" You are not my husband yet,” she said softly, but with force. “And I do not have to listen to you.”
Luca’s fork fell to the table with a clatter. “Then you are a sillier girl than I thought,” he burst out. “And I would urge you to be more careful. Where have you been spending your time, Cassandra?”
“One might ask the same question of you,” she said. Both Siena and Madalena had claimed to have seen him on the Rialto. They couldn’t both be mistaken. Her eyes narrowed. “How long have you really been in Venice, Luca? You told me you had just arrived, but you were seen in the city more than a week ago! How do you explain that?”
“All I have done since arriving in Venice is attend to your safety.” Luca flung his balled-up napkin onto his untouched dessert plate. “What you don’t know can hurt you, Cass.” He pushed his chair back abruptly from the table.
For a second, no one said a word. The outburst had startled even Agnese into silence. Cass was sure that the servants were taking in every word.
Luca seemed suddenly to remember that there were others in the room. He passed a hand through his hair. “I apologize,” he said stiffly. “I don’t know why I got so upset.” He brushed a few crumbs from his clothing as he stood. “If you will both excuse me, I have some reading I must complete.”
Cass turned to her aunt the second Luca disappeared into the portego. “What on earth do you suppose that was about?” she asked.
“It appears that during his time in France, your fiancé developed a bit of a temper,” Agnese said mildly, as though Luca’s outburst were perfectly normal. She blotted her mouth with her napkin and signaled a servant to bring her a second pastry. “Let’s just hope he saves some of that passion for your wedding night. "
