Behind the Enigma: The Authorised History of GCHQ, Britain's Secret Cyber-Intelligence Agency

This is a very densely written book - full of acronyms and hopefully, informed detail. Blows some holes in the Enigma mythology - but puts it firmly in the place where it should always have been. However, it also goes into social details as regards numbers of women employed, their social backgrounds, their employment and also their gradual rise in the ranks as societal pressures and backgrounds changed. It is complex - I'm doing about 40 pages a day - and this is a long book - but it is very detailed and takes careful reading to ensure that you fully understand what is happening. Well worth the reading, perhaps it could have been shortened a little - but lets face it - the author is dealing with a difficult and very detailed history. His account of Stuart Hampshire - a philosopy don, being brought in to sort out the management was astonishing to me - and more importantly his obvious competence in dealing with difficult problems in management and structure. Oh, if he were in charge of the Covid Crisis I wonder how much better off we would be now. Anyway- this is a dense but ultimately rewarding book that pulls no punches - but also allows for brilliance to have a light shone where necessary.

Good condition, got what I paid for

Vient couronner une longue série d'ouvrages sur le sujet (Enigma, GCHQ, renseignement et cryptopgraphie) Mais ne se limite plus à la seule Seconde guerre mondiale et couvre une période beaucoup plus récente, après être remonté aux origines, dès le début du XXe siècle ! Ouvrage majeur sur le sujet...

A true must read for those that follow the crypto world. Well researched. Well written. Furst person accounts. Impeccable interpretations.
