Book #4 in the Nancy Drew Mysteries series.

A quiet summer getaway turns into a high-stakes case of impersonation, sabotage, and stolen treasures in this thrilling adventure starring the world's most beloved girl detective, Nancy Drew. When a string of bizarre incidents disrupts preparations at the elegant Lilac Inn—cryptic warnings, disappearing heirlooms, mysterious lights beneath the water, and a stranger posing as Nancy herself—the search for answers becomes a race against time. As danger closes in, Nancy confronts sinister plots, double identities, underwater peril, and carefully planted clues that reveal a conspiracy far larger than anyone suspects. With her trademark courage, intelligence, intuition, and deductive skill, she pieces the mystery together from silent footprints, coded messages, and suspicious guests who know more than they admit.

Perfect for readers who love girl detective adventures, Golden Age children's mysteries, and gothic suspense, The Mystery at Lilac Inn remains one of Carolyn Keene's most beloved early Nancy Drew mysteries. A cornerstone of twentieth-century juvenile mystery fiction, this timeless classic is ideal for collectors, libraries, classrooms, homeschool reading lists, young readers, and anyone who enjoys vintage crime fiction, amateur sleuths, clever puzzle-solving, and unforgettable heroines.

If you enjoy this Nancy Drew mystery, make sure you don't skip reading Books #1 through #3 of the series, beginning with The Secret of the Old Clock, then The Hidden Staircase, and finally The Bungalow Mystery.
