The 6th target

When a horrifying attack leaves one of the four members of the Women's Murder Club struggling for her life, the others fight to keep a madman behind bars before anyone else is hurt. And Lindsay Boxer and her new partner in the San Francisco police department run flat-out to stop a series of kidnappings that has electrified the city: children are being plucked off the streets together with their nannies-- but the kidnappers aren't demanding ransom.
