When Scott Wolter began investigating mysterious artifacts, he started to notice one unique symbol appeared on many of them. The symbol, now known as the "Hooked X", baffled researchers who couldn't make sense of it. As Scott's investigation into the origins of the symbol unfolds, he realizes its use is unique to just two notoriously secret groups--the Knights Templar and their modern day brethren, the Freemasons. Used in secret codes, cryptic ciphers and even the alleged tomb of Jesus himself, the symbol could be the key to understanding two of the biggest mysteries of all time--exactly what the Holy Grail is, and where it's hidden today.

The Newport Tower is considered by many to be the most mysterious structure in the United States. Some people think it's a colonial era windmill or perhaps all that's left of an early water tower, but Scott Wolter is convinced it's something far more significant.

Now, he's dead set on proving his theory. While planning an elaborate laser light show designed to illustrate the Tower's miraculous features, Scott discovers something else significant that ties this structure--and the Templar's modern day initiates--to one of America's most visited and most treasured icons.
