"New York Times" bestselling author Lisa Scottoline delivers a fast-paced thriller in which a young law professor must unravel a dangerous conspiracy to see justice done. Law professor Natalie Greco has an ordered life. She feels a passion for teaching, especially her arcane seminar on the History of Justice, even though the course is pathetically undersubscribed in the high-powered law school. She has an attentive boyfriend and a protective family, although her testosterone-fueled big brothers and very successful parents tend to overlook the quiet Nat. Then one terrible day, everything changes. Nat accompanies her colleague Angus to a prison in Chester County where he's a guest lecturer. It's a nice day for a drive through the countryside, the site for much Underground Railroad activity during the Civil War.
