"Actually, with one alleged exception, the links of King’s dons with intelligence were with the British rather than the Soviet secret services. Kingsmen, headed by the small, roly-poly later professor of ancient history, F. E. Adcock, had set up the British codebreaking establishment in the First World War, and at least seventeen King’s dons were recruited by Adcock for the much more famous establishment at Bletchley during the Second World War, including probably the only genius at King’s in my undergraduate years, the mathematical logician Alan Turing, whom I recall as a clumsy-looking, pale-faced young fellow given to what would today be called jogging."
