It is barely a crime -- just the theft of a single pack of gum. But each crime that follows is bigger, and each accompanying note promises the next crime will be even worse. When FBI Special Agent Dagny Gray is asked to investigate the gum thief's fifth crime, a bank robbery, it seems like an intriguing case. However there is nothing funny about the double murder that follows. Special Agent Gray becomes part of an unlikely trio of three investigators competing to stop the escalation of crimes, often with unconventional tactics. Bent on justice, hobbled by the Bureau, and burdened by personal demons, Dagny Gray races to untangle the meaning behind the gum thief's madness. Can she catch him before he reaches the cataclysmic finale of his escalating spree?
