When Mosey Frye, real estate agent and amateur sleuth, hunts for a summer house on the grounds of an abandoned plantation, she finds not only the house but also skeletal remains at the bottom of an old cistern. That same day, news of the horrific stabbing death of an eremitic nun leaves the citizens of Hembree in hang-jawed shock. Given that the tumble-down estate belonged to the dead nun's family, Mosey insists there must be a connection between the two events. But Police Chief Gus Olivera, predisposed against Mosey and the Church, scrambles to find a suspect among members of the clergy. Will Olivera solve one on his own? Or will his hopes be dashed when Mosey, once again, drops the clue that points to the killer?
