The Bletchley Circle Re-Airs Tonight At 9 On PBS.
Catch up if you haven't already. Loved this and the second season begins April 13th at 10 on PBS.
"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."- PBS
