4th of July by James Patterson

The world's bestselling detective series has never been more suspenseful. Trapped in deadly showdowns, courtroom trials, and dangerous secrets, the Women's Murder Club must fight for their lives.

In a deadly late-night showdown, San Francisco police lieutenant Lindsay Boxer fires her weapon and sets off a dramatic chain of events that leaves a police force disgraced, a family destroyed, and Lindsay herself at the mercy of twelve jurors. During a break in the trial, she retreats to a picturesque town that is reeling from a string of grisly murders-crimes that bear a link to a haunting, unsolved case from her rookie years.

Now, with her friends in the Women's Murder Club, Lindsay must battle for her life on two in a trial rushing to a climax, and against an unknown adversary willing to do anything to hide the truth about the homicides-including kill again?
