Feisty middle-aged piano teacher Sally Freberg stumbles on a murder-in-progress after a Kansas City concert. Why would anyone conspire to kill mild-mannered archeologist Henry Decker? His brutal knife-slaying stymies all, especially the police. What's the motive? Apparently none in the victim's estranged Santa Fe family stands to gain. But----what's this about Decker's pre-concert mention of an opera? How might Sally follow THAT slender lead to uncover a motive and unmask the conspirators? To nail it all, Sally teams with an ambitious KCPD detective for a deadly pursuit near Decker's digs among ancient pueblo ruins. It's a wild chase during a fierce New Mexico monsoon, imperiling Sally----and altering her life.
