One of my great-grandmothers was one of Anthony Blunt's maternal aunts . My family thought of him as a shy but charming man who had deep knowledge of old masters & never knew about his politics or his secret activities , esp in MI5 . The revelation in 1979 of his espionage was shocking .
I gather from the late Monsignor Alfred Gilbey that he was an open Communist at Cambridge , keeping company of the CambridgevApostles' Club , but that the University authorities were more concerned about Fascism including the Fascism promoted by Blunt's 3rd cousin Sir Oswald Mosley Bt .
The book mentions my gt-gt-grandparents & their residence at Petersham , setting a context f Blunt's parents .
