Aren’t I glad to hear this? According to an article at Seacoastonline his book – working title "The Solomon Key" – is rumoured to be released on Sept 18, since that date has some connection to Freemasonry. The Solomon Key will feature the Freemasons and is set in Washington D.C. I’m going to take a guess now as to some details of the book. I’m pretty sure that the scavenger hunt (and there will be one undoubtedly) will lead Langdon and his female sidekick along the whole east coast, all the way across continents to the Peruvian coast (Nazca lines!), then on to Rennes-le-Chateau until they end up in Munich. There they will find the grimoire in the Löwenbräukeller where it was hidden by the Nazis only to have it snatched away by a descendant of a Rosicrucian leader who wants the book for his own evil purposes. The exotic or homely locations will deceive the reader into believing they read a completely new book when in reality they just forked out whatever it costs for a warmed-up version of Langdons earlier adventures.
