When the building was first unveiled in 1997, The New Yorker hailed its architect, Frank Gehry, as having designed “a fantastic dream ship of undulating form in a cloak of titanium,” while other critics around the world gushed, “The greatest building of our time!” “Mercurial brilliance!” “An astonishing architectural feat!”

Since the museum’s debut, dozens of other “deconstructivist” buildings had been erected—the Disney Concert Hall in Los Angeles, BMW World in Munich, and even the new library at Langdon’s own alma mater. Each featured radically unconventional design and construction, and yet Langdon doubted any of them could compete with the Bilbao Guggenheim for its sheer shock value.

As Langdon approached, the tiled facade seemed to morph with each step, offering a fresh personality from every angle. The museum’s most dramatic illusion now became visible. Incredibly, from this perspective, the colossal structure appeared to be quite literally floating on water, adrift on a vast “infinity” lagoon that lapped against the museum’s outer walls.

Langdon paused a moment to marvel at the effect and then set out to cross the lagoon via the minimalist footbridge that arched over the glassy expanse of water. He was only halfway across when a loud hissing noise startled him. It was emanating from beneath his feet. He stopped short just as a swirling cloud of mist began billowing out from beneath the walkway. The thick veil of fog rose around him and then tumbled outward across the lagoon, rolling toward the museum and engulfing the base of the entire structure.

The Fog Sculpture, Langdon thought.

He had read about this work by Japanese artist Fujiko Nakaya. The “sculpture” was revolutionary in that it was constructed out of the medium of visible air, a wall of fog that materialized and dissipated over time; and because the breezes and atmospheric conditions were never identical one day to the next, the sculpture was different every time it appeared.

The bridge stopped hissing, and Langdon watched the wall of fog settle silently across the lagoon, swirling and creeping as if it had a mind of its own. The effect was both ethereal and disorienting. The entire museum now appeared to be hovering over the water, resting weightlessly on a cloud—a ghost ship lost at sea.

Just as Langdon was about to set out again, the tranquil surface of the water was shattered by a series of small eruptions. Suddenly five flaming pillars of fire shot skyward out of the lagoon, thundering steadily like rocket engines that pierced the mist-laden air and threw brilliant bursts of light across the museum’s titanium tiles.

Langdon’s own architectural taste tended more to the classical stylings of museums like the Louvre or the Prado, and yet as he watched the fog and flame hover above the lagoon, he could think of no place more suitable than this ultramodern museum to host an event thrown by a man who loved art and innovation, and who glimpsed the future so clearly.

Now, walking through the mist, Langdon pressed on to the museum’s entrance—an ominous black hole in the reptilian structure. As he neared the threshold, Langdon had the uneasy sense that he was entering the mouth of a dragon.

CHAPTER 2

NAVY ADMIRAL LUIS Ávila was seated on a bar stool inside a deserted pub in an unfamiliar town. He was drained from his journey, having just flown into this city after a job that had taken him many thousands of miles in twelve hours. He took a sip of his second tonic water and stared at the colorful array of bottles behind the bar.

Any man can stay sober in a desert, he mused, but only the loyal can sit in an oasis and refuse to part his lips.

Ávila had not parted his lips for the devil in almost a year. As he eyed his reflection in the mirrored bar, he permitted himself a rare moment of contentment with the image looking back at him.

Ávila was one of those fortunate Mediterranean men for whom aging seemed to be more an asset than a liability. Over the years, his stiff black stubble had softened to a distinguished salt-and-pepper beard, his fiery dark eyes had relaxed to a serene confidence, and his taut olive skin was now sun-drenched and creased, giving him the aura of a man permanently squinting out to sea.

Even at sixty-three years old, his body was lean and toned, an impressive physique further enhanced by his tailored uniform. At the moment, Ávila was clothed in his full-dress navy whites—a regal-looking livery consisting of a double-breasted white jacket, broad black shoulder boards, an imposing array of service medals, a starched white standing-collar shirt, and silk-trimmed white slacks.

The Spanish Armada may not be the most potent navy on earth anymore, but we still know how to dress an officer.

The admiral had not donned this uniform in years—but this was a special night, and earlier, as he walked the streets of this unknown town, he had enjoyed the favorable looks of women as well as the wide berth afforded him by men.

Everyone respects those who live by a code.

“¿Otra tónica?” the pretty barmaid asked. She was in her thirties, was full-figured, and had a playful smile.

Ávila shook his head. “No, gracias.”

This pub was entirely empty, and Ávila could feel the barmaid’s eyes admiring him. It felt good to be seen again. I have returned from the abyss.

The horrific event that all but destroyed Ávila’s life five years ago would forever lurk in the recesses of his mind—a single deafening instant in which the earth had opened up and swallowed him whole.

Cathedral of Seville.

Easter morning.

The Andalusian sun was streaming through stained glass, splashing kaleidoscopes of color in radiant bursts across the cathedral’s stone interior. The pipe organ thundered in joyous celebration as thousands of worshippers celebrated the miracle of resurrection.
