http://www.msnbc.msn.com/id/12084683/ Michael Baigent is investigating a grisly crime. He’s tracking down leads, digging for clues, and trying to shed new light on a cold case— a case that is 2,000 years old. And this isn’t just any case: It is perhaps, the most well known story in history—the crucifixion of Jesus. Sara James, Dateline correspondent: You believe that much of what we think we know about Jesus is a lie? Michael Baigent, author: It’s a lie. It’s an obvious lie. Hard to imagine? Author Michael Baigent has captured readers’ imaginations before with a provocative non-fiction work in which he claimed Jesus was married. Some of the same ideas appear in “The Da Vinci Code” by Dan Brown. In fact, he sued Brown’s publisher for copyright infringement. Brown and his publisher strongly deny they did anything wrong. A decision is pending in the case. Now, Baigent has a new book, "The Jesus Papers," with an even more controversial premise which challenges the conventional story about Jesus. James: So basically, you’re asking anybody who is a Christian to question their fundamental beliefs? Baigent: Absolutely. James: Some might call your position heresy. Baigent: I should hope they would.
