhere in England, buried in a hidden chamber beneath one of the many Templar churches, where it had been hidden since at least 1500. The era of Grand Master Da Vinci. The Priory, in order to keep their powerful documents safe, had been forced to move them many times in the early centuries. Historians now suspected as many as six different Grail relocations since its arrival in Europe from Jerusalem. The last Grail "sighting" had been in 1447 when numerous eyewitnesses described a fire that had broken out and almost engulfed the documents before they were carried to safety in four huge chests that each required six men to carry. After that, nobody claimed to see the Grail ever again. All that remained were occasional whisperings that it was hidden in Great Britain, the land of King Arthur and the Knights of the Round Table. Wherever it was, two important facts remained: Leonardo knew where the Grail resided during his lifetime. That hiding place had probably not changed to this day. For this reason, Grail enthusiasts still pored over Da Vinci's art and diaries in hopes of unearthing a hidden clue as to the Grail's current location. Some claimed the mountainous backdrop in Madonna of the Rocks matched the topography of a series of cave-ridden hills in Scotland. Others insisted that the suspicious placement of disciples in The Last Supper was some kind of code. Still others claimed that X rays of the Mona Lisa revealed she originally had been painted wearing a lapis lazuli pendant of Isis--a detail Da Vinci purportedly later decided to paint over. Langdon had never seen any evidence of the pendant, nor could he imagine how it could possibly reveal the Holy Grail, and yet Grail aficionados still discussed it ad nauseum on Internet bulletin boards and worldwide-web chat rooms. Everyone loves a conspiracy. And the conspiracies kept coming. Most recently, of course, had been the earthshaking discovery that Da Vinci's famed Adoration of the Magi was hiding a dark secret beneath its layers of paint. Italian art diagnostician Maurizio Seracini had unveiled the unsettling truth, which the New York Times Magazine carried prominently in a story titled "The Leonardo Cover-Up." Seracini had revealed beyond any doubt that while the Adoration's gray-green sketched underdrawing was indeed Da Vinci's work, the painting itself was not. The truth was that some anonymous painter had filled in Da Vinci's sketch like a paint-by-numbers years after Da Vinci's death. Far more troubling, however, was what lay beneath the impostor's paint. Photographs taken with infrared reflectography and X ray suggested that this rogue painter, while filling in Da Vinci's sketched study, had made suspicious departures from the underdrawing... as if to subvert Da Vinci's true intention. Whatever the true nature of the underdrawing, it had yet to be made public. Even so, embarrassed officials at Florence's Uffizi Gallery immediately banished the painting to a warehouse across the street. Visitors at the gallery's Leonardo Room now found a misleading and unapologetic plaque where the Adoration once hung. THIS WORK IS UNDERGOING DIAGNOSTIC TESTS IN PREPARATION FOR RESTORATION. In the bizarre underworld of modern Grail seekers, Leonardo da Vinci remained the quest's great enigma. His artwork seemed bursting to tell a secret, and yet whatever it was remained hidden, perhaps beneath a layer of paint, perhaps enciphered in plain view, or perhaps nowhere at all. Maybe Da Vinci's plethora of tantalizing clues was nothing but an empty promise left behind to frustrate the curious and bring a smirk to the face of his knowing Mona Lisa. "Is it possible," Sophie asked, drawing Langdon back, "that the key you're holding unlocks the hiding place of the Holy Grail?" Langdon's laugh sounded forced, even to him. "I really can't imagine. Besides, the Grail is believed to be hidden in the United Kingdom somewhere, not France." He gave her the quick history. "But the Grail seems the only rational conclusion," she insisted. "We have an extremely secure key, stamped with the Priory of Sion seal, delivered to us by a member of the Priory of Sion--a brotherhood which, you just told me, are guardians of the Holy Grail." Langdon knew her contention was logical, and yet intuitively he could not possibly accept it. Rumors existed that the Priory had vowed someday to bring the Grail back to France to a final resting place, but certainly no historical evidence existed to suggest that this indeed had happened. Even if the Priory had managed to bring the Grail back to France, the address 24 Rue Haxo near a tennis stadium hardly sounded like a noble final resting place. "Sophie, I really don't see how this key could have anything to do with the Grail." "Because the Grail is supposed to be in England?" "Not only that. The location of the Holy Grail is one of the best kept secrets in history. Priory members wait decades proving themselves trustworthy