" We should tell her,” Cass whispered, once Siena had disappeared.
“What reason do we have to tell anyone? I’m still wishing you hadn’t told me.”
“She might be able to help,” Cass said in a low voice. “When it comes to the goings-on of Venice, the servants know almost as much as the Senate. Maybe more.” She craned her neck to peer through the doorway. The dark had seemingly swallowed Siena whole. “And, if we don’t tell her, she’s going to think you and I are…”
Falco smirked. “We couldn’t have that now, could we? Lord knows I don’t want to give the woman reason to attack me again.” He touched the crown of his head gingerly and winced. “But what makes you think we can trust her?”
Cass had to look away when Falco took God’s name in vain. How could he do that so casually? Her fingers went to her waist, but she’d already removed her rosary for the night. She’d say a prayer for him later, she decided. “She covered for me last night. She didn’t tell Agnese I’d snuck out.”
A smile played at Falco’s lips. He brushed an unruly lock of Cass’s hair back from the left side of her face. “How did you manage to get caught in the first place?” he asked.
“Long story.” Cass still hadn’t found his nude drawing, and she didn’t want to confess to having lost it. She hoped it would turn up before Agnese got back. If the old woman found it, she might keel over on the spot. "
