@izzythepush,
Yea, re John Paul I.
I'm not a conspiracy person, as people are too stupid to organize (I'm kidding, I'm kidding) but who knows - that was at least an odd episode.
I read a book that affected me about Pius XII, whom I didn't much like anyway, by a naturally biased guy (former head of the Yugoslav red cross looking for help re the ustache) that wrote some interesting stuff re Cardinal Montini and the papal Pacelli, which I took with a grain of salt but also listening, as his descriptions made sense. That's an oldie, Spy in the Vatican.
