Like all Patterson/Paetro books, this is a very quick read. There isn't as much character development for the members of the Women's Murder Club as in earlier books. This novel has a sub-plot involving the husband of the SFPD detective which I found totally predictable (i.e. not much of a mystery). The main plot could have explored interesting, nuanced reactions some police might have had in response to the villains' motives. None of that was included. Not my favorite book in this series.
