This beautifully presented slipcased collector's edition of the best selling title, The Lost World of Bletchley Park is a comprehensive illustrated history of this remarkable place, from its prewar heyday as a country estate, its wartime requisition and how it became the place where modern computing was invented and the German Enigma code was cracked, to its post-war dereliction and then rescue towards the end of the twentieth century as a museum.

Removable memorabilia includes:

1938 recruiting memo with a big tick against Turing's name

Churchill's 'Action this day' letter giving code breakers extra resources

Handwritten Turing memos

Top Secret Engima decryptions, about the sinking of the Bismark, German High Command's assessment of D-Day threat and the message announcing Hitler's suicide

A wealth of everyday items such as authentic theatre posters, a map of Bletchley Park, canteen menus, teleprinter print-outs of codes, the Colossus paper tape spooled through machines

Newly redesigned interiors with 25% new content, high end slipcase package featuring removable facsimile documents, this is an essential purchase for everyone interested and wanting to experience the place where code-breaking helped to win the war.
