In the heart of New York City, innocent people are being slaughtered in cold blood-by someone wearing a police uniform. As fear grips the streets, rookie officer Jack Forrest becomes the prime suspect after the brutal murder of his own wife. But Jack isn't the killer... and the real threat is far more terrifying. Lieutenant Frank McCrae's investigation uncovers a horrifying truth: a relentless, inhuman force is stalking the city-a man once sworn to serve and protect, now back from the grave and out for blood. As the body count rises and the department closes ranks, McCrae and Forrest must race to uncover the secret behind the badge before the city is drowned in its own blood. From the cult horror film comes a chilling novelization filled with suspense, action, and undead vengeance-Maniac Cop is back on patrol. Based on the screenplay by Larry Cohen
