This was not enjoyable as an audio book - I didn’t realize how much I must usually skim when reading Jesse Stone books - so much “Jesse said”- “She said” - “Suit said” in the dialog - it annoyed me. 
The story line of “who killed the teenager whose body was found in the water” was diluted by the side theme of “Jesse loves Jenn and drinks too much” - and “man abuses wife because he wants to control her and now he’s going to kill her”.
The search for the killer was not engaging for me - and now that I've finished the book -

I think they played down the issue with the dead girl to focus on the teen age prostitution ring. Was someone finally charged with the murder? And what happened to the controlling mother in the dead girl's family?
