Extract relating to military intelligence work:
For the Second World War meant his own career was held up again, as he was plucked from King’s [College, Cambridge], having scarcely taken up his Fellowship, to join the code breakers at Bletchley Park. Unlike the much younger Harry Hinsley, Plumb did not cut a glamorous figure, and he consolidated his reputation for being as good at making enemies as friends among his academic contemporaries. But despite his radical politics, he was also beginning to appreciate the good things of life, having been introduced to claret by his college tutor, Sydney Grose, and during his time at Bletchley, his taste for fine wine was further developed when he lodged with Anthony Rothschild.
