World War II spies
This news story about Basil Liddell Hart running around London telling all that he knew the plans for D-Day made me wonder whether he had anything do with the famous Daily Telegraph cross-word puzzles which revealed details of the codewords used in the landings.Aside from it being about D-Day, there's not much else to back up that thought. However also revealed today was that Lady Howard of Effingham was suspected of being a German spy. And the crosswords were compiled by a headmaster from a school in Tulse Hill, South London, that had been moved to Effingham for the duration of the war. I must be on to something.
