New York: B. B. Sales, Inc. 1967. Paperback. 148p., ads, illustrated with b&w stillsfrom softcore movie, very good first edition PBO in original camp pictorial wraps. Erotic pulp fiction. Olympic Foto-Reader F104.
Movie tie-in. The book says story by John Nichols but IMDB says Jean Van Hearn. The movie site also says "A gang of four lesbian inmates escapes from prison and kidnaps the boyfriend of a wealthy woman. She hires a tough private eye to find her boyfriend and rescue him." but this reader doesn't find much lesbianism.
