I have really enjoyed every one of this series - have just binged read them in order and found that kept the theme rolling along nicely. Each book could be read on its own without the series but think the continuity is better. Each book though has a different event/murder which shows the author has talent to pull the reader into each story but each book's background blends together. Feel they are very well researched. This is an excellent author and I will continue to read each and every book he writes. Highly recommended. To the author, thank you.
