The housewife who spied for the Russians

Many months ago I was asked by a friend who said that he was reading a book in which it stated that Mr and Mrs Greathead from Oxford were lodging with a Russian spy. What did I know of it? Well never to be one to shrink from a challenge I discovered the daughter of this very Mr and Mrs Greathead and she told me she remembered the lady. She was only young at the time. However she sent me copies of newspaper articles, letters and the story her Mum wrote.
She agreed that I could add it all to the website, well I finally did it tonight. Thanks Larraine
