The Chief Medical Examiner of the City of New York——a man of great privilege——is acting strangely and no one knows why in this mystery/thriller that re-tells the old tale of Jekyll and Hyde with a diabolical twist. Not even his best friend or his wife or a tenacious NYPD detective can explain why Dr. Jenkins has changed so dramatically, but all roads lead to Mr. Hyde, his right-hand man, who suddenly disappears just as Jenkins undergoes a strange personality transformation that could easily end in death.
