Gastner/ Posadas County

Gifted 15-year-old Francisco Guzman has become an internationally renowned concert pianist, touring the world under the auspices of his music conservatory. That gives his mother, Posadas County Undersheriff Estelle Reyes-Guzman, plenty of reason to worry - and that's magnified when she learns that he's in Mexico's crime-ridden Mazatlan for a concert series where he may be the target for scam artists and kidnappers.

Posadas County, New Mexico, is in the news. NightZone, a mammoth astronomy theme park, is bringing in jobs, media, and such new infrastructure as a slick narrow-gauge railway to transport tourists from the village of Posadas to the tramway running up the mesa to the project's site. And the Posadas High School girls' volleyball team is on a hot winning streak, exciting everyone. But more news, not good, breaks.

It's 1986. Undersheriff Bill Gastner is enjoying his usual insomnia alone inside his old adobe when jolted by a horrendous noise. Dreading what he will find, he hastens to the nearby interstate exit where a violent crash has occurred. Three teens are dead. The first deputy to join him at the scene is rookie Robert Torrez, the department's newest hire. Before Gastner can head him off, Torrez sees that the dead boy is his spirited younger brother. But were the three dead kids running from someone - or something - rather than speeding?

One blizzardy New Mexico night, Posadas County Deputy Pasquale picks up a toddler scooting his Scamper along the shoulder of State 56. Yes, it's horrifying - a child apparently dumped out of a truck by his father. Nearly as horrifying is what unrolls while Christmas approaches after dad Darrell Fisher's arrest: a request arrives from the US Forest Service to locate a missing range tech and his unit last reported headed for nearby Stinkin' Springs, and the brutal murder of Constance Suarez in the border town of Regál, population 37. 

Posadas County, sitting along New Mexico's southern border, has enjoyed a surge in visitors, jobs, and prosperity since rancher Miles Waddell used much of his inherited half billion to create an internationally renowned astronomy complex atop Torrance Mesa. Passion, not profit, drives Waddell. Yet benefits include a narrow-gauge train linking the village of Posadas to NightZone. But a ripple of unease is felt across the county with the arrival of developer - no, speculator - Kyle Thompson.

Good cops have no use for coincidence. When a driver slams his pickup truck—twice—into a tandem bike being ridden by Carlos Guzman and his fiancée, Tasha, in Briones, California, it's more than a simple hit-and-run; the driver clearly intended to harm them. Undersheriff Estelle Reyes-Guzman gets the call with the news of her son's accident and wastes no time racing to his side. She is greeted by Police Captain Eddie Mitchell, formerly of Posadas County, who allows Estelle to "consult" on the investigation—but only to a point.
