NYPD Red 4 by James Patterson, Marshall Karp

A jewel heist. A murdered actress. A killer case for NYPD Red.
In a city where crime never sleeps, NYPD Red is the elite task force called in when a case involves the rich, famous and connected. Detectives Zach Jordan and Kylie MacDonald are the best of the best - brilliant and tireless investigators who will stop at nothing to catch a criminal, even if it means antagonising the same powerful people they're supposed to be helping.

When a glitzy movie premiere is the scene of a shocking murder and high-stakes robbery, NYPD Red gets the call. In a hunt that takes Zach and Kylie from celebrity penthouses to the depths of Manhattan's criminal underworld, they have to find the cold-blooded killer - before he strikes again.
