Harriet Martens is a tough cop, but she must now muster all her strength to prevent a serial killer completing a gruesome plan of revenge. 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, after all, this toughness that inspired her successful Stop the Rot campaign, that has so provoked local criminals. But now two of her officers have died within hours of each other. Harriet comes to believe both have been murdered - and a disturbing idea follows. For the circumstances of each death echo words from the Book of Exodus: Life for Life, Eye for Eye . . . Has a killer chosen this gruesome ritual to tell Harriet she has been pushing too hard? And if so, can she prevent the six deaths that will surely complete the quotation? Beginning with Tooth for tooth . . .
