Dennis Lehane is best known for his novels Mystic River, Shutter Island, and Gone Baby, Gone. His latest, World Gone By, is about a character struggling with moral ambiguity while serving in the mob hierarchy in Florida in 1943. He describes it as the final piece of a triptych.
I have always found his books to transcend genre as novels of ideas. He is also a terrific interview.
