The Triple Hoax is the 57th book in the Nancy Drew Mystery Series. It was the first paperback Nancy Drew produced by Simon & Schuster under the Wanderer imprint in 1979, and was ghostwritten by Harriet Stratemeyer. It was later republished again 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 contained six internal illustrations by Ruth Sanderson. These illustrations were removed in the two subsequent printings, but kept in the glossy printing.
