around the Porta Romana, this bridge is his most logical route into the old city.
To the west, in the direction of the Pitti Palace, she could hear sirens and wondered if this was good or bad news. Are they still looking for him? Or have they caught him? As Vayentha strained her ears for some indication as to what was going on, a new sound suddenly became audible—a high-pitched whine somewhere overhead. Her eyes turned instinctively skyward, and she spotted it at once—a small remote-controlled helicopter rising fast over the palace and swooping down over the treetops in the direction of the northeast corner of the Boboli Gardens.
A surveillance drone, Vayentha thought with a surge of hope. If it’s in the air, Brüder has yet to find Langdon.
The drone was approaching fast. Apparently it was surveying the northeast corner of the gardens, the area closest to Ponte Vecchio and Vayentha’s position, which gave her additional encouragement.
If Langdon eluded Brüder, he would definitely be moving in this direction.
As Vayentha watched, however, the drone suddenly dive-bombed out of sight behind the high stone wall. She could hear it hovering in place somewhere below the tree line … apparently having located something of interest.
CHAPTER 29
Seek and ye shall find, Langdon thought, huddled in the dim grotto with Sienna. We sought an exit … and found a dead end.
The amorphous fountain in the center of the cave offered good cover, and yet as Langdon peered out from behind it, he sensed it was too late.
The drone had just swooped down into the walled cul-de-sac, stopping abruptly outside the cavern, where it now hovered at a standstill, only ten feet off the ground, facing the grotto, buzzing intensely like some kind of infuriated insect … awaiting its prey.
Langdon pulled back and whispered the grim news to Sienna. “I think it knows we’re here.”
The drone’s high-pitched whine was nearly deafening inside the cavern, the noise reflecting sharply off the stone walls. Langdon found it hard to believe they were being held hostage by a miniature mechanical helicopter, and yet he knew that trying to run from it was fruitless. So what do we do now? Just wait? His original plan to access what lay behind the little gray door had been a reasonable one, except he hadn’t realized the door was openable only from within.
As Langdon’s eyes adjusted to the grotto’s dark interior, he surveyed their unusual surroundings, wondering if there was any other exit. He saw nothing promising. The interior of the cavern was adorned with sculpted animals and humans, all in various stages of consumption by the strange oozing walls. Dejected, Langdon raised his eyes to the ceiling of stalactites hanging ominously overhead.
A good place to die.
The Buontalenti Grotto—so named for its architect, Bernardo Buontalenti—was arguably the most curious-looking space in all of Florence. Intended as a kind of fun house for young guests at the Pitti Palace, the three-chambered suite of caverns was decorated in a blend of naturalistic fantasy and Gothic excess, composed of what appeared to be dripping concretions and flowing pumice that seemed either to be consuming or exuding the multitude of carved figures. In the days of the Medici, the grotto was accented by having water flow down the interior walls, which served both to cool the space during the hot Tuscan summers and to create the effect of an actual cavern.
Langdon and Sienna were hidden in the first and largest chamber behind an indistinct central fountain. They were surrounded by colorful figures of shepherds, peasants, musicians, animals, and even copies of Michelangelo’s four prisoners, all of which seemed to be struggling to break free of the fluid-looking rock that engulfed them. High above, the morning light filtered down through an oculus in the ceiling, which had once held a giant glass ball filled with water in which bright red carp swam in the sunlight.
Langdon wondered how the original Renaissance visitors here would have reacted at the sight of a real-life helicopter—a fantastical dream of Italy’s own Leonardo da Vinci—hovering outside the grotto.
It was at that moment that the drone’s shrill whine stopped. It hadn’t faded away; rather, it had just … abruptly stopped.
Puzzled, Langdon peered out from behind the fountain and saw that the drone had landed. It was now sitting idle on the gravel plaza, looking much less ominous, especially because the stingerlike video lens on the front was facing away from them, off to one side, in the direction of the little gray door.
