She claims a traitor set her up to declared crazy when she discovered proof of their treason. Beth says she knows they hate her, but she needs their help. In 1947, years after WWII, two women are contacted by a third woman, Beth Finch, who has been institutionalized in the Clockwell Sanitarium. Together, and by calling in a bunch of former BP cryptographers as reinforcements, they get Beth out and decode the messages (the titular Rose Code) needed to identify and arrest the traitor. Years later, Beth calls upon the other women for help to get her out before she's scheduled for a lobotomy. The womens' friendship also splinters at the end due to Beth not warning the others (because they take an oath of secrecy) about a raid that kills Mab's husband and child.

Beth learns there is a traitor at BP, but she gets hauled off to an asylum so that she can't report it.
