Page 2 of The Secret of Secrets (Robert Langdon #6)

Robert Langdon awoke peacefully, enjoying the gentle strains of classical music from his phone’s alarm on the bedside table.

Grieg’s “Morning Mood” was probably an obvious choice, but he had always considered it the perfect four minutes of music to start his day.

As the woodwinds swelled, Langdon savored the uncertainty of not being able to recall quite where he was.

Ah yes, he remembered, smiling to himself. The City of a Hundred Spires.

In the dim light, Langdon surveyed the room’s massive arched window, flanked by an antique Edwardian dresser and an alabaster lamp. The plush, hand-knotted carpet was still scattered with rose petals from last night’s turndown service.

Langdon had come to Prague three days earlier and, as he had on previous visits, checked into the Four Seasons Hotel.

When the manager insisted on upgrading Langdon’s reservation to the three-bedroom Royal Suite, he wondered if it was due to his own brand loyalty or, more likely, to the prominence of the woman with whom he was traveling.

“Our most celebrated guests deserve our most celebrated accommodation,” the manager had insisted.

The suite included three separate bedrooms with en suite baths, a living room, a dining room, a grand piano, and a central bay window with a lavish arrangement of red, white, and blue tulips—a welcome gift from the U.S.

embassy. Langdon’s private dressing room offered a pair of brushed wool slippers monogrammed with the initials RL .

Something tells me that’s not Ralph Lauren, he thought, impressed by the personalized touch.

Now, as he luxuriated in bed and listened to the music from his alarm, he felt a tender hand touch his shoulder.

“Robert?” a soft voice whispered.

Langdon rolled over and felt his pulse quicken. She was there, smiling at him, her smoky gray eyes still half-asleep, her long black hair tousled around her shoulders.

“Good morning, beautiful,” he replied.

She reached over and stroked his cheek, the scent of Balade Sauvage still on her wrists.

Langdon admired the elegance of her features. Despite being four years older than Langdon, she was more stunning every time he saw her—the deepening laugh lines, the faint wisps of gray in her dark hair, her playful eyes, and that mesmerizing intellect.

Langdon had known this remarkable woman since his days at Princeton, where she was a young assistant professor while he was an undergrad.

His quiet schoolboy crush on her had gone either unnoticed or unrequited, but they’d enjoyed a flirtatious, platonic friendship ever since.

Even after her professional career skyrocketed, and Langdon became a high-profile professor known throughout the world, the two of them had kept in casual contact.

Timing is everything, Langdon now realized, still marveling at how quickly they had fallen for each other during this spontaneous business trip.

As “Morning Mood” crescendoed into the full orchestration of the theme, he pulled her close with a strong arm, and she nuzzled into his chest. “Sleep okay?” he whispered. “No more bad dreams?”

She shook her head and sighed. “I’m so embarrassed. That was awful.”

Earlier in the night, she had awoken in terror from an exceptionally vivid nightmare, and Langdon had needed to comfort her for nearly an hour before she could get back to sleep.

The dream’s unusual intensity, Langdon assured her, had been the result of her ill-advised nightcap of Bohemian absinthe, which Langdon had always believed should be served with a disclaimer: Popular during the Belle Epoque for its hallucinogenic properties.

“Never again,” she assured him.

Langdon reached over and turned off the music. “Close your eyes. I’ll be back in time for breakfast.”

“Stay with me,” she teased, holding him. “You can skip one day of swimming.”

“Not if you want me to remain a chiseled younger man,” he said, sitting up with a lopsided grin. Each morning, Langdon had jogged the three kilometers to Strahov Swimming Center for his morning laps.

“It’s dark out,” she pressed. “Can’t you just swim here?”

“In the hotel pool?”

“Why not? It’s water.”

“It’s tiny. Two strokes and I’m finished.”

“There’s a joke there, Robert, but I’ll be kind.”

Langdon smiled. “Funny girl. Go back to sleep, and I’ll meet you for breakfast.”

She pouted, threw a pillow at him, and rolled over.

Langdon donned his faculty-issue Harvard sweats and headed for the door, choosing to take the stairs rather than the suite’s cramped private elevator.

Downstairs, he strode through the elegant hallway that connected the hotel’s Baroque riverfront annex with the building’s lobby. Along the way, he passed an elegant display case marked Prague Happenings , featuring a series of framed posters announcing this week’s concerts, tours, and lectures.

The glossy poster at the center made him smile.

