Marshall Karp

MARSHALL KARP co-created and co-authored the first six books in the #1 bestselling NYPD Red series with James Patterson. Starting with NYPD Red 7: The Murder Sorority (PW starred review), Marshall became the sole author of the series, which features Detectives Kylie MacDonald and Zach Jordan as members of an elite task force dedicated to solving crimes committed against — and sometimes by — New York City’s rich and famous.

His latest, Don’t Tell Me How To Die (March, 2025), is a razor-sharp domestic thriller about a dying woman’s desperate mission to handpick her husband’s next wife—and she’ll stop at nothing to get the job done.

He is also the author of the critically acclaimed Lomax and Biggs Mysteries featuring LAPD Detectives Mike Lomax and Terry Biggs, who work homicide out of the Hollywood Division.

After a successful career in advertising, Marshall’s first mid-life crisis transported him from New York to LA, where he wrote and produced numerous TV sitcoms and a feature film, Just Looking, a coming-of-age comedy loosely based on his own embarrassing teenage years. It was during his time in Hollywood that Marshall met many of the people he kills off in his novels — a cathartic yet perfectly legal way for a writer to exorcise his demons.
