Winner of the Edgar Award: A demon is intent on devouring the world—and it’s up to a small group of believers in San Francisco to stop it.

A desperate and terrified old man appears at the office of John Hyatt at the San Francisco Department of Sanitation with a chilling complaint. His house, Seymour Willis insists, is breathing. Hyatt suspects a rat infestation but the truth is worse. Much worse. An ancient demon out of darkest Native American folklore lives within the walls and floorboards of Willis’s home—an all-powerful malevolent being determined to break free and wreak havoc on the City by the Bay.

Soon a tiny cadre of believers in the impossible—including Hyatt, Willis, and a Native American shaman—hold the fate of all humanity in their hands. The monster’s hunger for blood and flesh is insatiable and it is determined to escape its prison and become whole. And once it does, the entire world will be its feeding ground.

A haunted house story like no other—a gory and terrifying tale of demonic possession—this award-winning supernatural thriller by the acclaimed author of The Manitou provides substantial chills on every page. A tale of unrelenting terror reminiscent of the works of H. P. Lovecraft, Graham Masterton’s Charnel House will haunt your dreams long after you’ve turned the final page.
