What “Who Is 67” Means In Shutter Island

The meaning of “Who Is 67” is the key to all the mysteries in Shutter Island — here’s how. On the surface, Martin Scorsese’s Shutter Island is about a U.S. Marshal, Edward “Teddy” Daniels, who sets foot at the Ashecliffe Hospital for the criminally insane with his partner Chuck to investigate the disappearance of a patient named Rachel Solando. However, as the movie gradually removes the tapestry around the island’s secrets by hinting that Teddy took up the case because he believes that his wife Dolores’ murderer, Andrew Laeddis, is on the island, it becomes evident that almost nothing in the movie as it seems.
