Query: Unoriginal and weak

This was the first book I have read from Lehane and I was sorely disappointed. The story itself was borrowed from William Peter Blatty's book "The Ninth Configuration" (also a movie). The similarities of the story line are so striking that it makes Shutter Island a poor replication of Blatty's ideas. Completely unoriginal and, for those who have read Blatty's book, predictable about a third of the way through it.
