The Closed Island - Dennis Lehane

The closed island novel carries with it a kind of symbolism. The critics found a great similarity between Ashcliff Hospital and the Nazi Dachau Camp, which was famous for mysterious incidents and illegal methods. The difference between the hospital and the camp is that the hero failed to liberate the hospital, not only that, but it turns out that he is one of the patients and he is living in a state of schizophrenia.
