followed the media coverage closely, some connecting the dots and believing Langdon was now privy to

secret information regarding the Holy Grail—perhaps even its location.

“Look,” Langdon said, “if this is about the Holy Grail, I can assure you I know nothing more than—”

“Don’t insult my intelligence, Mr. Langdon,” the man snapped. “I have no interest in anything so frivolous as

the Holy Grail or mankind’s pathetic debate over whose version of history is correct. Circular arguments

over the semantics of faith hold no interest for me. Those are questions answered only through death.”

The stark words left Langdon confused. “Then what the hell is this about?”

The man paused for several seconds. “As you may know, there exists within this city an ancient portal.”

An ancient portal?

“And tonight, Professor, you will unlock it for me. You should be honored I contacted you—this is the

invitation of your lifetime. You alone have been chosen.”

And you have lost your mind. “I’m sorry, but you’ve chosen poorly,” Langdon said. “I don’t know anything

about any ancient portal.”

“You don’t understand, Professor. It was not I who chose you . . . it was Peter Solomon.”

“What?” Langdon replied, his voice barely a whisper.

“Mr. Solomon told me how to find the portal, and he confessed to me that only one man on earth could

unlock it. And he said that man is you.”

“If Peter said that, he was mistaken . . . or lying.”

“I think not. He was in a fragile state when he confessed that fact, and I am inclined to believe him.”

Langdon felt a stab of anger. “I’m warning you, if you hurt Peter in any—”

“It’s far too late for that,” the man said in an amused tone. “I’ve already taken what I need from Peter

Solomon. But for his sake, I suggest you provide what I need from you. Time is of the essence . . . for both of

you. I suggest you find the portal and unlock it. Peter will point the way.”

Peter? “I thought you said Peter was in ‘purgatory.’”

“As above, so below,” the man said.

Langdon felt a deepening chill. This strange response was an ancient Hermetic adage that proclaimed a belief

in the physical connection between heaven and earth. As above, so below. Langdon eyed the vast room and

wondered how everything had veered so suddenly out of control tonight. “Look, I don’t know how to find

any ancient portal. I’m calling the police.”

“It really hasn’t dawned on you yet, has it? Why you were chosen?”

“No,” Langdon said.

“It will,” he replied, chuckling. “Any moment now.”

Then the line went dead.

Langdon stood rigid for several terrifying moments, trying to process what had just happened.

Suddenly, in the distance, he heard an unexpected sound.

It was coming from the Rotunda.

Someone was screaming.

 CHAPTER 10

Robert Langdon had entered the Capitol Rotunda many times in his life, but never at a full sprint. As he ran

through the north entrance, he spotted a group of tourists clustered in the center of the room. A small boy was

screaming, and his parents were trying to console him. Others were crowding around, and several security

guards were doing their best to restore order.

“He pulled it out of his sling,” someone said frantically, “and just left it there!”

As Langdon drew nearer, he got his first glimpse of what was causing all the commotion. Admittedly, the

object on the Capitol floor was odd, but its presence hardly warranted screaming.

The device on the floor was one Langdon had seen many times. The Harvard art department had dozens of

these—life-size plastic models used by sculptors and painters to help them render the human body’s most

complex feature, which, surprisingly, was not the human face but rather the human hand. Someone left a

mannequin hand in the Rotunda?

Mannequin hands, or handequins as some called them, had articulated fingers enabling an artist to pose the

hand in whatever position he wanted, which for sophomoric college students was often with the middle

finger extended straight up in the air. This handequin, however, had been positioned with its index finger and

thumb pointing up toward the ceiling.

As Langdon drew nearer, though, he realized this handequin was unusual. Its plastic surface was not smooth

like most. Instead, the surface was mottled and slightly wrinkled, and appeared almost . . .

Like real skin.

Langdon stopped abruptly.

Now he saw the blood. My God!

The severed wrist appeared to have been skewered onto a spiked wooden base so that it would stand up. A

wave of nausea rushed over him. Langdon inched closer, unable to breathe, seeing now that the tips of the

index finger and thumb had been decorated with tiny tattoos. The tattoos, however, were not what held

Langdon’s attention. His gaze moved instantly to the familiar golden ring on the fourth finger.

