The story unfolds against the backdrop of iconic landmarks and historic buildings that dot the nation's capital, including the U.S. Capitol Building, the Smithsonian Institution, and the Washington Monument.

The narrative delves into the hidden chambers, tunnels, and temples beneath the city's surface, revealing a clandestine world of Masonic secrets and ancient wisdom. Key locations such as the House of the Temple, headquarters of the Scottish Rite of Freemasonry, and the National Cathedral play pivotal roles in the unfolding mystery.
