David Shugarts’ book, “Secrets of the Widow’s Son,” is a guide to Dan Brown’s novel “The Lost Symbol,” much in the same manner as the prior two books he was involved in. Shugarts is a contributor and editor of the two earlier books that revealed many of the historical facts and mysteries in Dan Brown’s books “The Da Vinci Code” and “Angels and Demons.” While caught up in the research involved in the books “Secrets of the Code” and “Secrets of Angels and Demons,” he developed a deep interest in what direction Dan Brown would take in his next blockbuster book. By ferreting out clues in “The Da Vinci Code,” Shugarts was sure the Dan Brown would place his next novel in Washington, D. C. and have the history of the city and its Freemason founders as an integral part of the book. In an unprecedented event, Shugarts released his “Secrets of the Widow’s Son” prior to the release of Dan Brown’s book “The Lost Symbol.” At the time of the writing of Shugarts’ book, the working title for “The Lost Symbol” was “The Solomon Key,” a point of confusion for many who didn’t realize that the title had changed after Shugarts’ book was released.