before being elevated to the highest echelons of the fraternity and learning where the Grail is. That secret is protected by an intricate system of compartmentalized knowledge, and although the Priory brotherhood is very large, only four members at any given time know where the Grail is hidden--the Grand Master and his three sunuchaux. The probability of your grandfather being one of those four top people is very slim." My grandfather was one of them, Sophie thought, pressing down on the accelerator. She had an image stamped in her memory that confirmed her grandfather's status within the brotherhood beyond any doubt. "And even if your grandfather were in the upper echelon, he would never be allowed to reveal anything to anyone outside the brotherhood. It is inconceivable that he would bring you into the inner circle." I've already been there, Sophie thought, picturing the ritual in the basement. She wondered if this were the moment to tell Langdon what she had witnessed that night in the Normandy chuteau. For ten years now, simple shame had kept her from telling a soul. Just thinking about it, she shuddered. Sirens howled somewhere in the distance, and she felt a thickening shroud of fatigue settling over her. "There!" Langdon said, feeling excited to see the huge complex of the Roland Garros tennis stadium looming ahead. Sophie snaked her way toward the stadium. After several passes, they located the intersection of Rue Haxo and turned onto it, driving in the direction of the lower numbers. The road became more industrial, lined with businesses. We need number twenty-four, Langdon told himself, realizing he was secretly scanning the horizon for the spires of a church. Don't be ridiculous. A forgotten Templar church in this neighborhood? "There it is," Sophie exclaimed, pointing. Langdon's eyes followed to the structure ahead. What in the world? The building was modern. A squat citadel with a giant, neon equal-armed cross emblazoned atop its facade. Beneath the cross were the words: DEPOSITORY BANK OF ZURICH Langdon was thankful not to have shared his Templar church hopes with Sophie. A career hazard of symbologists was a tendency to extract hidden meaning from situations that had none. In this case, Langdon had entirely forgotten that the peaceful, equal-armed cross had been adopted as the perfect symbol for the flag of neutral Switzerland. At least the mystery was solved. Sophie and Langdon were holding the key to a Swiss bank deposit box. CHAPTER 41 Outside Castel Gandolfo, an updraft of mountain air gushed over the top of the cliff and across the high bluff, sending a chill through Bishop Aringarosa as he stepped from the Fiat. I should have worn more than this cassock, he thought, fighting the reflex to shiver. The last thing he needed to appear tonight was weak or fearful. The castle was dark save the windows at the very top of the building, which glowed ominously. The library, Aringarosa thought. They are awake and waiting. He ducked his head against the wind and continued on without so much as a glance toward the observatory domes. The priest who greeted him at the door looked sleepy. He was the same priest who had greeted Aringarosa five months ago, albeit tonight he did so with much less hospitality. "We were worried about you, Bishop," the priest said, checking his watch and looking more perturbed than worried. "My apologies. Airlines are so unreliable these days." The priest mumbled something inaudible and then said, "They are waiting upstairs. I will escort you up." The library was a vast square room with dark wood from floor to ceiling. On all sides, towering bookcases burgeoned with volumes. The floor was amber marble with black basalt trim, a handsome reminder that this building had once been a palace. "Welcome, Bishop," a man's voice said from across the room. Aringarosa tried to see who had spoken, but the lights were ridiculously low--much lower than they had been on his first visit, when everything was ablaze. The night of stark awakening. Tonight, these men sat in the shadows, as if they were somehow ashamed of what was about to transpire. Aringarosa entered slowly, regally even. He could see the shapes of three men at a long table on the far side of the room. The silhouette of the man in the middle was immediately recognizable--the obese Secretariat Vaticana, overlord of all legal matters within Vatican City. The other two were high-ranking Italian cardinals. Aringarosa crossed the library toward them. "My humble apologies for the hour. We're on different time zones. You must be tired." "Not at all," the secretariat said, his hands folded on his enormous belly. "We are grateful you have come so far. The least we can do is be awake to meet you. Can we offer you some coffee or refreshments?" "I'd prefer we don't pretend this is a social visit. I have another plane to catch. Shall we get to business?" "Of course," the secretariat said. "You have acted more