I really love things like Criminal Minds and murder related shows so it was really interesting to read about the true person behind real cases such as those that are shown in the show. It was written very well with a lot of suspense and covered a variety of very high profile cases that the author solved in his life such as the Golden State killer among others. I really enjoyed this book and I think that anyone with similar interests in things such as murder mysteries or who enjoy shows such as Criminal Minds and want to learn more about the true stories of the killers and the people who catch these criminals will also enjoy this book quite a bit. The cover is also pretty cool as you can see I think though it may not be the prettiest book it definitely fits the theme of the story with the suspenseful atmosphere and the riveting storyline that it follows.
