There wasn't anything more to be done. Nick had arranged for two deputies to stay at the station and, though off duty, Steve would be at the Christmas party with him just in case. He couldn't justify scheduling more men on Christmas Eve. They all had families and plans. Nick hadn't bothered to relay his fears to anyone else but Lafferty. The extra attention might make the guy change his mind in making a move tonight. If he would at all.
This guy, whoever the hell he was, went against everything Nick had learned about perps in police training. He killed, but didn't seem to take pleasure in it. He had ample opportunity to go after others, but hadn't. He had more than enough chances to silence Trish for good, yet had made no real attempt. Instead, he'd called with threats and left notes. The thing was so damn bizarre Nick almost laughed.
