They were recruited with one common aim: to unlock the secrets of Enigma, a machine that concealed Germany’s war plans in a seemingly unbreakable code. If Enigma could be penetrated, everything H****r plotted could be known in advance. At Bletchley Park, there unfolded one of the most astonishing exploits of the Second World War.
