Michael Zinn Lewin (born 1942 in Springfield, Massachusetts) is an American writer of mystery fiction perhaps best known for his series about Albert Samson, a distinctly low-keyed, non-hardboiled private detective who plies his trade in Indianapolis, Indiana. Lewin himself grew up in Indianapolis, but after graduating from Harvard and living for a few years in New York City, has lived in England for the last 40 years. Much of his fiction continues to be set in Indianapolis, including a secondary series about , a policeman who frequently appears in the Samson novels, generally in a semi-confrontational manner.
