This is a taut and exciting mystery thriller that kept me guessing almost up until the end who the killer was and how they managed to commit their crimes. It was just good enough that I now want to read further books in the series. It has an intriguing protagonist and some great supporting characters. I will definitely be checking out more books in this series. If you're looking for a thrilling detective novel that will keep you on the edge of your seat, this is the book for you.
