A Deadly Cover

A graduate school student unwittingly uncovers a clever illicit drug manufacturing scheme including a production process that creates a toxic environment causing nerve damage in several workers. When a neurologist friend of the student meets one of the workers in her clinic, she and her friend recognize a serious pattern of toxicity and bring the evidence to the attention of the company responsible for the production site. But a company insider, currying favor with the drug merchants, tips them off to the threat which sets in motion a cover-up with deep and dangerous consequences.
