The book was heavily promoted and given an appropriately provocative cover. McGrady’s sister-in-law was enlisted to play the role of the book’s fictitious author, Penelope Ashe, and she did so worryingly well, appearing for interviews in low-cut dresses and singing the praises of sexual liberation and the permissive society.
And the book sold. It sold brilliantly well. McGrady had proved his point rather too well. He soon started feeling guilty about the amount of money he and his confederates were earning. So they exposed the hoax. And the resulting publicity just made the book an even bigger seller.
All of which meant that McGrady had failed. He had been hoping that his experiment would convince American readers to change their ways. They didn't. If anything, their appetite for shite was greater than ever.
It just goes to show that quality and good taste don't always match the public's appetite.
