I totally disagree with that comment. There are a few common denominators like debunking the myth that mistresses are very rich and living like princesses. But their real life stories are fascinating, very interesting, and can have profound differences, starting with the cities and time periods when they were active, but the most interesting one having to do with their real life experiences.

I think I could write biographies of over 100 pages for two different mistresses, and they would be completely different.

I think the reason we do not read these very interesting stories is that those who have interesting stories to tell are the professional discrete ones, who protect their customers, who to them are much more than customers. This is not a guess. I asked them why they don't write and each one gave the same answer.
