Washington DC is used to hordes of eager tourists, brandishing guidebooks and rushing around the sights, but it is bracing itself for a different influx this week – and a potentially hostile one.
From Tuesday, when Dan Brown unveils the long-awaited sequel to his blockbuster novel The Da Vinci Code, fans are expected to descend on the US capital to gawk at the locations featured in it. They swarmed to places in Britain, France and Italy mentioned in Brown's previous works. The new book, The Lost Symbol, is set largely in Washington and will give the reader a picturesque tour of the seats of American power. But it is also expected to reveal a more mysterious side to the city by exposing the influence that freemasonry exerted not only on the design of Washington DC but on the founding fathers .
