This book is quite good, in a way it is possible, psychologically speaking, since Dianas personality was vulnerable to fall in love with someone like Ahmed Ben Hassan. Diana Mayo had a lack of love all her life, and suddenly she falls in love with her kidnapper. This happens quite frequently and its called the sindrom of Estocolm. There are somethings that I didnt like of this novel. First, the way in which Diana Mayo realizes, so suddenly, that she is in love and the severe change in her; and also to consequent that kind of relationships, which only mentally illed people would have. Any way the book is very romantic and it is one of my favorites, even though is a little bit corny.
When this was published (1919) a review referred to "scenes of incandescent passion" -- after all these years, I agree. You don't have to be graphic to be senseous.
