You never know - after all the letters and official Biography were that much closer to the time of the War (and cold war) to have to be discreet. And the Bletchley Park people had to be beyond discreet. One was more or less sent a white feather by his old headmaster in a letter telling him he was disgrace for not being in uniform and had to take it on the chin since he could not explain the vital significance of his "safe desk job".
