Took me six hours to read it in the end, what a terrible book it was.
Seriously, is there really any need to finish every chapter with some stupidly contrived cliffhanger? Is there really any need to resort to the hackneyed English tally-ho lapsed aristocrat character that American thriller writers seem obsessed with? And can Dan Brown not write a chapter any longer than four pages?

I felt dropkicking it into a burning skip. Actually, scratch that, I felt like dropkicking Dan Brown into a burning skip.
