Shutter Island by Dennis Lehane

Shutter Island is a 2003 novel written by Dennis Lehane. A film adaptation of the novel directed by Martin Scorsese was scheduled for release in October of 2009 but was pushed back until February 2010.

In a masterful departure from the Boston-based hard-boiled mysteries he's known for, the "New York Times"-bestselling author of "Mystic River" offers an atmospheric psychological thriller set in a 1950s asylum for the criminally insane.
