She is a horrible and untrustworthy authoress. She claimed that many popes were Freemasons and that Pope Pius IX was a Freemason. This had been refuted in his own lifetime and he was greatly offended by the accusation. She used Freemasonic writers to back up her claim instead of using Catholic authors. I wouldn’t touch her trashy books with a ten foot pole.
Unfortunately, there is a fair bit of truth in there. It's a shame that it's blended in with the falsehoods.
