I was going to post on "What Are You Reading Now" but figured this could be a new thread. I am reading Josh Bazell's second novel "Wild Thing" having read the first, "Beat the Reaper" a few weeks back. They are about a doctor, formerly a mob hitman, in the witness protection program. Bazell is a doctor. The novel's are augmented with footnotes, often medical, that add to the story line. The only other fiction writer I'm aware of who used this technique was George-MacDonald Fraser in his "Flashman" novels, works of historical fiction. Any other examples of footnotes in fiction out there that folks could recommend?
