That's why I'm a little disappointed. I read The Prometheus Deception, The Ambler Warning and The Rhinemann Exchange and they all have a different feel to them. What excites me most about these books is the psychology of it. How you can look at someone and immediately know if he's a normal person or professional killer. How you can be unseen in a crowd despite cameras everywhere and people tracking you. And that seems a bit forgotten in Bourne Identity.
Love the movies though.
Wow, so you are saying his other stuff does the spy mind games EVEN BETTER?

Haha, here was I loving Jason Bourne books exactly for that, while you say its his weaker stuff in that regard, hehe (I really hope you are right, because that means I have alot to look forward to). But seriously, the Bourne books are really great, the second in China is good, by the first one (and 3rd one so far) regarding his tit for tat mind games and chase after Carlos is IMMENSE stuff IMO.
Thats why the Movies even if they are lovely, are quite poor in comparison, they somehow not only ignored an epic character like Carlos the Jackal, but alot of the finer details of this spy game.
P.S Not as elaborate as Jason Bourne stuff, but if you like spy action thrillers like these (and more asian oriented), I would highly recommend John Rain book series. They are making a movie about him soon.
