Sophie arrived breathless outside the large wooden doors of the Salle des Etats—the
room that housed the Mona Lisa. Before entering, she gazed reluctantly farther down the
hall, twenty yards or so, to the spot where her grandfather's body still lay under the
spotlight.
The remorse that gripped her was powerful and sudden, a deep sadness laced with
guilt. The man had reached out to her so many times over the past ten years, and yet
Sophie had remained immovable—leaving his letters and packages unopened in a bottom
drawer and denying his efforts to see her. He lied to me! Kept appalling secrets! What
was I supposed to do? And so she had blocked him out. Completely.
Now her grandfather was dead, and he was talking to her from the grave.
The Mona Lisa.
She reached for the huge wooden doors, and pushed. The entryway yawned open.
Sophie stood on the threshold a moment, scanning the large rectangular chamber beyond.
It too was bathed in a soft red light. The Salle des Etats was one of this museum's rare
culs-de-sac—a dead end and the only room off the middle of the Grand Gallery. This
door, the chamber's sole point of entry, faced a dominating fifteen-foot Botticelli on the
far wall. Beneath it, centered on the parquet floor, an immense octagonal viewing divan
served as a welcome respite for thousands of visitors to rest their legs while they admired
the Louvre's most valuable asset.
Even before Sophie entered, though, she knew she was missing something. A black
light. She gazed down the hall at her grandfather under the lights in the distance,
surrounded by electronic gear. If he had written anything in here, he almost certainly
would have written it with the watermark stylus.
Taking a deep breath, Sophie hurried down to the well-lit crime scene. Unable to look
at her grandfather, she focused solely on the PTS tools. Finding a small ultraviolet
penlight, she slipped it in the pocket of her sweater and hurried back up the hallway
toward the open doors of the Salle des Etats.
Sophie turned the corner and stepped over the threshold. Her entrance, however, was
met by an unexpected sound of muffled footsteps racing toward her from inside the
chamber. There's someone in here! A ghostly figure emerged suddenly from out of the
reddish haze. Sophie jumped back.
“There you are!” Langdon's hoarse whisper cut the air as his silhouette slid to a stop in
front of her.
Her relief was only momentary. “Robert, I told you to get out of here! If Fache—”
“Where were you?”
“I had to get the black light,” she whispered, holding it up. “If my grandfather left me
a message—”
“Sophie, listen.” Langdon caught his breath as his blue eyes held her firmly. “The
letters P.S. . . . do they mean anything else to you? Anything at all?”
Afraid their voices might echo down the hall, Sophie pulled him into the Salle des
Etats and closed the enormous twin doors silently, sealing them inside. “I told you, the
initials mean Princess Sophie.”
“I know, but did you ever see them anywhere else? Did your grandfather ever use P.S.
in any other way? As a monogram, or maybe on stationery or a personal item?”
The question startled her. How would Robert know that? Sophie had indeed seen the
initials P.S. once before, in a kind of monogram. It was the day before her ninth
birthday. She was secretly combing the house, searching for hidden birthday presents.
Even then, she could not bear secrets kept from her. What did Grand-père get for me this
year? She dug through cupboards and drawers. Did he get me the doll I wanted? Where
would he hide it?
Finding nothing in the entire house, Sophie mustered the courage to sneak into her
grandfather's bedroom. The room was off-limits to her, but her grandfather was
downstairs asleep on the couch.
I'll just take a fast peek!
Tiptoeing across the creaky wood floor to his closet, Sophie peered on the shelves
behind his clothing. Nothing. Next she looked under the bed. Still nothing. Moving to his
bureau, she opened the drawers and one by one began pawing carefully through them.
There must be something for me here! As she reached the bottom drawer, she still had
not found any hint of a doll. Dejected, she opened the final drawer and pulled aside some
black clothes she had never seen him wear. She was about to close the drawer when her
eyes caught a glint of gold in the back of the drawer. It looked like a pocket watch chain,
but she knew he didn't wear one. Her heart raced as she realized what it must be.
A necklace!
Sophie carefully pulled the chain from the drawer. To her surprise, on the end was a
brilliant gold key. Heavy and shimmering. Spellbound, she held it up. It looked like no
key she had ever seen. Most keys were flat with jagged teeth, but this one had a
triangular column with little pockmarks all over it. Its large golden head was in the shape
of a cross, but not a normal cross. This was an even-armed one, like a plus sign.
