THE BLETCHLEY CIRCLE follows four ordinary women with the extraordinary ability to break codes, a skill honed during World War II when they worked undercover at Bletchley Park, site of the United Kingdom’s main decryption establishment. Now in 1952, Susan, Millie, Lucy and Jean have returned to civilian life, keeping their intelligence work secret from all, including family and friends.
