At the peak of Bletchley's success, a total of twelve thousand people worked there of whom more than eight thousand were women. . In The Debs of Bletchley Park and Other Stories author Michael Smith, trustee of Bletchley Park and chair of the Trust's Historical Advisory Committee, tells their tale. Through interviews with the women themselves and unique access to the Bletchley Park archives, Smith reveals how they came to be there, the lives they gave up to do 'their bit' for the war effort, and the part they played in the vital work of 'Station X'.