Embossed in the middle of the cross was a strange symbol—two letters intertwined with
some kind of flowery design.
“P.S.,” she whispered, scowling as she read the letters. Whatever could this be?
“Sophie?” her grandfather spoke from the doorway.
Startled, she spun, dropping the key on the floor with a loud clang. She stared down at
the key, afraid to look up at her grandfather's face. “I . . . was looking for my birthday
present,” she said, hanging her head, knowing she had betrayed his trust.
For what seemed like an eternity, her grandfather stood silently in the doorway.
Finally, he let out a long troubled breath. “Pick up the key, Sophie.”
Sophie retrieved the key.
Her grandfather walked in. “Sophie, you need to respect other people's privacy.”
Gently, he knelt down and took the key from her. “This key is very special. If you had
lost it . . .”
Her grandfather's quiet voice made Sophie feel even worse. “I'm sorry, Grand-père. I
really am.” She paused. “I thought it was a necklace for my birthday.”
He gazed at her for several seconds. “I'll say this once more, Sophie, because it's
important. You need to learn to respect other people's privacy.”
“Yes, Grand-père.”
“We'll talk about this some other time. Right now, the garden needs to be weeded.”
Sophie hurried outside to do her chores.
The next morning, Sophie received no birthday present from her grandfather. She
hadn't expected one, not after what she had done. But he didn't even wish her happy
birthday all day. Sadly, she trudged up to bed that night. As she climbed in, though, she
found a note card lying on her pillow. On the card was written a simple riddle. Even
before she solved the riddle, she was smiling. I know what this is! Her grandfather had
done this for her last Christmas morning.
A treasure hunt!
Eagerly, she pored over the riddle until she solved it. The solution pointed her to
another part of the house, where she found another card and another riddle. She solved
this one too, racing on to the next card. Running wildly, she darted back and forth across
the house, from clue to clue, until at last she found a clue that directed her back to her
own bedroom. Sophie dashed up the stairs, rushed into her room, and stopped in her
tracks. There in the middle of the room sat a shining red bicycle with a ribbon tied to the
handlebars. Sophie shrieked with delight.
“I know you asked for a doll,” her grandfather said, smiling in the corner. “I thought
you might like this even better.”
The next day, her grandfather taught her to ride, running beside her down the
walkway. When Sophie steered out over the thick lawn and lost her balance, they both
went tumbling onto the grass, rolling and laughing.
“Grand-père,” Sophie said, hugging him. “I'm really sorry about the key.”
“I know, sweetie. You're forgiven. I can't possibly stay mad at you. Grandfathers and
granddaughters always forgive each other.”
Sophie knew she shouldn't ask, but she couldn't help it. “What does it open? I never
saw a key like that. It was very pretty.”
Her grandfather was silent a long moment, and Sophie could see he was uncertain how
to answer. Grand-père never lies. “It opens a box,” he finally said. “Where I keep many
secrets.”
Sophie pouted. “I hate secrets!”
“I know, but these are important secrets. And someday, you'll learn to appreciate them
as much as I do.”
“I saw letters on the key, and a flower.”
“Yes, that's my favorite flower. It's called a fleur-de-lis. We have them in the garden.
The white ones. In English we call that kind of flower a lily.”
“I know those! They're my favorite too!”
“Then I'll make a deal with you.” Her grandfather's eyebrows raised the way they
always did when he was about to give her a challenge. “If you can keep my key a secret,
and never talk about it ever again, to me or anybody, then someday I will give it to you.”
Sophie couldn't believe her ears. “You will?”
“I promise. When the time comes, the key will be yours. It has your name on it.”
Sophie scowled. “No it doesn't. It said P.S. My name isn't P.S.!”
Her grandfather lowered his voice and looked around as if to make sure no one was
listening. “Okay, Sophie, if you must know, P.S. is a code. It's your secret initials.”
Her eyes went wide. “I have secret initials?”
“Of course. Granddaughters always have secret initials that only their grandfathers
know.”
“P.S.?”
He tickled her. “Princesse Sophie.”
She giggled. “I'm not a princess!”
