The lost symbol (Random House)

Robert Langdon flies to Washington after an urgent invitation to speak in the Capitol building. The invitation appears to have come from a friend with copper-bottomed Masonic connections, Peter Solomon.

But Langdon has been tricked: Solomon has, in fact, been kidnapped, and (echoing the grisly opening of the last book) a macabre mutilation plunges Langdon into a tortuous quest.His friend’s severed hand lies in the Capitol building, positioned to point to a George Washington portrait that shows the father of his country as a pagan deity.The ruthless criminal nemesis here is another terrifying figure in Brown’s gallery of grotesques: Mal’akh, a powerfully built eunuch with a body festooned with tattoos.Mal’akh is seeking a Masonic pyramid that possesses a formidable supernatural power, and a pulse-pounding hunt is afoot, with Langdon stalled rather than aided aby the CIA.
