: The book became infamous for its portrayal of a character widely believed to be based on Polish actress Weronika Rosati
WorldCat shows that fewer than 20 libraries globally hold a copy of Nocnik . Harvard's Widener Library has one. Bibliothèque Nationale de France has one. If you are a university student, request an ILL. You will receive a physical scan (not a searchable PDF, but a series of jpegs). That is the closest you will get to the "pdf" you seek.

Shortly after its release, actress Weronika Rosati filed a lawsuit against Żuławski and his publisher, alleging that the character "Esterka" was a thinly veiled and defamatory representation of her.
