I listened to this book on tape during my commute after a recommendation from a Goodreads discussion group. This was a very strange book! It began with Teddy, a federal marshall, going to "Shutter Island" which is an island that houses an insane asylum, because a patient had escaped from the institution. Him and his partner Chuck proceed to investigate and search for the patient. There is a real twist to the book, kind of reminded me of "The Sixth Sense". Recommend to any of you who like psychological thrillers!
