The hermit of 69th Street : the working papers of Norbert KoskybyJerzy Kosinski

The Hermit of 69th Street (1988) is Jerzy Kosinski's final novel. The novel was published on heels of multiple accusation of plagiarism and ghost writing.  The book, an "autofiction", portrays a travails of a burnt-out writer named Kosky who author described as Kosinski without the sin. As with it being an autofiction, topics covered are typical Kosinski, such holocaust, Poland (Ruthania), and sex.

The most notable characteristic of the book may that it is filled with footnotes, asides, and quotation. Publishers weekly stated: Almost every page is studded with footnotes and documentation, some consisting of newspaper leads and some culled from imaginary sources. Quotes from a panoply of writers are strewn throughout the text. It is as if Kosinski is obsessed with proving that in the hands of a gifted writer anything can be given meaning and relevance.

In 1991, 3 years after publishing this novel, Kosinski committed a suicide.
