Detective Chief Inspector Harriet Martens has earned the nickname the "hard detective" -- but she's had to be unyielding to make it in a man's world. It was this toughness that inspired her successful Stop the Rot campaign, that has so provoked local criminals. Now two of her officers have been murdered within hours of each other, both in circumstances suspiciously echoing the words from the Book of Exodus: Life for Life, Eye for an Eye . . . Can Harriet prevent the six deaths that will surely complete the quotation?
