The Secret Lives of Codebreakers: The Men and Women Who Cracked the Enigma Code at Bletchley Park

During the war, a branch of British Intelligence, the Government Code and Cypher School, set up shop at Bletchley Park, to decrypt ciphers and codes of the Italians, the Japanese and most of all the Germans, whose Enigma machine, which encrypted all their communications, the team eventually cracked.  The team itself was made up of now-legendary mathematician Alan Turing, codebreaker and classics scholar Dilly Knox, and hundreds of young men and women recruited right out of university and spirited away to a remote estate outside the small town of Bletchley, where they signed the Official Secrets Act which forbade them, during the war or for decades after, from ever discussing their work.  It was work that many of them never fully understood, while all of them bore “the heroism of the long, hard slog and the burden of ugly, painful secrets.”

“It was not just the mentally exhausting prospect of facing, day after day, these groups of random-looking letters, trying to think from every conceivable angle of some sort of logical formula that would bring order to the chaos and make the letters resolve into language,” McKay writes.  “It was also the knowledge that they simply had to succeed.”

However, he continues, “at the higher levels, the cryptanalytic work was intensely enjoyable.”

And so is this book.

If you’re an Anglophile, a history buff, a lover of stories of small communities becoming a tribe, this is the book for you.  If you have any interest in Bletchley Park or codebreaking, this will be your go-to book.  Meticulously researched (the author seems to have read every scrap of paper relating to the subject), The Secret Lives of Codebreakers lives up to its title by evoking the day-to-day lives of the Park residents, from the notorious Turing to a 14-year-old waitress who worked in the dining hall while her sister and mother were also employed at Bletchley Park, doing work they never discussed.  Author McKay has interviewed many of the former codebreakers and he relates, in a lively, sympathetic (and so veddy veddy British) voice their romances, mishaps and social lives.  Thorough in its execution and thoroughly engaging.
