Exit wounds : a Joanna Brady mystery, book 11

Summary: The heat is a killer in Cochise County, Arizona, with temperatures over 100 degrees. In the suffocating stillness of an airless trailer, a woman is lying dead, a bullet hole in her chest. Why someone would murder a harmless loner with a soft spot for stray dogs is only one of the questions nagging at the local police; another is why the killer used an eighty-five-year-old bullet, fired from the same weapon that slaughtered two other women who were discovered bound, naked, and gruesomely posed on the remote edge of a rancher's land. The slayings are as oppressive as the blistering heat for Sheriff Joanna Brady, who must shoulder the added double burden of a brutal reelection campaign and major developments on the home front. With suddenly more on her plate than many big-city law officers have to contend with, Joanna must put marital distractions and an opponent's dirty tricks in the background and deal with the terrifying reality that now threatens everyone in her jurisdiction: a serial killer in their midst.
