This book concerns Jane (Eve's adopted daughter) so there's no forensic reconstruction going on. What is going on is actually really involved. Jane is a look alike for a Roman woman/prostitute/slave and there's a search for a treasure that involves this woman. The story is connected to the eruption of Mt Vesuvius but the search has somehow gotten Jane to Scotland. The twist takes us back to the US to stop an attempt to have another homeland security incident. Though a lot of things are resolved at the end of the book there's still a treasure out there waiting to be found. (I'm leaving this review as is and displayed as I don't feel what I have written spoils anyone's enjoyment of reading this thrilling adventure)
