Well the letters have gone to Indian public they bought it
There is nothing there to observe it just seems that some writer wanted to sensationalize his book sales to write up a fictional story based on his own , fantasy story
So if two lawyers are fighting for same cause in South Africa write letters to update each other how their lives are unfolding etc that makes it extra ordinary
So if someone tells about their personal lives with their wife its extra ordinary not really people talk about their marrige issues with friends over drink all the time
These days due to Facebook we all are intouch with friends world wide , and we click on the like button in facebook on friend's comment so who is to tell after 400 years some idiot will write a book and said because you clicked on the like button on facebook on friend''s comments that showed you were in some sorta of fanty love relation lol
I mean really ... the letters are just a modern day age facebook of that time
