The order the books were released — the default way to read the series.
NYPD Red is the small, elite squad that protects New York's rich and famous -- politicians, movie stars, visiting royalty -- funded jointly by the city and the businesses that need its discretion. Detectives Zach Jordan and his ex-girlfriend-turned-partner Kylie MacDonald work its highest-profile cases: a killer targeting celebrities at a film festival, a serial bomber with a grudge against the city, murders timed to a papal visit. The premise gives Patterson and Marshall Karp an excuse to stage huge, headline-grabbing set-pieces against Manhattan's glossiest backdrops, while Zach and Kylie's unresolved history supplies the will-they-won't-they thread running underneath the cases.
Patterson and Karp co-created the series and co-wrote its first six novels (2012-2020). Karp then continued it solo from NYPD Red 7: The Murder Sorority (2022) onward, keeping Zach and Kylie's partnership and the squad's celebrity-crime premise intact while writing the later entries independently under the same NYPD Red banner -- a similar handover to how other Patterson-founded series have continued under a single collaborator's byline.
8 novels, from NYPD Red (2012) to NYPD Red 8: The 11:59 Bomber (2025).
