Bletchley Park was where one of the war's most famous and crucial achievements was made: the cracking of Germany's ';Enigma' code in which its most important military communications were couched.This country house in the Buckinghamshire countryside was home to Britain's most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa.But, though plenty has been written about the boffins, and the codebreaking, fictional and non-fiction from Robert Harris and Ian McEwan to Andrew Hodges' biography of Turing what of the thousands of men and women who lived and worked there during the war? What was life like for them an odd, secret territory between the civilian and the military?Sinclair McKay's book is the first history for the general reader of life at Bletchley Park, and an amazing compendium of memories from people now in their eighties of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in) of a youthful Roy Jenkins, useless at codebreaking, of the high jinks at nearby accommodation hostels and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other's work.Pre-order the new book, Secret Listeners, by Sinclair McKay. Published on October 4, 2012.Before Bletchley Park could break the German war machine's code, its daily military communications had to be monitored and recording by ';the Listening Service' - the wartime department whose bases moved with every theatre of war: Cairo, Malta, Gibraltar, Iraq, Cyprus, as well as having listening stations along the eastern coast of Britain to intercept radio traffic in the European theatre. This is the story of the - usually very young - men and women sent out to farflung outposts to listen in for Bletchley Park, an oral history of exotic locations and ordinary lives turned upside down by a sudden remote posting - the heady nightlife in Cairo, filing cabinets full of snakes in North Africa, and flights out to Delhi by luxurious flying boat.
