In the 1970s, Rian makes a choice outside the norm. Not only is she a woman with a husband and children, but she also becomes one of the first female police officers. In her quest for excitement and fulfillment, she climbs a mountain one step at a time through a mire of prejudice, egos, and archaic attitudes.

Great Mystery is inspired by the author's own life experiences and tells the story of Rian McCarren Clark, a woman police officer who battles for the innocents. She fights for the victims of a judicial system that often re-victimized them and left families in tatters.

This portrays the life of a hero who broke the barriers of a man's world in law enforcement. As she gets older, she is left with memories of victims of violence, greed, decadence, and perversion. She also finds love, loss, and the fulfillment of family, all while caring for the abused and neglected.