quickly than we imagined." "Have I?" "You still have a month." "You made your concerns known five months ago," Aringarosa said. "Why should I wait?" "Indeed. We are very pleased with your expediency." Aringarosa's eyes traveled the length of the long table to a large black briefcase. "Is that what I requested?" "It is." The secretariat sounded uneasy. "Although, I must admit, we are concerned with the request. It seems quite..." "Dangerous," one of the cardinals finished. "Are you certain we cannot wire it to you somewhere? The sum is exorbitant." Freedom is expensive. "I have no concerns for my own safety. God is with me." The men actually looked doubtful. "The funds are exactly as I requested?" The secretariat nodded. "Large-denomination bearer bonds drawn on the Vatican Bank. Negotiable as cash anywhere in the world." Aringarosa walked to the end of the table and opened the briefcase. Inside were two thick stacks of bonds, each embossed with the Vatican seal and the title PORTATORE, making the bonds redeemable to whoever was holding them. The secretariat looked tense. "I must say, Bishop, all of us would feel less apprehensive if these funds were in cash." I could not lift that much cash, Aringarosa thought, closing the case. "Bonds are negotiable as cash. You said so yourself." The cardinals exchanged uneasy looks, and finally one said, "Yes, but these bonds are traceable directly to the Vatican Bank." Aringarosa smiled inwardly. That was precisely the reason the Teacher suggested Aringarosa get the money in Vatican Bank bonds. It served as insurance. We are all in this together now. "This is a perfectly legal transaction," Aringarosa defended. "Opus Dei is a personal prelature of Vatican City, and His Holiness can disperse monies however he sees fit. No law has been broken here." "True, and yet..." The secretariat leaned forward and his chair creaked under the burden. "We have no knowledge of what you intend to do with these funds, and if it is in any way illegal..." "Considering what you are asking of me," Aringarosa countered, "what I do with this money is not your concern." There was a long silence. They know I'm right, Aringarosa thought. "Now, I imagine you have something for me to sign?" They all jumped, eagerly pushing the paper toward him, as if they wished he would simply leave. Aringarosa eyed the sheet before him. It bore the papal seal. "This is identical to the copy you sent me?" "Exactly." Aringarosa was surprised how little emotion he felt as he signed the document. The three men present, however, seemed to sigh in relief. "Thank you, Bishop," the secretariat said. "Your service to the Church will never be forgotten." Aringarosa picked up the briefcase, sensing promise and authority in its weight. The four men looked at one another for a moment as if there were something more to say, but apparently there was not. Aringarosa turned and headed for the door. "Bishop?" one of the cardinals called out as Aringarosa reached the threshold. Aringarosa paused, turning. "Yes?" "Where will you go from here?" Aringarosa sensed the query was more spiritual than geographical, and yet he had no intention of discussing morality at this hour. "Paris," he said, and walked out the door. CHAPTER 42 The Depository Bank of Zurich was a twenty-four-hour Geldschrank bank offering the full modern array of anonymous services in the tradition of the Swiss numbered account. Maintaining offices in Zurich, Kuala Lumpur, New York, and Paris, the bank had expanded its services in recent years to offer anonymous computer source code escrow services and faceless digitized backup. The bread and butter of its operation was by far its oldest and simplest offering--the anonyme Lager--blind drop services, otherwise known as anonymous safe-deposit boxes. Clients wishing to store anything from stock certificates to valuable paintings could deposit their belongings anonymously, through a series of high-tech veils of privacy, withdrawing items at any time, also in total anonymity. As Sophie pulled the taxi to a stop in front of their destination, Langdon gazed out at the building's uncompromising architecture and sensed the Depository Bank of Zurich was a firm with little sense of humor. The building was a windowless rectangle that seemed to be forged entirely of dull steel. Resembling an enormous metal brick, the edifice sat back from the road with a fifteen-foot-tall, neon, equilateral cross glowing over its facade. Switzerland's reputation for secrecy in banking had become one of the country's most lucrative exports. Facilities like this had become controversial in the art community because they provided a perfect place for art thieves to hide stolen goods, for years if necessary, until the heat was off. Because deposits were protected from police inspection by privacy laws and were attached to numbered accounts rather than people's names, thieves could rest easily knowing their stolen goods