I dunno, Jack. I can't find much information corroborating the Liebreich book, other than an endorsements at ianpaisley.org and similar anti-Catholic Websites. Amazon cites Liebreich's credentials:

Karen Liebreich has a doctorate in history from Cambridge University and a research diploma from the European University Institute in Florence. She has worked as cultural assistant for the French Institute in London, and has been a television documentary researcher and producer for the BBC and The History Channel.

I'm wondering if Liebreich did a legitimate, balanced work of historical research, but the only ones who paid attention to her work were the anti-Catholic extremists. Whatever the case, please remember that the child molestation allegations against Father Stephano Cherubini took place in the 16th century. Far more pertinent is the 21st-century story of Fr. Marcial Maciel Degollado founder of the Legionaries of Christ religious order, father of three illegitimate children, and molester of young seminarians.
