Victim of machination, Captain Alfred Dreyfus was sentenced in December 1894 to deportation for high treason. His wife Lucie made a pact with him: to live, whatever the cost, while awaiting rehabilitation. For five years, the Dreyfus couple exchanged hundreds of letters. These letters were analyzed, censored, copied, and confiscated, because the administration was convinced that they concealed a secret code between the couple. For Alfred, they became a weapon of survival. They are at the heart of one of the great contemporary events, the advent of human rights.
