Barry Eisler

I am reading the second John Rain book, Hard Rain. The series is about an assassin who specializes in making his hits look like they were natural causes or accidents. Eisler's site is pretty damn good with lots of links and info that give depth to the character and how he composes him.

More authors should have sites like Eisler, especially aithors who write thriller books. One of the best things about reading Warren Ellis is that you can trace where he gets his information from.
