Lehane is the author of Mystic River, the book on which the movie with the same name was based, starring Sean Penn, Kevin Bacon and Tim Robbins, and directed by Clint Eastwood. Besides Mystic River, Lehane is the author of a series of five novels based on a detective couple, Patrick Kenzie and Angela Gennaro, who live and work in Dorchester, one of the worst Boston neighborhoods (and where Lehane was born and raised).
