To ensure his conversation with Mr. Langdon would not be interrupted, Bezu Fache had turned off his cellular phone. Unfortunately, it was an expensive model equipped with a two-way radio feature, which, contrary to his orders, was now being used by one of his agents to page him.

"Capitaine?" The phone crackled like a walkie-talkie.

Fache felt his teeth clench in rage. He could imagine nothing important enough that Collet would interrupt this surveillance cachée—especially at this critical juncture.

He gave Langdon a calm look of apology. "One moment please." He pulled the phone from his belt and pressed the radio transmission button. "Oui?"

"Capitaine, un agent du Département de Cryptographie est arrivé."

Fache's anger stalled momentarily. A cryptographer? Despite the lousy timing, this was probably good news. Fache, after finding Saunière's cryptic text on the floor, had uploaded photographs of the entire crime scene to the Cryptography Department in hopes someone there could tell him what the hell Saunière was trying to say. If a code breaker had now arrived, it most likely meant someone had decrypted Saunière's message.

"I'm busy at the moment," Fache radioed back, leaving no doubt in his tone that a line had been crossed. "Ask the cryptographer to wait at the command post. I'll speak to him when I'm done."

"Her," the voice corrected. "It's Agent Neveu."

Fache was becoming less amused with this call every passing moment. Sophie Neveu was one of DCPJ's biggest mistakes. A young Parisian déchiffreuse who had studied cryptography in England at the Royal Holloway, Sophie Neveu had been foisted on Fache two years ago as part of the ministry's attempt to incorporate more women into the police force. The ministry's ongoing foray into political correctness, Fache argued, was weakening the department. Women not only lacked the physicality necessary for police work, but their mere presence posed a dangerous distraction to the men in the field. As Fache had feared, Sophie Neveu was proving far more distracting than most.

At thirty-two years old, she had a dogged determination that bordered on obstinate. Her eager espousal of Britain's new cryptologic methodology continually exasperated the veteran French cryptographers above her. And by far the most troubling to Fache was the inescapable universal truth that in an office of middle-aged men, an attractive young woman always drew eyes away from the work at hand.

The man on the radio said, "Agent Neveu insisted on speaking to you immediately, Captain. I tried to stop her, but she's on her way into the gallery."

Fache recoiled in disbelief. "Unacceptable! I made it very clear—"

For a moment, Robert Langdon thought Bezu Fache was suffering a stroke. The captain was mid-sentence when his jaw stopped moving and his eyes bulged. His blistering gaze seemed fixated on something over Langdon's shoulder. Before Langdon could turn to see what it was, he heard a woman's voice chime out behind him.

"Excusez-moi, messieurs."

Langdon turned to see a young woman approaching. She was moving down the corridor toward them with long, fluid strides... a haunting certainty to her gait. Dressed casually in a knee-length, cream-colored Irish sweater over black leggings, she was attractive and looked to be about thirty. Her thick burgundy hair fell unstyled to her shoulders, framing the warmth of her face. Unlike the waifish, cookie-cutter blondes that adorned Harvard dorm room walls, this woman was healthy with an unembellished beauty and genuineness that radiated a striking personal confidence.

To Langdon's surprise, the woman walked directly up to him and extended a polite hand. "Monsieur Langdon, I am Agent Neveu from DCPJ's Cryptology Department." Her words curved richly around her muted Anglo-Franco accent. "It is a pleasure to meet you."

Langdon took her soft palm in his and felt himself momentarily fixed in her strong gaze. Her eyes were olive-green—incisive and clear.

Fache drew a seething inhalation, clearly preparing to launch into a reprimand.

"Captain," she said, turning quickly and beating him to the punch, "please excuse the interruption, but—"

"Ce n'est pas le moment!" Fache sputtered.

"I tried to phone you." Sophie continued in English, as if out of courtesy to Langdon. "But your cell phone wa............
