In a late-night showdown after a near-fatal car chase, San Francisco police lieutenant Lindsay Boxer has to make an instantaneous decision: in self-defense, she fires her weapon – and sets off a chain of events that leaves a police force disgraced, an entire city divided, and a family destroyed. Now everything she’s worked her entire life for hinges on the decision of twelve jurors.
To escape scrutiny during breaks from her trial, Lindsay retreats to the picturesque town of Half Moon Bay. But soon after her arrival, a string of grisly murders punches through the peaceful community. There are no witnesses and there is no discernible pattern. But a key detail recalls a case Lindsay worked on as a rookie years before – an unsolved murder that has haunted her ever since. As summer comes into full swing, Lindsay and her friends in the Women’s Murder Club battle for her life on two fronts: before a judge and jury as her trial comes to a climax, and facing unknown adversaries who will do anything to keep her from the truth about the killings – including killing again.
Detective Lindsay Boxer is jogging along a beautiful San Francisco street when a fiery explosion rips through the neighborhood. A townhouse owned by an Internet millionaire is immediately engulfed in flames, and when Lindsay plunges inside to search for survivors, she finds three people dead. An infant who lived in the house cannot be found – and a mysterious message at the scene leaves Lindsay and the San Francisco Police Department completely baffled.
Then a prominent businessman is found murdered under bizarre circumstances, with another mysterious message left behind by the killer. Lindsay asks her friends Claire Washburn of the medical examiner’s office, Assistant D.A. Jill Bernhardt, and Chronicle reporter Cindy Thomas to help her figure out who is committing these murders – and why they are intent on killing someone every three days.
Even more terrifying, the killer has targeted one of the four friends who call themselves the Women’s Murder Club.
While the investigation rages furiously, Lindsay works very closely with a federal officer assigned to the case. At the same time, she learns that one member of the Women’s Murder Club is hiding a secret so dangerous and unbelievable that it could destroy them all.
