Wolf made no sense to me during the book. I could see the classic "I like you" behavior from him leading up to the kiss he had with Sophie, but it felt awkward and out of place. The only impression I had from him was the scruffy cop that was being difficult. Then when he kissed her, even I had to sit up and ask the book "What was that?"
Despite all of that, the murder and trying to figure out who did it threw me. Too many people involved and the killer surprised me. I thought it might have been Craig because he was so weird.
Anyway, I plan to read the rest of the series.
