This is book 22 of the Right Thing Series. The series is a continuing story of former sheriff Sue Davis Lang. In this book Sue learns of a woman's body found floating in the Gulf of Mexico. Out of curiosity she looks further into the story and finds there is a possibility that a serial killer may be responsible.
Sue has taken a stranger under her wing and now there are two vigilantes. It did add to the story to have a computer geek on board. I'd like to see some progression with David and Morgan. I think those characters are underused.
