The art of staging

I wonder what prompted Ms. eg. Martin and Sarkozy to pretend to write the "truth"
in his book.
What truth? That she wants to make it public.
She Needs to get on stage as well? Would this for the media to talk about her again.

I am very disappointed that we lent me his book, I certainly did not buy it. Besides, I did not even finish reading. Too many repetitions.