were safe and could never be traced to them. Sophie stopped the taxi at an imposing gate that blocked the bank's driveway--a cement-lined ramp that descended beneath the building. A video camera overhead was aimed directly at them, and Langdon had the feeling that this camera, unlike those at the Louvre, was authentic. Sophie rolled down the window and surveyed the electronic podium on the driver's side. An LCD screen provided directions in seven languages. Topping the list was English. INSERT KEY. Sophie took the gold laser-pocked key from her pocket and turned her attention back to the podium. Below the screen was a triangular hole. "Something tells me it will fit," Langdon said. Sophie aligned the key's triangular shaft with the hole and inserted it, sliding it in until the entire shaft had disappeared. This key apparently required no turning. Instantly, the gate began to swing open. Sophie took her foot off the brake and coasted down to a second gate and podium. Behind her, the first gate closed, trapping them like a ship in a lock. Langdon disliked the constricted sensation. Let's hope this second gate works too. This second podium bore familiar directions. INSERT KEY. When Sophie inserted the key, the second gate immediately opened. Moments later they were winding down the ramp into the belly of the structure. The private garage was small and dim, with spaces for about a dozen cars. At the far end, Langdon spied the building's main entrance. A red carpet stretched across the cement floor, welcoming visitors to a huge door that appeared to be forged of solid metal. Talk about mixed messages, Langdon thought. Welcome and keep out. Sophie pulled the taxi into a parking space near the entrance and killed the engine. "You'd better leave the gun here." With pleasure, Langdon thought, sliding the pistol under the seat. Sophie and Langdon got out and walked up the red carpet toward the slab of steel. The door had no handle, but on the wall beside it was another triangular keyhole. No directions were posted this time. "Keeps out the slow learners," Langdon said. Sophie laughed, looking nervous. "Here we go." She stuck the key in the hole, and the door swung inward with a low hum. Exchanging glances, Sophie and Langdon entered. The door shut with a thud behind them. The foyer of the Depository Bank of Zurich employed as imposing a decor as any Langdon had ever seen. Where most banks were content with the usual polished marble and granite, this one had opted for wall-to-wall metal and rivets. Who's their decorator? Langdon wondered. Allied Steel? Sophie looked equally intimidated as her eyes scanned the lobby. The gray metal was everywhere--the floor, walls, counters, doors, even the lobby chairs appeared to be fashioned of molded iron. Nonetheless, the effect was impressive. The message was clear: You are walking into a vault. A large man behind the counter glanced up as they entered. He turned off the small television he was watching and greeted them with a pleasant smile. Despite his enormous muscles and visible sidearm, his diction chimed with the polished courtesy of a Swiss bellhop. "Bonsoir," he said. "How may I help you?" The dual-language greeting was the newest hospitality trick of the European host. It presumed nothing and opened the door for the guest to reply in whichever language was more comfortable. Sophie replied with neither. She simply laid the gold key on the counter in front of the man. The man glanced down and immediately stood straighter. "Of course. Your elevator is at the end of the hall. I will alert someone that you are on your way." Sophie nodded and took her key back. "Which floor?" The man gave her an odd look. "Your key instructs the elevator which floor." She smiled. "Ah, yes." The guard watched as the two newcomers made their way to the elevators, inserted their key, boarded the lift, and disappeared. As soon as the door had closed, he grabbed the phone. He was not calling to alert anyone of their arrival; there was no need for that. A vault greeter already had been alerted automatically when the client's key was inserted outside in the entry gate. Instead, the guard was calling the bank's night manager. As the line rang, the guard switched the television back on and stared at it. The news story he had been watching was just ending. It didn't matter. He got another look at the two faces on the television. The manager answered. "Oui?" "We have a situation down here." "What's happening?" the manager demanded. "The French police are tracking two fugitives tonight." "So?" "Both of them just walked into our bank." The manager cursed quietly. "Okay. I'll contact Monsieur Vernet immediately." The guard then hung up and placed a second call. This one to Interpol. Langdon was surprised to feel the elevator dropping rather than climbing. He had no idea how many floors they had descended beneath the Depository Bank of Zurich before the door finally opened. He