“Correct.” Langdon still had no idea what this had to do with a pasta pot.
“So it should come as no surprise to you that an early alchemist, Rosicrucian, and mystic like Isaac Newton
also
considered the number thirty-three special.”
“I’m sure he did,” Langdon replied. “Newton was deep into numerology, prophecy, and astrology, but what does—”
“All is revealed at the thirty-third degree.”
Langdon pulled Peter’s ring from his pocket and read the inscription. Then he glanced back at the pot of water. “Sorry, you lost me.”
“Robert, earlier tonight, we all assumed ‘thirty-third degree’ referred to the Masonic degree, and yet when we rotated that ring thirty-three degrees, the cube transformed and revealed a cross. At that moment, we realized the word
degree
was being used in another sense.”
“Yes. Degrees of arc.”
“Exactly. But
degree
has a
third
meaning as well.”
Langdon eyed the pot of water on the stove. “Temperature.”
“Exactly!” she said. “It was right in front of us all night. ‘All is revealed at the thirty-third degree.’ If we bring this pyramid’s temperature to thirty-three degrees . . . it may just reveal something.”
Langdon knew Katherine Solomon was exceptionally bright, and yet she seemed to be missing a rather obvious point. “If I’m not mistaken, thirty-three degrees is almost freezing. Shouldn’t we be putting the pyramid in the freezer?”
Katherine smiled. “Not if we want to follow the recipe written by the great alchemist and Rosicrucian mystic who signed his papers
Jeova Sanctus Unus.
”
Isaacus Neutonuus wrote recipes?
“Robert,
temperature
is the fundamental alchemical catalyst, and it was not always measured in Fahrenheit and Celsius. There are far
older
temperature scales, one of them invented by Isaac—”
“The Newton Scale!” Langdon said, realizing she was right.
“Yes! Isaac Newton invented an entire system of quantifying temperature based entirely on natural phenomena. The temperature of melting
ice was Newton’s base point, and he called it ‘the zeroth degree.’ ” She paused. “I suppose you can guess what degree he assigned the temperature of boiling water—the king of all alchemical processes?”
“Thirty-three.”
“Yes, thirty-three! The thirty-third degree. On the Newton Scale, the temperature of boiling water is thirty-three degrees. I remember asking my brother once why Newton chose that number. I mean, it seemed so random. Boiling water is the most fundamental alchemical process, and he chose thirty-three? Why not a hundred? Why not something more elegant? Peter explained that, to a mystic like Isaac Newton, there was no number more elegant than thirty-three.”
All is revealed at the thirty-third degree.
Langdon glanced at the pot of water and then over at the pyramid.
“
Katherine, the pyramid is made out of solid granite and solid gold. Do you really think boiling water is hot enough to transform it?”
The smile on her face told Langdon that Katherine knew something he did not know. Confidently, she walked over to the island, lifted the gold-capped, granite pyramid, and set it in the strainer. Then she carefully lowered it into the bubbling water. “Let’s find out, shall we?”
High above the National Cathedral, the CIA pilot locked the helicopter in auto-hover mode and surveyed the perimeter of the building and the grounds.
No movement.
His thermal imaging couldn’t penetrate the cathedral stone, and so he couldn’t tell what the team was doing inside, but if anyone tried to slip out, the thermal would pick it up.
It was sixty seconds later that a thermal sensor pinged. Working on the same principle as home-security systems, the detector had identified a strong temperature differential. Usually this meant a human form moving through a cool space, but what appeared on the monitor was more of a thermal cloud, a patch of hot air drifting across the lawn. The pilot found the source, an active vent on the side of Cathedral College.
Probably nothing,
he thought. He saw these kinds of gradients all the time.
Someone cooking or doing laundry.
As he was about to turn away, though, he realized something odd. There were no cars in the parking lot and no lights on anywhere in the building.
He studied the UH-60’s imaging system for a long moment. Then he radioed down to his team leader. “Simkins, it’s probably nothing, but . . .”
“Incandescent temperature indicator!” Langdon had to admit, it was clever.
“It’s simple science,” Katherine said. “Different substances incandesce at different temperatures. We call them thermal markers. Science uses these markers all the time.”
Langdon gazed down at the submerged pyramid and capstone. Wisps of steam were beginning to curl over the bubbling water, although he was not feeling hopeful. He glanced at his watch, and his heart rate accelerated: 11:45 P.M. “You believe something here will
luminesce
as it heats up?”
“Not luminesce, Robert.
Incandesce
. There’s a big difference. Incandescence is caused by
heat,
and it occurs at a specific temperature. For example, when steel manufacturers temper beams, they spray a grid on them with a transparent coating that incandesces at a specific target temperature so they know when the beams are done. Think of a mood ring. Just put it on your finger, and it changes color from body heat.”
“Katherine, this pyramid was built in the 1800s! I can understand a craftsman making hidden release hinges in a stone box, but applying some kind of transparent thermal coating?”
“Perfectly feasible,” she said, glancing hopefully at the submerged pyramid. “The early alchemists used organic phosphors all the time as thermal markers. The Chinese made colored fireworks, and even the Egyptians—” Katherine stopped midsentence, staring intently into the roiling water.
“What?” Langdon followed her gaze into the turbulent water but saw nothing at all.
Katherine leaned in, staring more intently into the water. Suddenly she turned and ran across the kitchen toward the door.
“Where are you going?” Langdon shouted.
She slid to a stop at the kitchen light switch, flipped it off. The lights and exhaust fan went off, plunging the room into total darkness and silence. Langdon turned back to the pyramid and peered through the steam at the capstone beneath the water. By the time Katherine made it back to his side, his mouth had fallen open in disbelief.
