The book was dedicated to him.

He is the author of The Stone Puzzle of Rosslyn Chapel (2002), on the enigmatic Scottish chapel and its relationship with freemasonry and the Knights Templar; The Canopus Revelation (2004), on the lore of the star Canopus in ancient cultures; Land of the Gods (2007), on the prehistory of Southern Scotland and the myth of King Arthur; The New Pyramid Age (2007), detailing the most recent discoveries that have changed our understanding of pyramids; and Servants of the Grail (2009), identifying the real people encoded into the medieval Grail legends.
