In her young years after leaving her job as a buyer for a department store, she ended up taking a receptionist job at a call girl service. She answered phones, dispatched the girls, and generally got an idea of how the business words. Eventually she got frustrated with how unfair the service was to the girls that worked so hard for it. So she quit, and started her own service. She basically fixed everything that was wrong with call girl companies and came up with a marketing plan and company policies that were fair to the women and created an enjoyable work environment for the girls that worked for her. She hired intelligent women such as medical students and college students. And all clients were required to actually have conversations with the women and spend time with the first. No one was ever just sent over to have immediate sex. And girls were not required to work several clients in one night. And they were even allowed to leave if they didn't like the client, and still got paid a small amount for showing up and at least trying.
The book goes into such interesting detail that you get to know the profession and the clients intimately. Sadly, it also covers every detail of how she got caught and the business was eventually shut down. I loved the book. It's out of print but you can buy it used. Or if anyone wants to read it, you can have my copy. Just come and get it before I move so I don't have to pack it.
