"Tough-but-tender cop Lindsay Boxer" (People) leads the Women's Murder Club in the high-profile murder investigation of a billionaire San Francisco couple. As enemies lurk in the shadows, will Cindy, Claire, Yuki, and Lindsay still be standing when the clock strikes midnight?
​
SFPD Sergeant Lindsay Boxer, Medical Examiner Claire Washburn, Assistant District Attorney Yuki Castellano, and crime writer Cindy Thomas gather at one of San Francisco's finest restaurants to celebrate exciting news: Cindy is getting married.

Before they can raise their glasses, there's a disturbance in the restaurant. A woman has been assaulted.

Claire examines the victim. Lindsay makes an arrest. Yuki takes the case. Cindy covers it.

The legal strategy is complicated by gaps in the plaintiff's memory—and the shocking reason behind her ever-changing testimony.

As Yuki leads the prosecution, Lindsay chases down a high-society killer whose target practice may leave the Women's Murder Club short a bridesmaid . or two.
