Rating: WORTHY!
Set in 1954, the story begins with two US Marshals setting out for Ashecliffe Hospital for the Criminally Insane which is housed in an old fort on Shutter Island. On the ferry to the island where the story opens, Teddy Daniels has a new partner named Chuck Aule with whom he has never worked. Teddy is throwing up in the bathroom.
They are sent to investigate the disappearance of a female inmate named Rachel Solando, who evidently murdered her own three children, so the story has all the hallmarks of a locked room mystery. I saw the film made from this novel some time ago and barely remembered it, so my impression was that I didn't like it very much, but I decided to give the novel a go anyway since I'd liked this author's novel Mystic River. After I read this I watched the movie again and liked it, but was not overwhelmed by it.
The novel was good though, and I found that the reader quickly learns that not everything is as it seems here. People appear to be keeping secrets. There are hints that perhaps some radical experimentation is taking place on the island on some of the patients. It doesn't help that real clues are hard to come by, that many of the potential witnesses are literally insane, that Teddy is suffering migraines, and that a hurricane is coming down hard on the island. Worse than this, Teddy has an agenda - to find the guy who he thinks burned down his home and thereby killed his wife, and he thinks Andrew Laeddis is somewhere in Ashecliffe.
It became apparent at a point early in the story that someone was deluding themselves, but I could never tell whether it was going to take the predictable route or if there really was something else going on. It took the predictable route, but that didn't make it any less of a worthy read for me. I enjoyed it and I recommend it.
