A puzzling new case has just hit Sheriff Joanna Brady’s department, demanding every resource she has at her disposal—as well as help from neighboring law enforcement agencies and the Feds. The bodies of two women have been found at the base of a nearby peak, known to Bisbee locals as Geronimo. Is this a terrible accident, a case of murder/suicide, or a double homicide? The investigation takes a puzzling twist when Joanna discovers that one victim was a local teacher and minister’s wife, while the other was a brilliant microbiologist working toward her Ph.D.—two vastly different women with seemingly no connections to link them. As Joanna and her team methodically hunt down answers, they begin to uncover a knotty web of sordid secrets and evil lies—clues that take the valiant sheriff down a winding and dangerous road that leads shockingly close to home . . . and close to a desperate and determined killer.
