This book grabbed me from the start and didn't loosen its grip until about a third of the way through. It was riveting! I felt like I was on Boylston at the time of the explosion. After that, it is a very well-researched and reported story full of questions for which we may never get any answers. I've always had a high regard for the FBI and I don't tend to like the idea of a conspiracy when it comes to terrorist attacks but I have to say this book has me questioning my beliefs. The FBI certainly seem to have many things to answer for here. I had no idea the case was this complex. A very interesting read!!
