The house next door explodes in a gasoline-fueled blaze, sending psychologist Estela Nogales and an eclectic collection of neighbors racing to fight the flames. Once the fire is quelled, residents of the village of Arroyo Loco must conduct their own investigation to find the arsonist living among them. What begins as speculation over coffee becomes a more urgent and dangerous search when a body is discovered, another neighbor turns up missing, and a shocking secret is revealed. Too often joined by Estela’s irrepressible border collies, residents must negotiate the rules of a dysfunctional homeowners’ association (aren’t they all?) as they try to solve the mysteries before anyone else falls victim.
