I felt this was another strong addition to the series. I was more than a little annoyed to see Newberry's smoking Opium again. It's for a good reason, I suppose, but what was the point of cleaning him up in the last book if he's immediately going to become addicted again?
I liked the antagonist. I would have liked to see more of her, actually. I though the sections from her point of view were interesting.
I'd also like to have a case that doesn't involve the queen or a plot against the queen just for a change of pace
