Not news to me, might be news to some of you who lurk. All of these stories about Pius XII's mythical collaboration with Hitler didn't get their start until the publishing of a play called The Deputy in 1963 by Rolf Hochhuth. There have recently been reports that the KGB had set out to discredit the pope and the Church. I understand that Hochhuth later admitted that the claims in the play were contrived.
