" All finished. Don’t look, though. You and your man must be surprised together.”
“Siena,” Cass cautioned quickly. “He is not my man.”
“If he looked at me the way he looks at you, I would not be so quick to denounce him,” Siena teased, her eyes brightening in a way that reminded Cass quite a bit of Feliciana. She stepped back from Cass and gave a satisfied nod. “And now--for me. Shall I change into something more revealing as well?”
Cass realized that Siena intended to accompany her. “I--I think it’s better if Falco and I go off on our own.”
Siena’s flawless skin paled. “Unchaperoned? But that’s unacceptable. If your aunt found out, she’d run me out of the villa, if she didn’t kill me first.”
So true. Cass could just hear Agnese shrieking about what Matteo would think. “She won’t find out,” Cass promised. “She’ll be gone for days. And I won’t make a very realistic prostitute with a maidservant in tow.” Cass didn’t bother to point out that of all the rules she might break that evening, departing with Falco unchaperoned was the very least of them.
Siena agreed reluctantly, but her good mood had vanished. She led Cass back to the portego, to where Falco waited. A slow smile spread over the boy’s face.
“Almost perfect,” he murmured. He bent down and gave the seam of Cass’s dress a yank. Cass yelped. The shiny fabric slit up the side so that a hint of her shapely calf peeped out. “Now it’s perfect.”
Cass glared at him. Siena gasped, then clapped a hand over her mouth. “Please be careful,” she begged. “Your aunt would never forgive me…”
Falco flashed his dazzling smile at the lady’s maid. “Nothing bad will happen to her. You have my word. "
