THINK POSITIVE! HUGS!

While this is the 5th book in this series, it is a new author for me. It work well for me as a standalone, although I would like to know more of the backstory. I will read more by this author when I find the books.
Gabriel Ash is a retired British police security officer who has just recover his son's who he believed were dead. Hazel Best is a rookie police officer who has challenged her superiors in the past.  
An attempted is made to grab his sons as they leave their school. Their nanny is already in the van when Hazel Best breaks up the kidnapping. All involved are safe. The investigation shows the boys were not target but the Nanny was. She was mistaken for school head mistress. It revels a crime that occurred 17 years ago and two surviving persons' life is in danger. Hazel works to correct the wrong done 17 years ago by careless police work. You will be turning the pages fast to find what happen and who was to blame. I highly recommend this book.
