Good, good, good. Love the Britishness, the wry humor, and Peter has grown on me as a protagonist. Each book stands alone, but over the course of the series we are learning more and more about the characters' backgrounds and the overarching plot of a hidden antagonist is coming to a boil. Audio book narrator is superb.

Cautions: Listened to the audio book, so the number of F words really stood out. "Adult" themes as well.
