Two US marshals, Teddy Daniels and Chuck Aule, arrive at Ashcliffe hospital for the Criminally Insane on Shutter Island in Boston Harbour to search for an escaped child murderess, Rachel Solando. Teddy has a personal reason for wanting to be on the island: He knows this is where the man who killed his wife, Andrew Laedis, is imprisoned.
In Shutter Island Lehane uses a similar device to one he previously used in Gone Baby, Gone: the first three quarters of the book are a procedural as Chuck and Teddy conduct their hunt for the missing Rachel. In the final quarter the true nature of what has been going on is revealed.
There is some debt to Sophicles’ Oedipus Rex in this novel as Teddy finds his investigation coming closer to home than he could possibly have imagined. The result is a compelling novel with the final twists elegantly delivered.
