Recent Release, "Knock - Knock," from Fulton Books Author Paul Morrison, Recounts the Intense Hunt for a Serial Rapist Terrorizing New York City Throughout the 1990s

Dobbs Ferry, NY, September 15, 2026 --(PR.com)-- Paul Morrison has completed a new book, "Knock - Knock," a firsthand account of the relentless pursuit of a dangerous predator who posed as a maintenance worker to gain access to his victims' homes. When a cunning rapist begins targeting young women across New York City, invading their residences under the guise of performing repairs, the stakes become impossibly high. For nearly a decade, this elusive criminal evades capture despite an increasingly desperate manhunt, earning the nickname the Knock-Knock Rapist for his modus operandi while detectives refer to him simply as Citywide 6.

As a decorated NYPD detective with nearly four decades of distinguished service, Morrison brings unparalleled credibility and insider perspective to this account. His career, spanning from the challenging 44th Precinct in the Bronx to the elite Special Victims Squad, established him as an expert in sex crimes investigations. His decorated record—including the Police Combat Cross, the Department's second highest honor—and his eventual promotion to Detective First Grade demonstrate his exceptional skill and unwavering commitment to justice. Now retired after 39 years of service to the city, Morrison draws upon his vast experience to tell this consequential story.

"Knock - Knock" reveals the obsessive determination required to pursue such an elusive criminal, taking readers through the psychological and tactical battles waged by the task force assembled to stop him. As Morrison traces the suspect's brazen pattern of narrow escapes and taunting evasions, readers discover the human cost of hunting monsters who operate with cunning street intelligence. This arresting narrative exposes both the vulnerability of victims and the indomitable resolve of those dedicated to their protection, ultimately exploring what drives a detective to risk everything in pursuit of justice.

"This case consumed my life for years," said Morrison. "Writing about it allowed me to finally share the complete story—not just the investigation, but the emotional toll it took on everyone involved. I hope readers understand both the gravity of these crimes and the extraordinary effort required to stop predators like this from terrorizing our communities."

Published by Fulton Books, Paul Morrison's gripping work offers readers an unflinching examination of real crime investigation. This account demonstrates the resilience of survivors and the dedication of law enforcement professionals who refuse to abandon the hunt for justice.

Readers who wish to experience this riveting work can purchase "Knock - Knock" at bookstores everywhere, or online at the Apple iTunes Store, Amazon, Google Play, or Barnes and Noble.
