Audiobook The Nurse: Inside Denmark's Most Sensational Criminal Tria, written by Kristian Corfixen. In the early hours of March 2015, the police receive a call from a nurse at a provincial Danish hospital. She suspects her colleague is deliberately killing patients and fears that it has just happened again. Soon, several witnesses reveal that they too suspect the same nurse of poisoning patients; some have been harbouring their suspicion for years.
