Naomi Anstruther's undercover operation among the drug gangs, planned carefully by Detective Chief Superintendent Colin Harpur, has ended in a bloody shoot-out. Naomi escapes, but both her ex-boyfriend and her current lover—who shouldn't have been there—are dead. Now the biggest danger to Naomi is a young woman named Esme, who believes that she and Naomi should personally avenge Donald's and Lyndon's deaths.
