While the story about the psyciatrist who is abusing his patients is the mystery of this book. And it's more about proving that he is the abuser than actually finding him. The story is more about being a writer and the crazies that can accompany it and Sunny's own relationships.
Sunny is engaged to bodyguard a writer, Melanie Joan Hall, whose ex-husband is playing mind games with her. It's interesting to see Sunny describing Melanie putting on the writer role for signings etc., I would have to wonder how much Parker based this on experience and watching other writers.
When Sunny investigates, she does it with the help of another psychriatist who starts to break down some of her barriers. Sunny is also racing against time as there are bodies accumulating.
I found it interesting, it's not quite a crime novel, more a novel with crime in it that's about the people involved. You get to see some of Sunny's background and character and it makes for a deeper character. The crime is so secondary that it really doesn't matter that the resolution seemed a bit rushed.
