The year is 1954. U.S. Marshal Teddy Daniels and his new partner, Chuck Aule, have come to Shutter Island, home of Ashecliffe Hospital for the Criminally Insane, to investigate the disappearance of a patient.
Multiple murderess Rachel Solando is loose somewhere on this remote and barren island, despite having been kept in a locked cell under constant surveillance. As a killer hurricane relentlessly bears down on them, a strange case takes on even darker, more sinister shades—with hints of radical experimentation, horrifying surgeries, and lethal countermoves made in the cause of a covert shadow war. No one is going to escape Shutter Island unscathed, because nothing at Ashecliffe Hospital is what it seems. But then neither is Teddy Daniels.
Although I have suspected who Teddy really is from the clues left by the missing inmate and when he finds and has a conversation with her in a cave, it is still a great psychological thriller and it kept me guessing the whos and whys up to the end. The ending has all the answers although Teddy's fate is a bit vague and it is up to the readers to draw their own conclusion.
