In this 22nd Kay Scarpetta novel, she is in pursuit of a serial sniper who leaves no evidence except fragments of copper. The fatal shots seem impossible to achieve, the victims appear to have nothing in common, and there is no indication where the killer will strike next. Scarpetta tracks the sniper across several states to the coast, where she dives a shipwreck and finds shocking news that implicates her niece, Lucy, Scarpetta's very own flesh and blood.
