From The Grey House:
Vincent heard the desire in her voice but knew she could be faking it. They were playing each other, using their bodies to try and gain control. Vincent was having fun, but he was also fascinated. This woman was not afraid. She should be, even if she did have Anthony under her control. Either she had no idea what she was doing, and was therefore a child playing adult games, or she knew, and liked it. He found himself hoping she knew what she was doing. He preferred smart, beautiful women. He decided to try one more tactic to win control.
