I wasn't all that interested in seeing the movie that was recently out, but I decided to read the book because I've slowly become a fan of Dennis Lehane's writing. He's great at depicting different facets of Boston and at evoking a noir atmosphere (and typically does both at the same time). Shutter Island is set on a psychiatric prison hospital on one of Boston's harbor islands. It follows two U.S. marshals who are sent to investigate a patient's disappearance. Although it's more of a traditional mystery than Lehane's novel The Given Day and some of his other short stories that I've read, it's definitely not a traditional detective story. It's really a psychological thriller...and I mean that in a very literal sense.
