Reflective surfaces abound in Daughter of Mine. Mirrors generally symbolize validation in the sense of seeing one’s own reflection. In the novel, they speak to The Importance of Uncovering Concealed Truth. The lake that features so prominently in the novel is named Mirror Lake. However, though the central feature of their town is a mirror, the people of the community refuse to reflect on what is really happening. When lengthy drought afflicting the entire country lowers the water level, objects that lie beneath the surface are exposed. Typically, visitors to the lake are far less interested in examining the lake’s bottom than in skimming its waves on jet skis or speed boats. This attitude is analogous to the residents’ snap judgments about people in the community. Someone’s looks and actions are judged to be proof of their moral character, and qualities below the surface go unaccounted for. The diner, Reflection Point, literally becomes a turning point and a place to reflect on the evidence coming to light.

The mirrors in Perry’s office function similarly to the lake. Initially, Hazel assumes that her father set up the mirrors as a means to surveil the backyard while seated at his desk. Since he is a detective, he is always observing the behavior of others to determine if they’ve committed a crime.
