It's a bitterly cold January day in 1976. Gus Breach, the Chief of Police, his three deputies, and Frank Lewis the town mortician, have no idea that the discovery of a strangely dressed, headless and bloodless corpse lying on a deserted mountaintop road, is about to plunge them and the residents of Kulpsville, Pennsylvania, into a holocaust that cannot exist by any reckoning of human experience. A desecrated grave, strange markings in the snow and signs of a violent struggle, all push Breach's former experience on the Pittsburgh Homicide Squad past the limit. A few rejected memories of a similar event trigger his intuition, and the old cop's blood freezes as his instinct "To Protect and To Serve" is thrown into high gear. Brutal murder after brutal murder forces the Chief to call in the State Police and then the Army, but to no avail. All weapons are useless against the floating patch of darkness that conceals the NightShadow monstrosity within. Only when the aid of Abraham ben Yakov, a retired psychiatrist, is enlisted, can the horror be met head on. He alone knows the secret about NightShadow.A secret that involves a conspiracy formed on both sides of the grave; and an enemy he knew throughout his life he would one day have to face. and try to destroy. Accompany Breach, Yakov, and the valiant few as they confront the madness that is NightShadow-that is, if you dare.
