33 keys to unlocking The lost symbol

the long version

From a Dan Brown expert, a handy, reader-friendly guide to 33 critical topics covered in The Lost Symbol, including photos, illustrations, and reference links for further exploration. There's so much information and so many facts contained in Dan Brown's thrilling new page-turner that many readers need a quick reference guide to the history, geography, art and architecture, cryptology, science, people and places in the novel. Professor Beyer, who has taught seminars and produced on-line texts to Brown's The Da Vinci Code and Angels & Demons, started to work on this Lost Symbol companion guide three years ago in anticipation of its subject matter.