Exactly as Katherine had predicted, a small section of the metal capstone was starting to glow beneath the water. Letters were starting to appear, and they were getting brighter as the water heated up.
“Text!” Katherine whispered.
Langdon nodded, dumbstruck. The glowing words were materializing just beneath the engraved inscription on the capstone. It looked like only three words, and although Langdon could not yet read what the words said, he wondered if they would unveil everything they had been looking
for tonight.
The pyramid is a real map,
Galloway had told them,
and it points to a real location.
As the letters shone brighter, Katherine turned off the gas, and the water slowly stopped churning. The capstone now came into focus beneath the water’s calm surface.
Three shining words were clearly legible.
CHAPTER

In the
dim light of the Cathedral College kitchen, Langdon and Katherine stood over the pot of water and stared at the transformed capstone beneath the surface. On the side of the golden capstone, an incandescent message was glowing.
Langdon read the shining text, scarcely able to believe his eyes. He knew the pyramid was rumored to reveal a specific
location
. . . but he had never imagined that the location would be quite
this
specific.
Eight Franklin Square
“A street address,” he whispered, stunned.
Katherine looked equally amazed. “I don’t know what’s there, do you?”
Langdon shook his head. He knew Franklin Square was one of the older sections of Washington, but he wasn’t familiar with the address. He looked at the tip of the capstone, and read downward, taking in the entire text.
The
secret hides
within The Order
Eight Franklin Square
Is there some kind of Order on Franklin Square?
Is there a building that hides the opening to a deep spiral staircase
?
Whether or not there was actually something
buried
at that address, Langdon had no idea. The important issue at this point was that he and Katherine had deciphered the pyramid and now possessed the information required to negotiate Peter’s release.
And not a moment too soon.
The glowing arms on Langdon’s Mickey Mouse watch indicated that they had less than ten minutes to spare.
“Make the call,” Katherine said, motioning to a phone on the wall in the kitchen. “Now!”
The sudden arrival of this moment startled Langdon, and he found himself hesitating.
“Are we sure about this?”
“I most certainly am.”
“I’m not telling him anything until we know Peter is safe.”
“Of course not. You remember the number, right?”
Langdon nodded and made his way over to the kitchen phone. He lifted the receiver and dialed the man’s cell-phone number. Katherine came over and placed her head next to his so she could listen in. As the line began to ring, Langdon prepared himself for the eerie whisper of the man who had tricked him earlier tonight.
Finally, the call connected.
There was no greeting, though. No voice. Only the sound of breathing at the other end.
Langdon waited and then finally spoke. “I have the information you want, but if you want it, you’ll have to give us Peter.”
“Who is this?” a woman’s voice replied.
Langdon jumped. “Robert Langdon,” he said reflexively. “Who are
you
?” For an instant he thought he must have dialed incorrectly.
“Your name is Langdon?”
The woman sounded surprised. “There’s someone here asking for you.”
What?
“I’m sorry,
who
is this?”
“Officer Paige Montgomery with Preferred Security.” Her voice seemed shaky. “Maybe you can help us with this. About an hour ago, my partner responded to a 911 call in Kalorama Heights . . . a possible hostage situation. I lost all contact with her, and so I called backup and came to check the residence. We found my partner dead in the backyard. The home owner was gone, and so we broke in. A cell phone was ringing on the hall table, and I—”
“You’re inside?” Langdon demanded.
“Yes, and the 911 tip . . . was a good one,” the woman stammered. “Sorry if I sound rattled, but my partner’s dead, and we found a man being held here against his will. He’s in bad shape, and we’re working on him now. He’s been asking for two people—one named Langdon and one named Katherine.”
“That’s my brother!” Katherine blurted into the receiver, pressing her head closer to Langdon’s. “I made the 911 call! Is he okay?!”
“Actually, ma’am, he’s . . .” The woman’s voice cracked. “He’s in bad shape. He’s missing his right hand . . .”
“Please,” Katherine urged. “I want to talk to him!”
“They’re working on him at the moment. He’s in and out of consciousness. If you’re anywhere in the area, you should get over here. He obviously wants to see you.”
“We’re about six minutes away!” Katherine said.
“Then I suggest you hurry.” There was a muffled noise in the background, and the woman then returned to the line. “Sorry, it looks like I’m needed. I’ll speak to you when you arrive.”
The line went dead.
CHAPTER
91
Inside Cathedral
College, Langdon and Katherine bounded up the basement stairs and hurried down a darkened hallway looking for a front exit. No longer did they hear the sounds of helicopter blades overhead, and Langdon felt hopeful they could slip out unseen and find their way up to Kalorama Heights to see Peter.
They found him. He’s alive.
Thirty seconds earlier, when they’d hung up with the female security guard, Katherine had hurriedly hoisted the steaming pyramid and capstone out of the water. The pyramid was still dripping when she lowered it into Langdon’s leather bag. Now he could feel the heat radiating through the leather.
Excitement over Peter’s discovery had temporarily trumped any further reflection on the capstone’s glowing message—
Eight Franklin Square—
but there would be time for that once they got to Peter.
As they rounded the corner at the top of the stairs, Katherine stopped short and pointed into a sitting room across the hall. Through the bay window, Langdon could see a sleek black helicopter sitting silent on the lawn. A lone pilot stood beside it, facing away from them and talking on his radio. There was also a black Escalade with tinted windows parked nearby.
Staying in the shadows, Langdon and Katherine moved into the sitting room, and peered out the window to see if they could see the rest of the field team. Thankfully, the huge lawn outside the National Cathedral was empty.
“They must be inside the cathedral,” Langdon said.
“They’re not,” a deep voice said behind them.