He winked. “You are to me.”
From that day on, they never again spoke of the key. And she became his Princess
Sophie.
Inside the Salle des Etats, Sophie stood in silence and endured the sharp pang of loss.
“The initials,” Langdon whispered, eyeing her strangely. “Have you seen them?”
Sophie sensed her grandfather's voice whispering in the corridors of the museum.
Never speak of this key, Sophie. To me or to anyone. She knew she had failed him in
forgiveness, and she wondered if she could break his trust again. P.S. Find Robert
Langdon. Her grandfather wanted Langdon to help. Sophie nodded. “Yes, I saw the
initials P.S. once. When I was very young.”
“Where?”
Sophie hesitated. “On something very important to him.”
Langdon locked eyes with her. “Sophie, this is crucial. Can you tell me if the initials
appeared with a symbol? A fleur-de-lis?”
Sophie felt herself staggering backward in amazement. “But . . . how could you
possibly know that!”
Langdon exhaled and lowered his voice. “I'm fairly certain your grandfather was a
member of a secret society. A very old covert brotherhood.”
Sophie felt a knot tighten in her stomach. She was certain of it too. For ten years she
had tried to forget the incident that had confirmed that horrifying fact for her. She had
witnessed something unthinkable. Unforgivable.
“The fleur-de-lis,” Langdon said, “combined with the initials P.S., that is the
brotherhood's official device. Their coat of arms. Their logo.”
“How do you know this?” Sophie was praying Langdon was not going to tell her that
he himself was a member.
“I've written about this group,” he said, his voice tremulous with excitement.
“Researching the symbols of secret societies is a specialty of mine. They call themselves
the Prieuré de Sion—the Priory of Sion. They're based here in France and attract
powerful members from all over Europe. In fact, they are one of the oldest surviving
secret societies on earth.”
Sophie had never heard of them.
Langdon was talking in rapid bursts now. “The Priory's membership has included
some of history's most cultured individuals: men like Botticelli, Sir Isaac Newton, Victor
Hugo.” He paused, his voice brimming now with academic zeal. “And, Leonardo da
Vinci.”
Sophie stared. “Da Vinci was in a secret society?”
“Da Vinci presided over the Priory between 1510 and 1519 as the brotherhood's
Grand Master, which might help explain your grandfather's passion for Leonardo's work.
The two men share a historical fraternal bond. And it all fits perfectly with their
fascination for goddess iconology, paganism, feminine deities, and contempt for the
Church. The Priory has a well-documented history of reverence for the sacred feminine.”
“You're telling me this group is a pagan goddess worship cult?”
“More like the pagan goddess worship cult. But more important, they are known as the
guardians of an ancient secret. One that made them immeasurably powerful.”
Despite the total conviction in Langdon's eyes, Sophie's gut reaction was one of stark
disbelief. A secret pagan cult? Once headed by Leonardo da Vinci? It all sounded utterly
absurd. And yet, even as she dismissed it, she felt her mind reeling back ten years—to the
night she had mistakenly surprised her grandfather and witnessed what she still could not
accept. Could that explain—?
“The identities of living Priory members are kept extremely secret,” Langdon said,
“but the P.S. and fleur-de-lis that you saw as a child are proof. It could only have been
related to the Priory.”
Sophie realized now that Langdon knew far more about her grandfather than she had
previously imagined. This American obviously had volumes to share with her, but this
was not the place. “I can't afford to let them catch you, Robert. There's a lot we need to
discuss. You need to go!”
Langdon heard only the faint murmur of her voice. He wasn't going anywhere. He was
lost in another place now. A place where ancient secrets rose to the surface. A place
where forgotten histories emerged from the shadows.
Slowly, as if moving underwater, Langdon turned his head and gazed through the
reddish haze toward the Mona Lisa.
The fleur-de-lis . . . the flower of Lisa . . . the Mona Lisa.
It was all intertwined, a silent symphony echoing the deepest secrets of the Priory of
Sion and Leonardo da Vinci.
A few miles away, on the riverbank beyond Les Invalides, the bewildered driver of a
twin-bed Trailor truck stood at gunpoint and watched as the captain of the Judicial Police
let out a guttural roar of rage and heaved a bar of soap out into the turgid waters of the
Seine.
