The Lost Symbol (Spoiler!)

I finally managed to read Dan Brown's 'The Lost Symbol'. Awesome! It was hard to put it down every night. Though it wasn't difficult to guess Malakh's real identity, the book kept me spellbound right till the end. Speaking of which, the end slightly disappointed me. I would have preferred a staircase spiraling down into the bowels of the earth in some far-away ancient cave rather than at the base of some Washington monument. :-(
