In this gritty police procedural set in sunny Los Angeles, one detective retires just as his daughter joins the force--but when a serial killer case goes awry, they both have work to do.

When Cassidy Clarke joins the LAPD, she doesn't plan on following in her father's footsteps. Veteran detective Bill Clarke has big shoes to fill, but Cassidy has her own path to forge through the department's tarnished reputation.

She's just getting started when a string of murders plagues the city: Young women are being strangled in their homes. The media incites an uncontainable frenzy. And no matter how many newspapers they're splashed across, the Hollywood Hit Men are no closer to being found.

While Cassidy takes to the streets, Bill is knee-deep in cold cases--and conversation with another killer. He's sure that Tyler Derby committed more murders than they've pinned on him, and Derby's convinced that, without his badge, Bill is no different from him.

As their investigations escalate, Cassidy and Bill find themselves embroiled in a dangerous game without a playbook. And if they can't figure out the rules, their reputations aren't all they could lose...
