Langdon watched dumbfounded as his driver gave the guard an ID. The sentry ran it through an electronic authentication device. The machine flashed green.

"Passenger name?"

"Robert Langdon," the driver replied.

"Guest of?"

"The director."

The sentry arched his eyebrows. He turned and checked a computer printout, verifying it against the data on his computer screen. Then he returned to the window. "Enjoy your stay, Mr. Langdon."

The car shot off again, accelerating another 200 yards around a sweeping rotary that led to the facility’s main entrance. Looming before them was a rectangular, ultramodern structure of glass and steel. Langdon was amazed by the building’s striking transparent design. He had always had a fond love of architecture.

"The Glass Cathedral," the escort offered.

"A church?"

"Hell, no. A church is the one thing we don’t have. Physics is the religion around here. Use the Lord’s name in vain all you like," he laughed, "just don’t slander any quarks or mesons."

Langdon sat bewildered as the driver swung the car around and brought it to a stop in front of the glass building. Quarks and mesons? No border control? Mach 15 jets? Who the hell are these guys? The engraved granite slab in front of the building bore the answer:

CERNConseil Europйen pour la Recherche Nuclйaire

"Nuclear Research?" Langdon asked, fairly certain his translation was correct.

The driver did not answer. He was leaning forward, busily adjusting the car’s cassette player. "This is your stop. The director will meet you at this entrance."

Langdon noted a man in a wheelchair exiting the building. He looked to be in his early sixties. Gaunt and totally bald with a sternly set jaw, he wore a white lab coat and dress shoes propped firmly on the wheelchair’s footrest. Even at a distance his eyes looked lifeless—like two gray stones.
