The film's ending is different from the source novella. In the novella, Ted and Amy survive Mort's attempt on their lives, and Mort dies. It is also revealed that through [[supernatural]] forces, the fictional John Shooter had manifested and come to life from Mort's imagination, and really was the one to commit the murders and arson.
