The case of Manuel Rodriguez is a prime example. Rodriguez is accused of brutally murdering a college student, a kind young man who had a bright future. Marty has worked hard on this case; as the mother of a teenage son, she identifies with the murdered boy's grieving parents. Her case against Rodriguez is so solid that even public defender Harry Madigan -- the champion of the Cape's underdogs -- expects a conviction. And, on Memorial Day, exactly a year after the crime, the verdict comes in: guilty as charged. Justice prevails. Then, with Rodriguez behind bars, another body turns up in disturbingly similar circumstances. Did Marty and her colleagues target the wrong man? Her supervisor -- Geraldine Schilling, who aspires to be the county's first female D.A. -- refuses to reopen such a high-profile case. Why should she? The prosecutors played by the rules and won big. But Marty fears that the real killer will strike again.
