The Da Vinci Code

"We’re trying to find a tomb in London."

Gettum looked dubious. "We’ve got about twenty thousand of them. Can you be a little more specific?"

"It’s the tomb of a knight.We don’t have a name."

"A knight. That tightens the net substantially. Much less common."

"We don’t have much information about the knight we’re looking for," Sophie said," but this is what we know." She produced a slip of paper on which she had written only the first two lines of the poem.

Hesitant to show the entire poem to an outsider, Langdon and Sophie had decided to share just the first two lines, those that identified the knight. Compartmentalized cryptography, Sophie had called it. When an intelligence agency intercepted a code containing sensitive data, cryptographers each worked on a discrete section of the code. This way, when they broke it, no single cryptographer possessed the entire deciphered message.

In this case, the precaution was probably excessive; even if this librarian saw the entire poem, identified the knight’s tomb, and knew what orb was missing, the information was useless without the cryptex.

Gettum sensed an urgency in the eyes of this famed American scholar, almost as if his finding this tomb quickly were a matter of critical importance. The green-eyed woman accompanying him also seemed anxious.

Puzzled, Gettum put on her glasses and examined the paper they had just handed her.

In London lies a knight a Pope interred.

His labor’s fruit a Holy wrath incurred.

She glanced at her guests. "What is this? Some kind of Harvard scavenger hunt?" Langdon’s laugh sounded forced. "Yeah, something like that." Gettum paused, feeling she was not getting the whole story. Nonetheless, she felt intrigued and found herself pondering the verse carefully. "According to this rhyme, a knight did something that incurred displeasure with God, and yet a Pope was kind enough to bury him in London."

Langdon nodded. "Does it ring any bells?"

Gettum moved toward one of the workstations. "Not offhand, but let’s see what we can pull up in the database."

Over the past two decades, King’s College Research Institute in Systematic Theology had used optical character recognition software in unison with linguistic translation devices to digitize and catalog an enormous collection of texts – encyclopedias of religion, religious biographies, sacred scriptures in dozens of languages, histories, Vatican letters, diaries of clerics, anything at all that qualified as writings on human spirituality. Because the massive collection was now in the form of bits and bytes rather than physical pages, the data was infinitely more accessible.

Settling into one of the workstations, Gettum eyed the slip of paper and began typing. "To begin, we’ll run a straight Boolean with a few obvious keywords and see what happens."

"Thank you."

Gettum typed in a few words:

LONDON, KNIGHT, POPE

As she clicked the SEARCH button, she could feel the hum of the massive mainframe downstairs scanning data at a rate of 500 MB/sec. "I’m asking the system to show us any documents whose complete text contains all three of these keywords. We’ll get more hits than we want, but it’s a good place to start."

The screen was already showing the first of the hits now.

Painting the Pope. The Collected Portraits of Sir Joshua Reynolds. London University Press.

Gettum shook her head. "Obviously not what you’re looking for." She scrolled to the next hit.

The London Writings of Alexander Pope by G. Wilson Knight.

Again she shook her head.

As the system churned on, the hits came up more quickly than usual. Dozens of texts appeared, many of them referencing the eighteenth-century British writer Alexander Pope, whose counter religious, mock-epic poetry apparently contained plenty of references to knights and London.

Gettum shot a quick glance to the numeric field at the bottom of the screen. This computer, by calculating the current number of hits and multiplying by the percentage of the database left to search, provided a rough guess of how much information would be found. This particular search looked like it was going to return an obscenely large amount of data.

Estimated number of total hits: 2, 692

"We need to refine the parameters further," Gettum said, stopping the search. "Is this all the information you have regarding the tomb? There’s nothing else to go on?"

Langdon glanced at Sophie Neveu, looking uncertain.

This is no scavenger hunt, Gettum sensed. She had heard the whisperings of Robert Langdon’s experience in Rome last year. This American had been granted access to the most secure library on earth – the Vatican Secret Archives. She wondered what kinds of secrets Langdon might have learned inside and if his current desperate hunt for a mysterious London tomb might relate to information he had gained within the Vatican. Gettum had been a librarian long enough to know the most common reason people came to London to look for knights. The Grail.

Gettum smiled and adjusted her glasses. "You are friends with Leigh Teabing, you are in England, and you are looking for a knight." She folded her hands. "I can only assume you are on a Grail quest."

Langdon and Sophie exchanged startled looks.

Gettum laughed. "My friends, this library is a base camp for Grail seekers. Leigh Teabing among them. I wish I had a shilling for every time I’d run searches for the Rose, Mary Magdalene, Sangreal, Merovingian, Priory of Sion, et cetera, et cetera. Everyone loves a conspiracy." She took off her glasses and eyed them. "I need more information."

In the silence, Gettum sensed her guests’ desire for discretion was quickly being outweighed by their eagerness for a fast result.

"Here," Sophie Neveu blurted. "This is everything we know." Borrowing a pen from Langdon, she wrote two more lines on the slip of paper and handed it to Gettum.

You seek the orb that ought be on his tomb. It speaks of Rosy flesh and seeded womb.

Gettum gave an inward smile. The Grail indeed, she thought, noting the references to the Rose and her seeded womb. "I can help you," she said, looking up from the slip of paper. "Might I ask where this verse came from? And why you are seeking an orb?"

"You might ask," Langdon said, with a friendly smile," but it’s a long story and we have very little time."

"Sounds like a polite way of saying "mind your own business.""

"We would be forever in your debt, Pamela," Langdon said, "if you could find out who this knight is and where he is buried."

"Very well," Gettum said, typing again. "I’ll play along. If this is a Grail-related issue, we should cross-reference against Grail keywords. I’ll add a proximity parameter and remove the title weighting. That will limit our hits only to those instances of textual keywords that occur near aGrail-related word."

Search for: KNIGHT, LONDON, POPE, TOMB

Within 100 word proximity of: GRAIL, ROSE, SANGREAL, CHALICE

"How long will this take?" Sophie asked.

"A few hundred terabytes with multiple cross-referencing fields?" Gettum’s eyes glimmered as she clicked the SEARCH key. "A mere fifteen minutes."

Langdon and Sophie said nothing, but Gettum sensed this sounded like an eternity to them.

"Tea?" Gettum asked, standing and walking toward the pot she had made earlier. "Leigh always loves my tea."

CHAPTER 93

London’s Opus Dei Centre is a modest brick building at 5 Orme Court, overlooking the North Walk at Kensington Gardens. Silas had never been here, but he felt a rising sense of refuge and asylum as he approached the building on foot. Despite the rain, Remy had dropped him off a short distance away in order to keep the limousine off the main streets. Silas didn’t mind the walk. The rain was cleansing.
