A novel of compelling suspense. Professor James Lowry didn't believe in spirits, or witches, or demons. Not until a gentle spring evening when his hat disappeared, and suddenly he couldn't remember the last four hours of his life. Now, the quiet university town of Atworthy is changing - slightly at first, then faster and more frighteningly each time he tries to remember. Lowry is pursued by a dark, secret evil that is turning his whole world against him while it whispers a warning from the shadows: If you find your hat you'll find your four hours. If you find your four hours then you will die... "A classic tale of creeping, surreal menace and horror... one of the really, really good ones." — Stephen King
