In this episode of Medical Media Mixer, we break down Postmortem by Patricia Cornwell, the novel that introduced forensic icon Dr. Kay Scarpetta. We explore how a rare metabolic disorder — Maple Syrup Urine Disease — becomes the key medical clue that exposes a serial killer, and how Scarpetta weaponizes forensic science and the media to bring him down. We also preview the upcoming Prime Video series Scarpetta and why this story still resonates decades later.
