Like Water for Murder : When the body of New York’s top real estate agent washes up on the shores of Rockaway Beach along with several dead sharks, Mac and Inspector Quinn Shelby uncover a twisted trail of evidence that includes a shark-topsy and a decadent chocolate fashion show. The evidence grows when a second real estate agent turns up dead, connecting the deaths to an attorney, who was murdered a few months back. Mac and the team soon realize they’re after a serial killer, a cab driver who moonlights as a predator. Now they have to stop him before his next victim could be the next person who rides in his cab.
