Thriller Idea

I want to write a Dan Brown-type conspiracy thriller featuring the three scariest organizations I can think of: the Church of Scientology, Opus Dei, and the international cabal of Leo Strauss followers. The big secret they are vying to variously hide or uncover is that Xenu wrote the Book of Mormon. Also featured will be a secret team of ninja assisins operated by the Committee on Social Thought at the Univeristy of Chicago.
