Trace

Trace by Patricia Cornwell

Against advice from her niece Lucy, Kay Scarpetta answers a request to return to the Richmond medical examiner's office, the same office from which she was fired, to help with the sensitive case of a dead teen. When she and Pete Marino arrive, they find the new medical examiner to be a vituperative, uncooperative martinet and the office that Kay ran so efficiently in chaos. Two murders, oddly linked, demand their attention.
