NYPD Red 3 is a thriller novel written by James Patterson and Marshall Karp.
Official description:
Hunter Alden, Jr., a billionaire businessman, has it all: a sexy wife, a brilliant teenage son, and an ever-growing fortune. But his perfect life shatters one horrific night when he discovers the severed head of his chauffeur, stuffed in a bag marked, in blood, with his son's initials. Now his son is missing, and the price to get him back might be too high—even for one of the world's richest men.
When NYPD Red, the elite task force for New York City's most high-profile crimes, takes the case, Detective Zach Jordan and his partner—and ex-girlfriend—Kylie MacDonald have never seen anything so unspeakable. As the investigation continues, Zach and Kylie realize that the closer they get to the truth, the more their own lives are in danger. NYPD RED 3 is the next sensational thriller by James Patterson, the man Ian Rankin hails as "The Boss."
