I, too, am a Chabon fan. If you were ever a superhero comic book fan, you will notice comic homages in most of his work, and not just in K & C. Not bad for a Pulitzer-winner.
Sanford is great, so Thomas Harris if u like menical villians that kill and kill and don't stop untill they are dead, lol. Anybody read Michael Cryton?
Currently im not reading anything all, i do have a copy of Jean Paul Satre's :Anti-Semite and Jew that i need to dust off the shelf. Its about his take on being assimilated with the Gentiles.
Westlake's funny stuff is always funny. Check out his Dortmunder series, too.
By the way, he also writes the Parker series under the pseudonym Richard Stark. Dark, not funny, stuff. The Mel Gibson movie Payback was based on this, but his character name was changed to Porter for reasons I can't fathom.
