#4 in the series. I just love these books. I can just see these guys running around East Tennessee solving murders. This one is centered in Oak Ridge and yes, involves OR's nuclear past. A modern day murder (or two) along with a 1940's murder set the stage for this mystery. I think being one of Dr. Brockton's friends is dangerous, but being a romantic interest is just deadly! I like the history lesson on the work done at OR and the personal twists the writers always add. A very entertaining read.
