Mr. Murder

Happily married with two adorable children and a successful mystery writing career, Marty Stillwater considers himself a lucky man. But his comfortable cocoon is shattered when a stranger breaks into his house one rainy afternoon announcing: 'You stole my wife, my life, and my children. I want them back.' Claiming to be the real Martin Stillwater, the madman wages a terrifying campaign to eliminate Marty and recapture his family and life he believes to be his. Even the police are hard-pressed to believe the Stillwaters' harrowing account of what's happening to them, and the family is ultimately left on its own to deal with the menace in Koontz's most horrifying tale of suspense to date.
