Where is Pernille Kurzmann now? Kurzmann still works at Nykbing Falster Hospital. She changed her name when she married Dr Niels Lunden, who helped her uncover Hansen's crimes and also features in the series.

The book documents the story of a real nurse named Christina Aistrup Hansen, who was arrested in March 2024 for intentionally killing patients in southern Denmark. During night shifts, Hansen would dose patients with lethal medication in order to worsen their conditions before trying to "save" them again.