didn't care. He was happy to be out of the elevator. Displaying impressive alacrity, a host was already standing there to greet them. He was elderly and pleasant, wearing a neatly pressed flannel suit that made him look oddly out of place--an old-world banker in a high-tech world. "Bonsoir," the man said. "Good evening. Would you be so kind as to follow me, s'il vous plait?" Without waiting for a response, he spun on his heel and strode briskly down a narrow metal corridor. Langdon walked with Sophie down a series of corridors, past several large rooms filled with blinking mainframe computers. "Voici," their host said, arriving at a steel door and opening it for them. "Here you are." Langdon and Sophie stepped into another world. The small room before them looked like a lavish sitting room at a fine hotel. Gone were the metal and rivets, replaced with oriental carpets, dark oak furniture, and cushioned chairs. On the broad desk in the middle of the room, two crystal glasses sat beside an opened bottle of Perrier, its bubbles still fizzing. A pewter pot of coffee steamed beside it. Clockwork, Langdon thought. Leave it to the Swiss. The man gave a perceptive smile. "I sense this is your first visit to us?" Sophie hesitated and then nodded. "Understood. Keys are often passed on as inheritance, and our first-time users are invariably uncertain of the protocol." He motioned to the table of drinks. "This room is yours as long as you care to use it." "You say keys are sometimes inherited?" Sophie asked. "Indeed. Your key is like a Swiss numbered account, which are often willed through generations. On our gold accounts, the shortest safety-deposit box lease is fifty years. Paid in advance. So we see plenty of family turnover." Langdon stared. "Did you say fifty years?" "At a minimum," their host replied. "Of course, you can purchase much longer leases, but barring further arrangements, if there is no activity on an account for fifty years, the contents of that safe-deposit box are automatically destroyed. Shall I run through the process of accessing your box?" Sophie nodded. "Please." Their host swept an arm across the luxurious salon. "This is your private viewing room. Once I leave the room, you may spend all the time you need in here to review and modify the contents of your safe-deposit box, which arrives... over here." He walked them to the far wall where a wide conveyor belt entered the room in a graceful curve, vaguely resembling a baggage claim carousel. "You insert your key in that slot there...." The man pointed to a large electronic podium facing the conveyor belt. The podium had a familiar triangular hole. "Once the computer confirms the markings on your key, you enter your account number, and your safe-deposit box will be retrieved robotically from the vault below for your inspection. When you are finished with your box, you place it back on the conveyor belt, insert your key again, and the process is reversed. Because everything is automated, your privacy is guaranteed, even from the staff of this bank. If you need anything at all, simply press the call button on the table in the center of the room." Sophie was about to ask a question when a telephone rang. The man looked puzzled and embarrassed. "Excuse me, please." He walked over to the phone, which was sitting on the table beside the coffee and Perrier. "Oui?" he answered. His brow furrowed as he listened to the caller. "Oui... oui... d'accord." He hung up, and gave them an uneasy smile. "I'm sorry, I must leave you now. Make yourselves at home." He moved quickly toward the door. "Excuse me," Sophie called. "Could you clarify something before you go? You mentioned that we enter an account number?" The man paused at the door, looking pale. "But of course. Like most Swiss banks, our safe-deposit boxes are attached to a number, not a name. You have a key and a personal account number known only to you. Your key is only half of your identification. Your personal account number is the other half. Otherwise, if you lost your key, anyone could use it." Sophie hesitated. "And if my benefactor gave me no account number?" The banker's heart pounded. Then you obviously have no business here! He gave them a calm smile. "I will ask someone to help you. He will be in shortly." Leaving, the banker closed the door behind him and twisted a heavy lock, sealing them inside. Across town, Collet was standing in the Gare du Nord train terminal when his phone rang. It was Fache. "Interpol got a tip," he said. "Forget the train. Langdon and Neveu just walked into the Paris branch of the Depository Bank of Zurich. I want your men over there right away." "Any leads yet on what Sauniure was trying to tell Agent Neveu and Robert Langdon?" Fache's tone was cold. "If you arrest them, Lieutenant Collet, then I can ask them personally." Collet took the hint. "Twenty-four Rue Haxo. Right away, Captain." He hung up and radioed his men. CHAPTER 