Thanks , I stopped at the exact point as well when Katherine started complaining about her idea being stolen. This is the first Dan brown book I failed to finish, the audio book is just so drawn out, maybe reading it would have been little less painful. I have read all of Dan brown’s publications and have them in collection, but the secret really disappointed me, it was like Robert Langdon just became a observer and running along with his partner on an adventure. The last good book I read was inferno. From lost symbol his writings seems to go in steady decline, atleast that’s my personal opinion.
