How was Bletchley Park made as an organization? How was signals intelligence constructed as a field? What was Bletchley Park's culture and how was its work co-ordinated? Bletchley Park was not just the home of geniuses such as Alan Turing, it was also the workplace of thousands of other people, mostly women, and their organization was a key component in the cracking of Enigma. Challenging many popular perceptions, this book examines the hitherto unexamined complexities of how 10,000 people were brought together in complete secrecy during World War II to work on ciphers. Unlike most organizational studies, this book decodes, rather than encodes, the processes of organization and examines the structures, cultures and the work itself of Bletchley Park using archive and oral history sources. Organization theorists, intelligence historians and general readers alike will find in this book a challenge to their preconceptions of both Bletchley Park and organizational analysis.

'Christopher Grey has written a very innovative and captivating book about 'decoding' organizations, which can also be used to decode organization studies … Grey did a great job in promoting a new understanding of organizational phenomena, in a double sense: by decoding the organization at Bletchley Park, he also contributed to the development of the historical ethnography of organizations. Despite its empirical and theoretical relevance, secrecy is still a neglected topic in organization studies, and Grey's work is a rare exception. Highly recommended.'
