Naked Came the Stranger is a 1969 novel written as a literary hoax poking fun at the American literary culture of its time. Though credited to "Penelope Ashe", it was in fact written by a group of twenty-four journalists led by Newsday columnist Mike McGrady.
McGrady's intention was to write a book that was both deliberately terrible and contained a lot of descriptions of sex, to illustrate the point that popular American literary culture had become mindlessly vulgar. The book fulfilled the authors' expectations and became a bestseller in 1969; they revealed the hoax later that year, further spurring the book's popularity.
Mike McGrady was convinced that popular American literary culture had become so base—with the best-seller lists dominated by the likes of Harold Robbins and Jacqueline Susann—that any book could succeed if enough sex was thrown in. To test his theory, in 1966 McGrady recruited a team of Newsday colleagues (according to Andreas Schroder, nineteen men and five women) to collaborate on a sexually explicit novel with no literary or social value whatsoever. McGrady co-edited the project with his Newsday colleague Harvey Aronson, and among the other collaborators were well-known writers including 1965 Pulitzer Prize winner Gene Goltz, 1970 Pulitzer Prize winner Robert W. Greene, and journalist Marilyn Berger.
The group wrote the book as a deliberately inconsistent hodge-podge, with each chapter written by a different author. Some of the chapters had to be heavily edited, because they were originally too well written. The book was submitted for publication under the pseudonym "Penelope Ashe." (She was portrayed by Billie Young, McGrady's own sister-in-law, for photographs and meetings with publishers.)
The publisher, Lyle Stuart, was an independent publisher then known for controversial books, many with sexual content. According to Stuart, he had appropriated the cover photo (a kneeling nude woman with very long hair down her back, photographed from behind) from a Hungarian nudist magazine; the model and photographer later demanded and received payment.
