Marie Antoinette and the French Revolutionary Era

Before the Revolution Marie Antoinette was already aware of things going on and throughout she wants its stability. So is it fair to say that she became much more politically aware in these later years perhaps out of necessity? I think that's absolutely true. She entrusts letters to designated bearers so she will get someone who she trusts to take a letter It won't be sent through normal sort of postal circuits but she also uses a lot of codes she gets good at cryptography. One of the means there is doing that is something I think a lot of us are played with when we were young and that is writing in things like lemon juice you know you put the piece of paper near a flame
