Amazon does a "list mania" thing that might be useful.

The older Robin Cook novels were a good read for the "doctor turns detective" type mysteries. Grisham's earlier "attorney turns detective" novels a worth a look, too.
Are you interested in True Crime novels? "The Onion Field," "In Cold Blood," and "Hocus Pocus" are chilling because they are true.
I read Lehane's first book (Mystic River) and really liked it. Haven't read the second yet.
I have a compilation of the Sherlock Holmes stories and the book is great if you are just wanting a pick up/put down distraction for the moment.
I third the Agatha Christie novels as good reading. I have yet to guess the bad guy even with (or because of) all of the "clues" she drops.
Happy reading.
