Despite being dead for over a year, famous author Agatha Christie saved a baby’s life in 1977.
Her novel The Pale Horse described thallium poisoning so well that a nurse who’d been reading it was able to diagnose a sick infant, who had doctors stumped.
The baby was immediately tested, they found traces of thallium, doctors changed treatments, and her life had suddenly been saved by a 16-year-old murder mystery novel.