No.

Langdon recoiled. His world began to spin as he realized he was looking at the severed right hand of Peter

Solomon.

CHAPTER 11

Why isn’t Peter answering? Katherine Solomon wondered as she hung up her cell phone. Where is he?

For three years, Peter Solomon had always been the first to arrive for their weekly seven P.M. Sunday-night

meetings. It was their private family ritual, a way to remain connected before the start of a new week, and for

Peter to stay up-to-date on Katherine’s work at the lab.

He’s never late, she thought, and he always answers his phone. To make matters worse, Katherine was still

not sure what she was going to say to him when he did finally arrive. How do I even begin to ask him about

what I found out today?

Her footsteps clicked rhythmically down the cement corridor that ran like a spine through the SMSC. Known

as “The Street,” the corridor connected the building’s five massive storage pods. Forty feet overhead, a

circulatory system of orange ductwork throbbed with the heartbeat of the building—the pulsing sounds of

thousands of cubic feet of filtered air being circulated.

Normally, during her nearly quarter-mile walk to her lab, Katherine felt calmed by the breathing sounds of

the building. Tonight, however, the pulsing had her on edge. What she had learned about her brother today

would have troubled anyone, and yet because Peter was the only family she had in the world, Katherine felt

especially disturbed to think he might be keeping secrets from her.

As far as she knew, he had kept a secret from her only once . . . a wonderful secret that was hidden at the end

of this very hallway. Three years ago, her brother had walked Katherine down this corridor, introducing her

to the SMSC by proudly showing off some of the building’s more unusual items—the Mars meteorite ALH-

84001, the handwritten pictographic diary of Sitting Bull, a collection of wax-sealed Ball jars containing

original specimens collected by Charles Darwin.

At one point, they walked past a heavy door with a small window. Katherine caught a glimpse of what lay

beyond and gasped. “What in the world is that?!”

Her brother chuckled and kept walking. “Pod Three. It’s called Wet Pod. Pretty unusual sight, isn’t it?”

Terrifying is more like it. Katherine hurried after him. This building was like another planet.

“What I really want to show you is in Pod Five,” her brother said, guiding her down the seemingly endless

corridor. “It’s our newest addition. It was built to house artifacts from the basement of the National Museum

of Natural History. That collection is scheduled for relocation here in about five years, which means Pod

Five is sitting empty at the moment.”

Katherine glanced over. “Empty? So why are we looking at it?”

Her brother’s gray eyes flashed a familiar mischief. “It occurred to me that because nobody is using the

space, maybe you could use it.”

“Me?”

“Sure. I thought maybe you could use a dedicated lab space—a facility where you can actually perform some

of the theoretical experiments you’ve been developing for all these years.”

Katherine stared at her brother in shock. “But, Peter, those experiments are theoretical! To actually perform

them would be almost impossible.”

“Nothing is impossible, Katherine, and this building is perfect for you. The SMSC is not just a warehouse of

treasures; it’s one of the world’s most advanced scientific research facilities. We’re constantly taking pieces

from the collection and examining them with the best quantitative technologies money can buy. All the

equipment you could possibly need would be here at your disposal.”

“Peter, the technologies required to run these experiments are—”

“Already in place.” He smiled broadly. “The lab is done.”

Katherine stopped short.

Her brother pointed down the long corridor. “We’re going to see it now.”

Katherine could barely speak. “You . . . you built me a lab?”

“It’s my job. The Smithsonian was established to advance scientific knowledge. As secretary, I must take

that charge seriously. I believe the experiments you’ve proposed have the potential to push the boundaries of

science into uncharted territory.” Peter stopped and looked her squarely in the eyes. “Whether or not you

were my sister, I would feel obliged to support this research. Your ideas are brilliant. The world deserves to

see where they lead.”

“Peter, I can’t possibly—”

“Okay, relax . . . it was my own money, and nobody’s using Pod Five right now. When you’re done with

your experiments, you’ll move out. Besides, Pod Five has some unique properties that will be perfect for

your work.”

