November is usually quiet in Holcomb, Kansas, but in 1959, the town is shattered by the quadruple murder of the Clutter family. Suspicion falls on Nancy Clutter's boyfriend, Bobby Rupp, the last one to see them alive.

New Yorker Carly Fleming, new to the small Midwestern town, is an outsider. She tutored Nancy, and (in private, at least) they were close. Carly and Bobby were the only ones who saw that Nancy was always performing, and that she was cracking under the pressure of being Holcomb's golden girl. This secret connected Carly and Bobby. Now that Bobby is an outsider, too, they're bound closer than ever.

Determined to clear Bobby's name, Carly dives into the murder investigation and ends up in trouble with the local authorities. But that's nothing compared to the wrath she faces from Holcomb once the real perpetrators are caught. When her father is appointed to defend the killers of the Clutter family, the entire town labels the Flemings as traitors. Now Carly must fight for what she knows is right.
