Inferno: (Robert Langdon Book 4)

retaining wall, nearly bumping into Sienna and Langdon. Both figures were wearing black, and for one frightening instant, Sienna thought they were the soldiers she had encountered at the apartment building. As they passed, though, she saw they were only tourists—Italian, she guessed, from all the stylish black leather.
    Having an idea, Sienna caught one of the tourists’ arms and smiled up at him as warmly as possible. “Può dirci dov’è la Galleria del costume?” she asked in rapid Italian, requesting directions to the palace’s famed costume gallery. “Io e mio fratello siamo in ritardo per una visita privata.” My brother and I are late for a private tour.
    “Certo!” The man grinned at them both, looking eager to help. “Proseguite dritto per il sentiero!” He turned and pointed west, along the retaining wall, directly away from whatever Langdon had been looking at.
    “Molte grazie!” Sienna chirped with another smile as the two men headed off.
    Langdon gave Sienna an impressed nod, apparently understanding her motives. If the police began questioning tourists, they might hear that Langdon and Sienna were headed for the costume gallery, which, according to the map on the wall before them, was at the far western end of the palace … as far as possible from the direction in which they were now headed.
    “We need to get to that path over there,” Langdon said, motioning across an open plaza toward a walkway that ran down another hill, away from the palace. The peastone walkway was sheltered on the uphill side by massive hedges, providing plenty of cover from the authorities now descending the hill, only a hundred yards away.
    Sienna calculated that their chances of getting across the open area to the sheltered path were very slim. Tourists were gathering there, watching the police with curiosity. The faint thrum of the drone became audible again, approaching in the distance.
    “Now or never,” Langdon said, grabbing her hand and pulling her with him out into the open plaza, where they began winding through the crowd of gathering tourists. Sienna fought the urge to break into a run, but Langdon held firmly on to her, walking briskly but calmly through the throng.
    When they finally reached the opening to the pathway, Sienna glanced back over her shoulder to see if they had been detected. The only police officers in sight were all facing the other way, their eyes turned skyward toward the sound of the incoming drone.
    She faced front and hurried with Langdon down the path.
    Before them now, the skyline of old Florence poked above the trees, visible directly ahead in the distance. She saw the red-tiled cupola of the Duomo and the green, red, and white spire of Giotto’s bell tower. For an instant, she could also make out the crenellated spire of the Palazzo Vecchio—their seemingly impossible destination—but as they descended the pathway, the high perimeter walls blotted out the view, engulfing them again.
    By the time they reached the bottom of the hill, Sienna was out of breath and wondering if Langdon had any idea where they were going. The path led directly into a maze garden, but Langdon confidently turned left into a wide gravel patio, which he skirted, staying behind a hedge in the shadows of the overhanging trees. The patio was deserted, more of an employee parking lot than a tourist area.
    “Where are we going?!” Sienna finally asked, breathless.
    “Almost there.”
    Almost where? The entire patio was enclosed by walls that were at least three stories tall. The only exit Sienna saw was a vehicle gateway on the left, which was sealed by a massive wrought-iron grate that looked like it dated back to the original palace in the days of marauding armies. Beyond the barricade, she could see police gathered in the Piazza dei Pitti.
    Staying along the perimeter vegetation, Langdon pushed onward, heading directly for the wall in front of them. Sienna scanned the sheer face for any open doorway, but all she saw was a niche containing what had to be the most hideous statue she had ever seen.
    Good God, the Medici could afford any artwork on earth, and they chose this?
    The statue before them depicted an obese, naked dwarf straddling a giant turtle. The dwarf’s testicles were squashed against the turtle’s shell, and the turtle’s mouth was dribbling water, as if he were ill.
    “I know,” Langdon said, without breaking stride. “That’s Braccio di Bartolo —a famous court dwarf. If
