I'd heard of Doreen before, but only in the Bletchley Park context. Had no idea about her other persona.
. . . and you heard of her Bletchley Park work from where please?
Either the TV programme that there was on Bletchley Park a few years back, or in an article on the work there. It would only have been a name in a list, rather than anything more detailed.
Thanks
