As zahymaka pointed out Ludlum's books always revolve around a "non-person"-impossible feats.His style is to create a character that cannot exist:This might sound too critical but Robbie shoots himself in the foot by using characters that are at the centre of a circle and every other person works in perfect harmony for or against the Hero.
Take the case of "The Icarus Agenda".It is inconceivable that anyone had such a smooth flow as Kendrick did.
what do I mean? the goodguys were all focused on helping Kendrick and all the bad guys were anti-kendrick.we did not have anyone in between.
In my humble opinion Weingrass and Bollinger were the only perfect-non-perfect characters.

anyways Uncle Bob does a great work,

John Grisham absolutely gripping.

I am guilty of posting without reading.I didn't know Ludlum is Late.
@zahymaka I read just read your points and I think you hit the nail squarely.
Interesting posts from everyone though.
