An autopsy room is where secrets are revealed...or buried. Young Dr. Riley McKay has worked hard toward her career in pathology-and now she has secured a fellowship at the renowned Allegheny County Coroner's Office in Pittsburgh. But her promising future is threatened when suspicious activities incriminate her supervising pathologist, Dr. Nathan Lassiter. Bungled autopsies, concealed evidence, and unexplained wounds accumulate at an alarming rate. When Riley is ignored by her seniors and threatened by Dr. Lassiter, she turns in desperation to Dr. Nick Polchak, the Bug Man, to help her uncover the truth. From a handful of tiny maggots, Nick and Riley begin to unearth the facts, and together they discover that these blunders are not accidents but part of a larger evil that threatens their very lives.
