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 fortable。
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 newers 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 puters。
〃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 puter 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 Saunière 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
André Vernet—president of the Paris branch of the Depository Bank of Zurich—lived in a lavish flat above the bank。 Despite his plush acmodations； 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 parison 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 André 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
