"Fleet Street?" Langdon asked, eyeing Teabing in the back of the limo. There's a crypt on FleetStreet? So far, Leigh was being playfully cagey about where he thought they would find the"knight's tomb," which, according to the poem, would provide the password for opening thesmaller cryptex.

　　Teabing grinned and turned to Sophie. "Miss Neveu, give the Harvard boy one more shot at theverse, will you?"Sophie fished in her pocket and pulled out the black cryptex, which was wrapped in the vellum.

　　Everyone had decided to leave the rosewood box and larger cryptex behind in the plane'sstrongbox, carrying with them only what they needed, the far more portable and discreet blackcryptex. Sophie unwrapped the vellum and handed the sheet to Langdon.

　　Although Langdon had read the poem several times onboard the jet, he had been unable to extractany specific location. Now, as he read the words again, he processed them slowly and carefully,hoping the pentametric rhythms would reveal a clearer meaning now that he was on the ground.

　　In London lies a knight a Pope interred.

　　His labor's fruit a Holy wrath incurred.

　　You seek the orb that ought be on his tomb.

　　It speaks of Rosy flesh and seeded womb.

　　The language seemed simple enough. There was a knight buried in London. A knight who laboredat something that angered the Church. A knight whose tomb was missing an orb that should bepresent. The poem's final reference—Rosy flesh and seeded womb—was a clear allusion to MaryMagdalene, the Rose who bore the seed of Jesus.

　　Despite the apparent straightforwardness of the verse, Langdon still had no idea who this knightwas or where he was buried. Moreover, once they located the tomb, it sounded as if they would besearching for something that was absent. The orb that ought be on his tomb?

　　"No thoughts?" Teabing clucked in disappointment, although Langdon sensed the Royal Historianwas enjoying being one up. "Miss Neveu?"She shook her head.

　　"What would you two do without me?" Teabing said. "Very well, I will walk you through it. It'squite simple really. The first line is the key. Would you read it please?"Langdon read aloud. " 'In London lies a knight a Pope interred.' ""Precisely. A knight a Pope interred." He eyed Langdon. "What does that mean to you?"Langdon shrugged. "A knight buried by a Pope? A knight whose funeral was presided over by aPope?"Teabing laughed loudly. "Oh, that's rich. Always the optimist, Robert. Look at the second line.

　　This knight obviously did something that incurred the Holy wrath of the Church. Think again.

　　Consider the dynamic between the Church and the Knights Templar. A knight a Pope interred?""A knight a Pope killed?" Sophie asked.

　　Teabing smiled and patted her knee. "Well done, my dear. A knight a Pope buried. Or killed."Langdon thought of the notorious Templar round-up in 1307—unlucky Friday thethirteenth—when Pope Clement killed and interred hundreds of Knights Templar. "But there mustbe endless graves of 'knights killed by Popes.' ""Aha, not so! "Teabing said. "Many of them were burned at the stake and tossed unceremoniouslyinto the Tiber River. But this poem refers to a tomb. A tomb in London. And there are few knightsburied in London." He paused, eyeing Langdon as if waiting for light to dawn. Finally he huffed.

　　"Robert, for heaven's sake! The church built in London by the Priory's military arm—the KnightsTemplar themselves!""The Temple Church?" Langdon drew a startled breath. "It has a crypt?""Ten of the most frightening tombs you will ever see."Langdon had never actually visited the Temple Church, although he'd come across numerousreferences in his Priory research. Once the epicenter of all Templar/Priory activities in the UnitedKingdom, the Temple Church had been so named in honor of Solomon's Temple, from which theKnights Templar had extracted their own title, as well as the Sangreal documents that gave them alltheir influence in Rome. Tales abounded of knights performing strange, secretive rituals within theTemple Church's unusual sanctuary. "The Temple Church is on Fleet Street?""Actually, it's just off Fleet Street on Inner Temple Lane." Teabing looked mischievous. "I wantedto see you sweat a little more before I gave it away.""Thanks.""Neither of you has ever been there?"Sophie and Langdon shook their heads.

　　"I'm not surprised," Teabing said. "The church is hidden now behind much larger buildings. Fewpeople even know it's there. Eerie old place. The architecture is pagan to the core."Sophie looked surprised. "Pagan?""Pantheonically pagan!" Teabing exclaimed. "The church is round. The Templars ignored thetraditional Christian cruciform layout and built a perfectly circular church in honor of the sun." Hiseyebrows did a devilish dance. "A not so subtle howdy-do to the boys in Rome. They might as wellhave resurrected Stonehenge in downtown London."Sophie eyed Teabing. "What about the rest of the poem?"The historian's mirthful air faded. "I'm not sure. It's puzzling. We will need to examine each of theten tombs carefully. With luck, one of them will have a conspicuously absent orb."Langdon realized how close they really were. If the missing orb revealed the password, they wouldbe able to open the second cryptex. He had a hard time imagining what they might find inside.

　　Langdon eyed the poem again. It was like some kind of primordial crossword puzzle. A five-letterword that speaks of the Grail? On the plane, they had already tried all the obviouspasswords—GRAIL, GRAAL, GREAL, VENUS, MARIA, JESUS, SARAH—but the cylinder hadnot budged. Far too obvious. Apparently there existed some other five-letter reference to the Rose'sseeded womb. The fact that the word was eluding a specialist like Leigh Teabing signified toLangdon that it was no ordinary Grail reference.

　　"Sir Leigh?" Rémy called over his shoulder. He was watching them in the rearview mirror throughthe open divider. "You said Fleet Street is near Blackfriars Bridge?""Yes, take Victoria Embankment.""I'm sorry. I'm not sure where that is. We usually go only to the hospital."Teabing rolled............
