Happy heavenly birthday to the great Burt Lancaster!
Honestly, Hack just wanted to write a book titled “Murder at the Nudist Colony” and when he found out Lancaster’s birthday coincided with its release date, he just had the cover artist redo the cover with the actor in his Elmer Gantry role as the victim. The story is more about Jonny the detective running around the nudie colony seducing the women who stay there.
