Summary: The most prolific poisoner of all time couldn’t possibly have been a woman. Right??! Goeie Mie, “Good Maria,” was such a selfless and kindly nurse that desperate folks in 19th-century Leiden called her when they were sick, knowing she’d come even if they couldn’t pay. But they got worse…and worse, and usually died in misery. Goeie Mie had life insurance on all of them. Travel on location to Leiden, The Netherlands with Katie in this spooky Halloween Special!
