But nothing can prepare her for the shock of recognition. The victim is Warren Jacobi, Lindsay's one-time partner who rose to chief of police.
A top investigator until the end, Jacobi managed to leave Lindsay a clue.
As they follow a trail of evidence along the west coast, the Women's Murder Club pledges to avenge Jacobi's death before the killer can take another one of their own.
