Antichrist Conspiracy, by Edward Hendrie
This is a great site. It talks about the relationship between Catholicism and Zionism...it takes you through history.
You can download the free ebook in .pdf format (which I have done; it's stored on a CD) or you can read the .html version online. You can also download the .html.
This guy has done his homework and it's one of my favorite sites. It takes you behind the scenes.
