〃Was that a pliment？〃
Langdon smiled and moved past her into the dark。 〃Careful on the stairs。〃
He inched slowly into the darkness； keeping one hand on the wall。 The stone felt sharp on his fingertips。 For an instant Langdon recalled the ancient myth of Daedelus； how the boy kept one hand on the wall as he moved through the Minotaur's labyrinth； knowing he was guaranteed to find the end if he never broke contact with the wall。 Langdon moved forward； not entirely certain he wanted to find the end。
The tunnel narrowed slightly； and Langdon slowed his pace。 He sensed Vittoria close behind him。 As the wall curved left； the tunnel opened into a semicircular alcove。 Oddly； there was faint light here。 In the dimness Langdon saw the outline of a heavy wooden door。
〃Uh oh；〃 he said。
〃Locked？〃
〃It was。〃
〃Was？〃 Vittoria arrived at his side。
Langdon pointed。 Lit by a shaft of light ing from within； the door hung ajar 。 。 。 its hinges splintered by a wrecking bar still lodged in the wood。
They stood a moment in silence。 Then； in the dark； Langdon felt Vittoria's hands on his chest； groping； sliding beneath his jacket。
〃Relax； professor；〃 she said。 〃I'm just getting the gun。〃
At that moment； inside the Vatican Museums； a task force of Swiss Guards spread out in all directions。 The museum was dark； and the guards wore U。S。 Marine issue infrared goggles。 The goggles made everything appear an eerie shade of green。 Every guard wore headphones connected to an antennalike detector that he waved rhythmically in front of him…the same devices they used twice a week to sweep for electronic bugs inside the Vatican。 They moved methodically； checking behind statues； inside niches； closets； under furniture。 The antennae would sound if they detected even the tiniest magnetic field。
Tonight； however； they were getting no readings at all。

The interior of Santa Maria del Popolo was a murky cave in the dimming light。 It looked more like a half…finished subway station than a cathedral。 The main sanctuary was an obstacle course of torn…up flooring； brick pallets； mounds of dirt； wheelbarrows； and even a rusty backhoe。 Mammoth columns rose through the floor； supporting a vaulted roof。 In the air； silt drifted lazily in the muted glow of the stained glass。 Langdon stood with Vittoria beneath a sprawling Pinturicchio fresco and scanned the gutted shrine。
Nothing moved。 Dead silence。
Vittoria held the gun out in front of her with both hands。 Langdon checked his watch： 8：04 P。M。 We're crazy to be in here； he thought。 It's too dangerous。 Still he knew if the killer were inside； the man could leave through any door he wanted； making a one…gun outside stakeout totally fruitless。 Catching him inside was the only way 。 。 。 that was； if he was even still here。 Langdon felt guilt…ridden over the blunder that had cost everyone their chance at the Pantheon。 He was in no position to insist on precaution now； he was the one who had backed them into this corner。
Vittoria looked harrowed as she scanned the church。 〃So；〃 she whispered。 〃Where is this Chigi Chapel？〃
Langdon gazed through the dusky ghostliness toward the back of the cathedral and studied the outer walls。 Contrary to mon perception； Renaissance cathedrals invariably contained multiple chapels； huge cathedrals like Notre Dame having dozens。 Chapels were less rooms than they were hollows…semicircular niches holding tombs around a church's perimeter wall。
Bad news； Langdon thought； seeing the four recesses on each side wall。 There were eight chapels in all。 Although eight was not a particularly overwhelming number； all eight openings were covered with huge sheets of clear polyurethane due to the construction； the translucent curtains apparently intended to keep dust off the tombs inside the alcoves。
〃It could be any of those draped recesses；〃 Langdon said。 〃No way to know which is the Chigi without looking inside every one。 Could be a good reason to wait for Oliv…〃
〃Which is the secondary left apse？〃 she asked。
Langdon studied her； surprised by her mand of architectural terminology。 〃Secondary left apse？〃
