Daddy's Girl by Lisa Scottoline

Nat Greco, a law professor at UPenn, has always felt overshadowed by her family. When a colleague asks her to accompany him to a local prison to do a lecture, she agrees. While there, a riot occurs and a prison guard is killed, but not before telling Nat to tell his wife "...it's under the floor." Nat feels the right thing is to tell Barb Saunders her husband's last words. This information plunges Nat into danger and a race to find the truth and save her reputation. In this book, Scottoline again departs from her series characters at Rosato and Associates. The book, though, is every bit as good as her others. I hated to put it down.
