The latest installment of the Women?s Murder Club series begins on a ferry ride across the San Francisco Bay. It?s a picture-postcard day until a gunman opens fire without warning or reason. Several of his victims are killed instantly; some are seriously wounded. Among the victims is a member of the Women?s Murder Club. Even if that weren?t the case, Inspector Lindsay Boxer would be in a rush to find the guy before something sets him off again. In another part of the city, at least two people in a minivan abduct a five-year-old girl and her nanny off the street in broad daylight. No ransom note is forthcoming; and police and parents fear the worst when the body of the nanny, is found. And a certain apartment building experiences an escalating set of problems. It begins with anonymous threatening notes placed under doors, and then continues with the death of small pets. Boxer and her partner get involved when the violence includes trashed apartments and the deaths of tenants.