Vittoria pointed at the wall behind him。 A decorative tile was embedded in the stone。 It was engraved with the same symbol they had seen outside…a pyramid beneath a shining star。 The grime…covered plaque beside it read：
COAT OF ARMS OF ALEXANDER CHIGI
WHOSE TOMB IS LOCATED IN THE
SECONDARY LEFT APSE OF THIS CATHEDRAL
Langdon nodded。 Chigi's coat of arms was a pyramid and star？ He suddenly found himself wondering if the wealthy patron Chigi had been an Illuminatus。 He nodded to Vittoria。 〃Nice work； Nancy Drew。〃
〃What？〃
〃Never mind。 I…〃
A piece of metal clattered to the floor only yards away。 The clang echoed through the entire church。 Langdon pulled Vittoria behind a pillar as she whipped the gun toward the sound and held it there。 Silence。 They waited。 Again there was sound； this time a rustling。 Langdon held his breath。 I never should have let us e in here！ The sound moved closer； an intermittent scuffling； like a man with a limp。 Suddenly around the base of the pillar； an object came into view。
〃Figlio di puttana！〃 Vittoria cursed under her breath； jumping back。 Langdon fell back with her。
Beside the pillar； dragging a half…eaten sandwich in paper； was an enormous rat。 The creature paused when it saw them； staring a long moment down the barrel of Vittoria's weapon； and then； apparently unmoved； continued dragging its prize off to the recesses of the church。
〃Son of a 。 。 。〃 Langdon gasped； his heart racing。
Vittoria lowered the gun； quickly regaining her posure。 Langdon peered around the side of the column to see a workman's lunchbox splayed on the floor； apparently knocked off a sawhorse by the resourceful rodent。
Langdon scanned the basilica for movement and whispered； 〃If this guy's here； he sure as hell heard that。 You sure you don't want to wait for Olivetti？〃
〃Secondary left apse；〃 Vittoria repeated。 〃Where is it？〃
Reluctantly Langdon turned and tried to get his bearings。 Cathedral terminology was like stage directions…totally counterintuitive。 He faced the main altar。 Stage center。 Then he pointed with his thumb backward over his shoulder。
They both turned and looked where he was pointing。
It seemed the Chigi Chapel was located in the third of four recessed alcoves to their right。 The good news was that Langdon and Vittoria were on the correct side of the church。 The bad news was that they were at the wrong end。 They would have to traverse the length of the cathedral； passing three other chapels； each of them； like the Chigi Chapel； covered with translucent plastic shrouds。
〃Wait；〃 Langdon said。 〃I'll go first。〃
〃Forget it。〃
〃I'm the one who screwed up at the Pantheon。〃
She turned。 〃But I'm the one with the gun。〃
In her eyes Langdon could see what she was really thinking 。 。 。 I'm the one who lost my father。 I'm the one who helped build a weapon of mass destruction。 This guy's kneecaps are mine。 。 。
Langdon sensed the futility and let her go。 He moved beside her； cautiously； down the east side of the basilica。 As they passed the first shrouded alcove； Langdon felt taut； like a contestant on some surreal game show。 I'll take curtain number three； he thought。
The church was quiet； the thick stone walls blocking out all hints of the outside world。 As they hurried past one chapel after the other； pale humanoid forms wavered like ghosts behind the rustling plastic。 Carved marble； Langdon told himself； hoping he was right。 It was 8：06 P。M。 Had the killer been punctual and slipped out before Langdon and Vittoria had entered？ Or was he still here？ Langdon was unsure which scenario he preferred。
They passed the second apse； ominous in the slowly darkening cathedral。 Night seemed to be falling quickly now； accentuated by the musty tint of the stained…glass windows。 As they pressed on； the plastic curtain beside them billowed suddenly； as if caught in a draft。 Langdon wondered if someone somewhere had opened a door。
Vittoria slowed as the third niche loomed before them。 She held the gun before her； motioning with her head to the stele beside the a
