Good Enigma Book Recommendations?
 

Having just finished Clay Blair's "Hitler's U-Boat War: The Hunted", I have a hankering for some good books about the breaking of the Enigma code.

With a cursory search of Amazon, I found three that looks promising:

"The Ultra Secret" by F.W. Winterbotham
I figure I should start with the original but it sounds like alot has been declassified since this was first published in 1975.

"Codebreakers: THe Inside Story of Bletchley Park" by Sir F. H. Hinsley

"Enigma: The Battle for the Code" by Hugh Sebag-Montefiore

Any other suggestions or reviews of the above would be appreciated.