Charles University Lecture Series

Welcomes to Prague Castle

Internationally Acclaimed

Noetic Scientist

Dr. Katherine Solomon

Good morning, beautiful, he mused, admiring the headshot of the woman he had just kissed upstairs.

Katherine’s lecture last night had been standing room only, no small feat considering she had spoken in Prague Castle’s legendary Vladislav Hall—a cavernous, vaulted chamber used during the Renaissance to host indoor jousting competitions with knights and horses in full regalia.

The lecture series was one of Europe’s most respected and always drew accomplished speakers and enthusiastic audiences from around the world. Last night had been no exception, and the packed hall erupted with applause when Katherine was introduced.

“Thank you, everyone,” Katherine said, taking the stage with a confident calm.

She wore a white cashmere sweater and designer slacks that fit her flawlessly.

“I’d like to begin tonight by answering the one question I am asked almost every day.

” She grinned and pulled the microphone off its stand. “What the hell is noetic science ?!”

A wave of laughter rolled through the hall as the audience settled in.

“Simply stated,” Katherine began, “noetic science is the study of human consciousness . Contrary to what many believe, consciousness research is not a new science—it is, in fact, the oldest science on earth. Since the dawn of history, we have sought answers to the enduring mysteries of the human mind…the nature of consciousness and of the soul. And for centuries, we have explored these questions primarily through…the lens of religion .”

Katherine stepped off the stage, moving toward the front row of attendees. “And speaking of religion, ladies and gentlemen, I couldn’t help but notice that we have in the audience with us tonight a world-renowned scholar of religious symbology, Professor Robert Langdon.”

Langdon heard murmurs of excitement in the crowd. What the hell is she doing?!

“Professor,” she said, arriving before him with a smile, “I wonder if we might avail ourselves of your expertise for a moment? Would you mind standing up?”

Langdon politely stood, quietly shooting her a you’ll-pay-for-this grin.

“I’m curious, Professor…what is the most common religious symbol on earth?”

The answer was simple, and either Katherine had read Langdon’s article on the topic and knew what was coming, or she was about to be very disappointed.

Langdon accepted the microphone and turned to face the sea of eager faces, dimly lit by chandeliers hanging on ancient iron chains.

“Good evening, everyone,” he said, his deep baritone booming through the speakers.

“And thank you to Dr. Solomon for putting me on the spot with no warning whatsoever.”

The audience clapped.

“All right then,” he said, “the world’s most common religious symbol? Does anyone have a guess?”

A dozen hands went up.

“Excellent,” Langdon said. “Any guesses that are not the crucifix?”

Every single hand went down.

Langdon chuckled. “It’s true that the crucifix is extremely common, but it is also a uniquely Christian symbol. There is, in fact, one universal symbol that appears in the artwork of every religion in history.”

The audience exchanged puzzled looks.

“You’ve all seen it many times,” Langdon coaxed. “Perhaps on the Egyptian Horakhty stela?”

He paused.

“How about the Buddhist Kanishka casket? Or the famed Christ Pantocrator?”

Silence. Dead stares.

Oh boy, Langdon thought. Definitely a science crowd.

“It also appears in hundreds of the most celebrated Renaissance paintings—Leonardo da Vinci’s second Virgin of the Rocks, Fra Angelico’s The Annunciation, Giotto’s Lamentation, Titian’s Temptation of Christ, and countless depictions of Madonna and Child …?”

Still nothing.

“The symbol I’m referring to,” he said, “is the halo .”

Katherine smiled, apparently knowing this would be his answer.

“The halo,” Langdon continued, “is the disk of light that appears over the head of an enlightened being. In Christianity, halos hover over Jesus, Mary, and the saints. Going further back, a sun disk hovered over the ancient Egyptian god Ra, and in Eastern religions a nimbus halo appeared over the Buddha and the Hindu deities.”

“Wonderful, thank you, Professor,” Katherine said, reaching for the microphone, but Langdon ignored her and pivoted away playfully—a touch of payback. Never ask an historian a question you don’t want answered fully.

“I should add,” Langdon said as the crowd laughed appreciatively, “that halos come in all shapes, sizes, and artistic representations. Some are solid gold disks, some are transparent, and some are even square. Ancient Jewish scripture describes Moses’s head as being surrounded by a ‘hila’—the Hebrew word for ‘halo’ or ‘emanation of light.’ Certain specialized forms of halos have rays of light emanating from them…

glowing spines that radiate outward in all directions. ”

Langdon turned back to Katherine with a devious smile. “Perhaps Dr. Solomon knows what this type of halo is called?” He tipped the mic to her.
