There isn't much crime in Stoneleigh, Massachusetts, a college town, a mountain getaway for the quietly rich. So when Edward Inman, owner of Stoneleigh Sentinel security, gets a late-night alarm from the home of one of his wealthiest clients, Doyle Cutler, he does a routine check and thinks nothing more of it-until a local student claims that she was sexually assaulted that night at Cutler's house.

Edward soon finds himself drawn into the girl's story, and his investigation leads him to his old girlfriend, whose teenage son may know the truth about what happened that night. Security is a timely, wry, and riveting story of adults and children, secret lives and civic culture, suspicion and sexual hysteria.