43 Andru Vernet--president of the Paris branch of the Depository Bank of Zurich--lived in a lavish flat above the bank. Despite his plush accommodations, he had always dreamed of owning a riverside apartment on L'lle Saint-Louis, where he could rub shoulders with the true cognoscenti, rather than here, where he simply met the filthy rich. When I retire, Vernet told himself, I will fill my cellar with rare Bordeaux, adorn my salon with a Fragonard and perhaps a Boucher, and spend my days hunting for antique furniture and rare books in the Quartier Latin. Tonight, Vernet had been awake only six and a half minutes. Even so, as he hurried through the bank's underground corridor, he looked as if his personal tailor and hairdresser had polished him to a fine sheen. Impeccably dressed in a silk suit, Vernet sprayed some breath spray in his mouth and tightened his tie as he walked. No stranger to being awoken to attend to his international clients arriving from different time zones, Vernet modeled his sleep habits after the Maasai warriors--the African tribe famous for their ability to rise from the deepest sleep to a state of total battle readiness in a matter of seconds. Battle ready, Vernet thought, fearing the comparison might be uncharacteristically apt tonight. The arrival of a gold key client always required an extra flurry of attention, but the arrival of a gold key client who was wanted by the Judicial Police would be an extremely delicate matter. The bank had enough battles with law enforcement over the privacy rights of their clients without proof that some of them were criminals. Five minutes, Vernet told himself. I need these people out of my bank before the police arrive. If he moved quickly, this impending disaster could be deftly sidestepped. Vernet could tell the police that the fugitives in question had indeed walked into his bank as reported, but because they were not clients and had no account number, they were turned away. He wished the damned watchman had not called Interpol. Discretion was apparently not part of the vocabulary of a 15-euro-per-hour watchman. Stopping at the doorway, he took a deep breath and loosened his muscles. Then, forcing a balmy smile, he unlocked the door and swirled into the room like a warm breeze. "Good evening," he said, his eyes finding his clients. "I am Andru Vernet. How can I be of serv--" The rest of the sentence lodged somewhere beneath his Adam's apple. The woman before him was as unexpected a visitor as Vernet had ever had. "I'm sorry, do we know each other?" Sophie asked. She did not recognize the banker, but he for a moment looked as if he'd seen a ghost. "No...," the bank president fumbled. "I don't... believe so. Our services are anonymous." He exhaled and forced a calm smile. "My assistant tells me you have a gold key but no account number? Might I ask how you came by this key?" "My grandfather gave it to me," Sophie replied, watching the man closely. His uneasiness seemed more evident now. "Really? Your grandfather gave you the key but failed to give you the account number?" "I don't think he had time," Sophie said. "He was murdered tonight." Her words sent the man staggering backward. "Jacques Sauniure is dead?" he demanded, his eyes filling with horror. "But... how?!" Now it was Sophie who reeled, numb with shock. "You knew my grandfather?" Banker Andru Vernet looked equally astounded, steadying himself by leaning on an end table. "Jacques and I were dear friends. When did this happen?" "Earlier this evening. Inside the Louvre." Vernet walked to a deep leather chair and sank into it. "I need to ask you both a very important question." He glanced up at Langdon and then back to Sophie. "Did either of you have anything to do with his death?" "No!" Sophie declared. "Absolutely not." Vernet's face was grim, and he paused, pondering. "Your pictures are being circulated by Interpol. This is how I recognized you. You're wanted for a murder." Sophie slumped. Fache ran an Interpol broadcast already? It seemed the captain was more motivated than Sophie had anticipated. She quickly told Vernet who Langdon was and what had happened inside the Louvre tonight. Vernet looked amazed. "And as your grandfather was dying, he left you a message telling you to find Mr. Langdon?" "Yes. And this key." Sophie laid the gold key on the coffee table in front of Vernet, placing the Priory seal face down. Vernet glanced at the key but made no move to touch it. "He left you only this key? Nothing else? No slip of paper?" Sophie knew she had been in a hurry inside the Louvre, but she was certain she had seen nothing else behind Madonna of the Rocks. "No. Just the key." Vernet gave a helpless sigh. "I'm afraid every key is electronically paired with a ten-digit account number that functions as a password. Without that number, your key is worthless." Ten digits. Sophie reluctantly calculated the cryptographic odds. Over ten billion possible choices.
