This is the latest addition to Dan Brown's million-copy bestselling series of novels about the Harvard symbologist Robert Langdon, The Lost Symbol caused a sensation around publication in September. Behind The Lost Symbol is the complete guide to the book, illuminating the text for new readers and devotees alike. Following the tried and tested A-Z format of our earlier guides, all the fascinating entries are cross-referenced to other articles as well as to Brown's novel and its prequels. Behind The Lost Symbol will also include eight pages of colour plates. Subjects covered are the secretive (and, to some, sinister) world of Freemasonry and the influence it had on America's founding fathers, the Masonic symbolism found in, for instance, the US one-dollar bill and the architecture of Washington DC. Behind The Lost Symbol is the unmissable handbook for any reader who wants to delve deeper into the mysteries, science, symbolism and historical contexts of Dan Brown's fiction. Tim Collins is the author of several bestselling non-fiction titles, most recently The Little Book of Twitter.
