" Why don’t you go talk to the mask makers? See if you can find out the identity of the man in the falcon mask. And ask around a bit at the markets--see if you can find out anything about Angelo de Gradi, too.”
Falco’s relaxed demeanor seemed to cloud over for just a second, but then he smiled lazily and gave her a mock salute. “As you command, Signorina Avogadore. I’ll come by the villa later tonight and let you know what I found out.”
“How about we meet someplace on San Domenico,” Cass said. It wasn’t smart to have Falco strolling the grounds of Agnese’s estate. Just because Siena was going to keep her secret didn’t mean the rest of the staff would be as discreet.
Falco didn’t question her. “Come by Il Mar e la Spada. I’ll even buy you a mug of their finest swill.”
“Deal,” she said as he leaned in to give her a kiss on the cheek. Her eyes focused on the scar beneath his right eye. “What happened?” she asked, running one finger over the slightly raised edges.
“A friend dared me to dive into the canals when I first came to town. I had no idea how shallow they were.” He rubbed at the scar. “Obviously.”
Cass smiled. It sounded like something she might have done as a child. She pressed her lips to Falco’s just for a second, and then slipped quietly out the door. "
