The 24th Hour — James Patterson; Maxine Paetro

As enemies lurk in the shadows, “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 -- 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.
