Washington DC: Harvard symbologist Robert Langdon is summoned at the last minute to deliver an evening lecture in the Capitol Building. Within moments of his arrival, however, a disturbing object – gruesomely encoded with five symbols – is discovered at the epicentre of the Rotunda. It is, he recognises, an ancient invitation, meant to beckon its recipient towards a long-lost world of hidden esoteric wisdom. Langdon finds himself quickly swept behind the facade of America’s most historic city into the unseen chambers, temples and tunnels which exist there. All that was familiar is transformed into a shadowy, clandestine world of an artfully concealed past in which Masonic secrets and never-before-seen revelations seem to be leading him to a single impossible and inconceivable truth.
The story is interesting and although there is a wealth of information to process, the storyline can be followed easily and sounds feasible most of the time. I found the strand around Ma'lakh fascinating and surprising. However, once the fast-paced action ends the book drones on for too long to solve the remaining mysteries.
