know. My heart is pounding. But remember our purpose. Preservation of the site is important above all else.”
This received a round of nods and murmurs of assent. Geena took a moment to run down a mental checklist. Plastic sheeting had been hung to cover the door they had used to access these stairs. A preservation team waited in Petrarch’s library for a signal, in case their entry into this new subterranean level caused rapid deterioration of anything they might discover. Sabrina was filming.
She opened the door.
Maglite beams illuminated the room beyond. Her heart thundered in her chest and her face felt flushed. With Nico so near she felt his excitement, and it addedto her own in a manner not much different from the way they shared arousal during lovemaking.
Yet as she scanned this new chamber with her torchlight, she could not help but feel a momentary disappointment. Aside from three thin marble columns at its center, it had no trace of architectural style, nor any visible art. Unless there were passages into connecting rooms, the chamber measured only forty feet or less in diameter. It had nothing of beauty or adornment about it, and reminded her more of a dungeon than of the intricate stonework of Petrarch’s library above them.
“What is this place?” Nico asked.
Geena led them in and the small exploratory group fanned out. A number of vertical stone obelisks were spaced at what appeared to be equal intervals around the chamber, which she now realized was round. That facet in itself was interesting. Why go to the trouble of building a perfectly circular room without making some effort toward aesthetics?
“How many of these obelisks are there?” she called out.
To her surprise, it was Finch who answered first. “Ten.”
She shone her light at the nearest one and saw that the black stone was engraved with the same Roman numeral as they had encountered on the door to the chamber.
“Do they all have the same number on them?” she asked, sweeping the light around, picking up glimpses of obelisks and the faces of her team. “Or are they different?”
“This one is the same,” Domenic called from across the chamber.
“Do you think—” Geena began.
But Domenic beat her to it. “It could be some kind of secret meeting place for the Council of Ten.”
Geena nodded, though she doubted anyone saw her. From the early 14th century, Venice had been primarily controlled by a secretive group of ten men, from whose number the next Doge would always be chosen. The group had been created to oversee the security of the Republic and protect the government from corruption or rebellion, but grew in power until, by the mid-15th century, the Council of Ten had total control over Venice.
But there had been many members of the Ten over the centuries, and many of their burial places were well recorded. If these obelisks were the tombs of Council members, the obvious question was, why
these
ten?
A ripple of sharp curiosity ran up the back of her neck, but it was not her own. Nico had found something. She turned, searching for him with her light. The others’ Maglite beams strobed the dark chamber.
“You’re not going to believe this,” Domenic said, his flashlight illuminating a section of the stone floor.
As Geena approached, she saw what had made such an impact on him. In the space between two of the obelisks, an almost perfectly round disk of granite had been set into the stone floor. Whether by design or over the ages, it had sunk slightly so that it sat an inch or two below the level of the rest of the floor.
“It’s almost like a cork,” Finch said, coming up behind her.
“Precisely what I was thinking,” Domenic said.
Geena glanced at them and then stared down at the granite disk, her mind racing. She knelt and ran her fingers along the edges of the stones surrounding it. Theyhad been carefully hewn to create a circular space to fit the disk.
“How did they accomplish it?” she muttered to