Katherine could not imagine what a massive, empty pod might offer that would serve her research, but she

sensed she was about to find out. They had just reached a steel door with boldly stenciled letters:

POD 5

Her brother inserted his key card into a slot and an electronic keypad lit up. He raised his finger to type his

access code, but paused, arching his eyebrows in the same mischievous way he always had as a boy. “You

sure you’re ready?”

She nodded. My brother, always the showman.

“Stand back.” Peter hit the keys.

The steel door hissed loudly open.

Beyond the threshold was only inky blackness . . . a yawning void. A hollow moan seemed to echo out of the

depths. Katherine felt a cold blast of air emanating from within. It was like staring into the Grand Canyon at

night.

“Picture an empty airline hangar waiting for a fleet of Airbuses,” her brother said, “and you get the basic

idea.”

Katherine felt herself take a step backward.

“The pod itself is far too voluminous to be heated, but your lab is a thermally insulated cinder-block room,

roughly a cube, located in the farthest corner of the pod for maximum separation.”

Katherine tried to picture it. A box inside a box. She strained to see into the darkness, but it was absolute.

“How far back?”

“Pretty far . . . a football field would fit easily in here. I should warn you, though, the walk is a little

unnerving. It’s exceptionally dark.”

Katherine peered tentatively around the corner. “No light switch?”

“Pod Five is not yet wired for electricity.”

“But . . . then how can a lab function?”

He winked. “Hydrogen fuel cell.”

Katherine’s jaw dropped. “You’re kidding, right?”

“Enough clean power to run a small town. Your lab enjoys full radio-frequency separation from the rest of

the building. What’s more, all pod exteriors are sealed with photo-resistant membranes to protect the artifacts

inside from solar radiation. Essentially, this pod is a sealed, energy-neutral environment.”

Katherine was starting to comprehend the appeal of Pod 5. Because much of her work centered on

quantifying previously unknown energy fields, her experiments needed to be performed in a location isolated

from any extraneous radiation or “white noise.” This included interference as subtle as “brain radiation” or

“thought emissions” generated by people nearby. For this reason, a university campus or hospital lab

wouldn’t work, but a deserted pod at the SMSC could not have been more perfect.

“Let’s go back and have a look.” Her brother was grinning as he stepped into the vast darkness. “Just follow

me.”

Katherine stalled at the threshold. Over a hundred yards in total darkness? She wanted to suggest a

flashlight, but her brother had already disappeared into the abyss.

“Peter?” she called.

“Leap of faith,” he called back, his voice already fading away. “You’ll find your way. Trust me.”

He’s kidding, right? Katherine’s heart was pounding as she stepped a few feet over the threshold, trying to

peer into the darkness. I can’t see a thing! Suddenly the steel door hissed and slammed shut behind her,

plunging her into total blackness. Not a speck of light anywhere. “Peter?!”

Silence.

You’ll find your way. Trust me.

Tentative, she inched forward blindly. Leap of faith? Katherine could not even see her hand directly in front

of her face. She kept moving forward, but within a matter of seconds, she was entirely lost. Where am I

going?

That was three years ago.

Now, as Katherine arrived at the same heavy metal door, she realized how far she had come since that first

night. Her lab—nicknamed the Cube—had become her home, a sanctuary within the depths of Pod 5.

Exactly as her brother had predicted, she had found her way through the darkness that night, and every day

since—thanks to an ingeniously simple guidance system that her brother had let her discover for herself.

Far more important, her brother’s other prediction had come true as well: Katherine’s experiments had

produced astonishing results, particularly in the last six months, breakthroughs that would alter entire

paradigms of thinking. Katherine and her brother had agreed to keep her results absolutely secret until the

implications were more fully understood. One day soon, however, Katherine knew she would publish some

of the most transformative scientific revelations in human history.

A secret lab in a secret museum, she thought, inserting her key card into the Pod 5 door. The keypad lit up,

and Katherine typed her PIN.

The steel door hissed open.

The familiar hollow moan was accompanied by the same blast of cold air. As always, Katherine felt her pulse

rate start to climb.

Strangest commute on earth.

Steeling herself for the journey, Katherine Solomon glanced at her watch as she stepped into the void.
