5.0 out of 5 stars
Best book on Bletchley park, 11 Jan. 2014
excellent book which explains the position, and importance of the tunny work undertaken by the code breakers and how the machines where developed.
It is gives credit to Alan Turning Tommy Flowers and Bill Tutte for the extraordinary achievements in code breaking and the design and manufacture of the first computers.
A master piece
