I'm really enjoying this series. This second book had a great main plot, although it's hard to get used to the 'bad guy' not being brought forth and made to face justice. The investigative team finds out the facts about what happened during a crime, but takes no part in bringing the perpetrators of the crime to justice. It doesn't detract from my enjoyment of the story, but it's different. Feels a bit unfinished.
I found the secondary plot to be neglected; there was a resolution to it without there being much storyline in front of it: you saw the characters plotting it, and you saw the protagonists ending it, but almost nothing in between. Made that feel very disjointed. Great main characters, each interesting, amusing and compelling in their own right.
