The Flying Saucer Mystery

The Flying Saucer Mystery is the 58th volume in the Nancy Drew Mystery Stories series. It was written in 1980 under the pseudonym Carolyn Keene and published by Simon & Schuster under the Wanderer imprint. It was later republished in both Wanderer and Minstrel imprints, each time with a new cover. In 2005, Grosset & Dunlap reprinted it in the yellow hardback "glossy flashlight" format. The original edition cover and six internal illustrations were by Ruth Sanderson. These illustrations were removed in the two subsequent printings.
