As someone who is half way through 'The Turn of the Screw'; I would just like to say that Dan Brown is a better writer than Henry James (imho).
This is HJ in full flow:
"It produced in me, this figure, in the clear twilight, I remember, two
distinct gasps of emotion, which were, sharply, the shock of my first
and that of my second surprise. My second was a violent perception of
the mistake of my first: the man who met my eyes was not the person
I had precipitately supposed."
