Cameron Winter was born with a "strange habit of mind"--the ability to recreate detailed crime scenes in his imagination and dissect the motives and encounters that produced them. And after reading a puzzling news story about a wealthy family killed in a small town in the Chicago suburbs, he can't resist the chance to apply this deductive power in the pursuit of justice for the victims. Three members of the family, along with their live-in nanny, were pulled from their burning mansion, already dead from gunshot wounds. The only survivor is a young boy whose memory of the event raises more questions than answers. The police seem happy to settle on a simple explanation and arrest the most obvious suspect--but Winter knows that obvious solutions are seldom the correct ones. While Winter's investigation is welcomed by many, the lead detective makes it clear he not only wants Winters to stop looking for answers, but to stay out of his town altogether. Winter begins to understand why as he slowly uncovers crimes and unsavory behavior that had been ignored long before the killings, and in the process grows increasingly determined to find the real killer and expose the rot beneath the town's sanitized fa?ade. And as the inquiry brings all-too-familiar sins to the surface, he'll have to confront his own inner demons once and for all.
