True crime fans often have a pet case that haunts them above all others—one that keeps them returning to the clues, again and again, in search of an answer. I have a few such cases myself, but it only recently occurred to me that I also have a shortlist of obsessed-over medical mysteries. Fatal familial insomnia. Munchausen's. The 1951 Pont-Saint-Esprit mass poisoning, which inspired the 2023 novel, Cursed Bread.

Criminal mysteries and medical mysteries have some eerie analogies. In the broadest strokes, crimes have victims, clues, suspects, and trials; diseases have patients, symptoms, differential diagnoses, and prognoses. As the incidence of chronic illness has risen, so too have the number of patient memoirs that seek to advocate for sufferers amid a dearth of answers from the medical establishment. Alongside these intimate accounts are fascinating journalistic narratives that listen like detective stories, where the investigation takes place across entirely human landscapes. There may be blood but also heart and plenty of brains. The stakes are high and the twists keep coming in these riveting medical mysteries.
