Here's an interesting story from Salt Lake City news provider KSL.com which supports the idea that Dan Brown will cover Mormonism in his next book. The report says that Dan Brown has spent serious time in Salt Lake City investigating both the Masonic landmarks in the area as well as the Mormon history.

Aaron Wilhelm, Dan Brown's host 2004: "He was, of course, very interested in the symbology on the Mormon temple...he was interested in the pentacles and the suns and the moons and the stars and all that. So, I gather his primary interest was to sort of see the Mormon embellishment of masonry as it exists, in his mind, of course..."

...Dan Brown, no doubt, has found fascinating examples of Masonic symbolism laced with early Mormon history. He returned to Salt Lake City this year and church leaders allowed him access to the historic archives.

I had already predicted a possible Mormon angle in the new novel, due to a hint on his website about the phrase 'Is there no help for the widow's son' - which is a Masonic distress call, and was allegedly the last thing that Mormon founder Joseph Smith said before his murder by a mob.
