With the safety of San Francisco's entire school system as stake, Lindsay Boxer has never been under more pressure. To solve the School Night case, Lindsay turns to her best friend, investigative journalist Cindy Thomas, as the chief of police and the press clamor for an arrest. Together, Lindsay and Cindy take new approaches, and unexpected facts about the victims leave them stunned."-- Provided by publisher.
