This was a great murder mystery and so far, my favorite in the Michael Bennett series. I like when the author lets the reader know who the killer is and gives insight into his life and routine, such is the case in this book. The story surrounds the kidnapping of children of wealthy parents and held for ransom. The killer objects to the wealth of the families and wants vengeance for those in third world countries where clean water is a daily fight. I also like the family dynamic of the Bennett family, that include Michael, the NYPD detective, his 10 children and his pastor father, Seamus. Looking forward to the next one,
