Gifted fifteen-year-old Francisco Guzman has become a renowned concert pianist, touring the world. 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 kidnapped. Estelle's worries go from bad to worse when her uncle surfaces and leaves a trail of corpses in his wake. Estelle's attempts to glean family history-the story of her childhood-from her adopted mother, a woman now in her nineties, go nowhere. Meanwhile, escalating events put Sheriff Bobby Torrez in jeopardy, as they do newly wealthy rancher Miles Waddell and his pet project, the multi-million dollar theme park, NightZone. Just when his sage advice might be most useful, former sheriff and family friend Bill Gastner takes a dive-in the shadows of his own garage. Now his far-flung family is added to the mix of people and events astir in the boot heel of New Mexico. Blood Sweep marks the author's 20th title in the Posadas County Mystery Series, set in the sunny and sometimes blood-soaked south-western corner of New Mexico. Havill is also the author of four traditional westerns, and the historical/medical adventure series featuring Dr. Thomas Parks.
