Recently promoted and transferred to the homicide division, Inspector Jessica Shepard feels pressure to prove herself -- and what better way than by solving San Francisco's latest murder? However, as Shepard and her partner, Mike Delmarco, soon discover, the victim shared a romantic connection to her. As more of Shepard's ex-lovers turn up dead, her mind starts to become unstable, and she begins to wonder if she could be the very killer she's trying to track down.

When a prostitute is found dead in a Los Angeles skyscraper occupied by a large Japanese corporation, detectives John Connor and Web Smith are called in to investigate. Although Connor has previous experience working in Japan, cultural differences make their progress difficult until a security disc showing the murder turns up. Close scrutiny proves the disc has been doctored, and the detectives realize they're dealing with a cover-up as well.
