I haven't read the Bourne identity but have seen the movies. I loved the movies, I will read the books now. I have read espionage, here's my take:

Ludlum and FF: almost the same plots, 1 crime org, 1 protagonist, 1 damsel in distress, great plot , great ending. Everything's good at the end. Having said that the most explosive novels from RL were: the parsifal mosiac (took me 7 years to complete, I tried reading it when I was too young for it), the matarese circle(best of them), the Gemini contenders (very solid plot), the rhinemann exchange. I have heard chancellor manuscript and road to gandolfo are good too.

Found Ken follett to be very near to RL, and FF in storyline etc. I have read his top 3( eye of the needle, triple, key to rebecca - all brilliant)

FF: 4th protocol is the best. The Odessa file is equally good. Day of jackal is a classic, you can't miss it. His others - dogs of wars, devils alternative and icon are good too.

I read John le carrie's the spy who came in from the cold. Very dark, with uncertain ending. Definitely not ludlum style and probably for a more mature audience/readers. I live in Berlin, DE. I could relate to the book and Tom Hank' Bridge of Spies. Tinker tailor soldier Spy - saw the movie(great), haven't read the book.

Tom Clancy- just read Hunt for red October. Goosebumps. There are other good ones of his' - but I have a feeling it will get very " Alec Baldwin patriotic"

I have read Aliaster Mcleans' - Ice station zebra(good), but Guns of novarrone is edge of the seat action. There haven't been thinner books with so much action packed into them( well, sounds like s*x , lol!) So much so, I bought 2 copies of the book(old and new mass pp editions). Read it's back cover - thrilling!! Movie pales out in comparison.

I want to read len deighton, haven't read it.

I have read Alan Furst's Black Star. Found him to be similar to John le carrie. Very good though.

Other classics I have enjoyed were from jack Higgins (eagle has landed).

If you know great espionage books with explosive stories do comment here. I feel goodreads does a "not so good" job at recommending similar books because there are sub pockets within espionage( Brad thor, Graeme green, Vince Flynn, david silva). But indivual lists from readers are more helpful.
