Rorate Caeli has a most interesting piece on its site. It reproduces an interview originally published in Inside the Vatican with Fr Charles Murr who knew Mother Pascalina, the famous housekeeper of Pope Pius XII. Fr Murr wrote a biography of her and in the interview he talks about her recollection of events in the Vatican as well as his experiences of Curial politics in the post-Conciliar era.
It makes for very interesting reading, and further confirms many suspicions and indeed interpretations of what happened in those years. It can be seen at EXPOSÉ: New Interview with Fr. Charles Murr on Mother Pascalina, Bugnini, Paul VI, and Other Major Figures
