In INTERIOR DARKNESS, Peter Straub explores the deepest, shadow-filled corners of his imagination. His world is made up of damaged people --- from the righteous to the depraved, from the working class to the wealthy. No one and no place is safe from the darkness that he reveals. In “Blue Rose,” an adolescent sociopath inflicts secret violence on his younger brother; in “Mr. Clubb and Mr. Cuff,” a stern estate lawyer hires a pair of "Private Detectives Extraordinaire" to investigate and seek revenge on his unfaithful wife; and in “The Ballad of Ballard and Sandrine,” a man and his much younger lover explore their decadent and increasingly sinister fantasies aboard a luxurious yacht on the remotest stretch of the Amazon River.

Twenty years ago, a boy named Jack Sawyer traveled to a parallel universe called the Territories to save his mother and her “Twinner” from an agonizing death that would have brought cataclysm to the other world. Now Jack is a retired Los Angeles homicide detective living in the  hamlet of Tamarack, Wisconsin. When a series of gruesome murders occur in western Wisconsin that are reminiscent of those committed several decades earlier, Jack’s buddy, the local chief of police, begs Jack to help find the killer. But are these new killings merely the work of a disturbed individual, or has a mysterious and malignant force been unleashed in this quiet town?

For four aging men in the terror-stricken town of Milburn, New York, an act inadvertently carried out in their youth has come back to haunt them. Now they are about to learn what happens to those who believe they can bury the past --- and get away with murder.
