Mystery at Lilac Inn: A Positronic Book

A quiet summer getaway turns into a high-stakes case of identity theft, sabotage, and stolen treasures in this fourth adventure featuring the world's most beloved girl detective. When a string of bizarre incidents disrupts preparations at the elegant Lilac Inn-cryptic warnings, vanishing heirlooms, mysterious lights beneath the water, and a stranger impersonating Nancy herself-the search for answers becomes a race against time.

As danger closes in, she confronts sinister plots, double identities, underwater peril, and carefully planted clues that point to a crime far bigger than anyone imagined. With her trademark mix of bravery, intelligence, intuition, and deductive skill, she pieces the mystery together from silent footprints, coded notes, and suspicious guests who know more than they admit.

Perfect for fans of classic detective fiction, girl-detective adventures, gothic suspense, and Golden Age mysteries, The Mystery at Lilac Inn delivers everything readers love about the series-clue-by-clue investigation, atmospheric settings, emotional stakes, and a heroine who refuses to back down.

A cornerstone of 20th-century mystery literature, newly available in the public domain and ideal for collectors, libraries, classroom libraries, homeschool reading, YA mystery fans, and lovers of vintage whodunits and suspenseful puzzle-solving.
