From Protector of the Grey House:
Vincent drummed his fingers on his desk and narrowed his eyes at the look on his friend’s face. “It’s obvious you enjoyed yourself with Natalia last night. Don’t let it happen again while she’s mine.”
“You enjoy Mierka when you will.” Joseph’s voice was pleasant, with just a tinge of irony.
Vincent’s fingers drummed quicker, annoyed at the truth in Joseph’s simple words, and at his own jealousy. His thoughts stopped as he understood he had made a decision regarding Natalia. He looked away from Joseph, toward the door, then looked back. He stood.
