Describe the trials of trying to obtain the French naval ciphers.

CYNTHIA tried to obtain the French naval ciphers. She openly asks Brousse for them, and he tells her who has access. They work it out so the guard is drugged and a team from BSC walks in and determines the combination to the safe where the codes are stored. It was daylight so they left without the codes. On the next several visits, CYNTHIA tried to open the safe. Finally, they bring the BSC man in again and accomplish their goal.
