Adventures of the Green-Eyed Lady

Frankie Leigh finds herself taking on her strangest cases ever, a case for Maude Roper. Roper is being blackmailed by Olivia Goad; a dominatrix Maude has gotten messed up with. Olivia is better known as the Green-Eyed Lady. Olivia wants a million dollars from Maude, or she is going to publish some pretty embarrassing letters that Maude wrote to the dominant Olivia. Maude has tried and failed to recover the letters using another PI, so she tells Frankie she needs Frankie's skills and her gender.
Maude thinks the previous PI failed because he was a man and Olivia was just too clever and scared him off. Maude tells Frankie that the letters are with Olivia somewhere at a camp ground in southern Indiana. The catch is, the camp ground is also a nudist retreat. That means Frankie will have to go hunting for Olivia and the incriminating letters completely naked. Frankie rents a top line camper and heads for Indiana and Bright Estates nudist camp.
