Story Synopsis
Nancy Drew is invited to Mirror Bay in the Cooper Mountains to investigate mysterious sightings of a "spectral" green light and a glowing figure that glides across the water. The mystery takes a personal turn when Nancy’s friend, Aunt Eloise, becomes involved in a legal dispute over the bay's property.
Nancy, Bess, and George uncover a smuggling operation hidden in the mountain's caves. Navigating dense fogs and treacherous cliffs, Nancy must prove that the "ghost" is a high-tech ruse and unmask the criminals before they escape. It is a masterful blend of atmospheric suspense and 1970s detective work.
This 1972 printing is a classic of the Yellow Spine Era, featuring high-gloss picture boards. This specific variant is identified by its **Yellow Number** on the cover and **white endpapers**. Reference: series-books.com.
