Amanda Knox did not go looking to spend two years diving into the case of Lucy Letby. She says Lucy Letby found her. Letby is the British neonatal nurse convicted for the murders of 7 babies and attempted murder of seven more at the Countess of Chester Hospital. Knox was convicted of the murder of her roommate in Italy and spent years in prison before the Italian Supreme court threw out the verdict. Since then, she's worked to explain how narrative about a suspect can shape public opinion and even how the police investigate crimes. Knox takes on the case of the woman branded the UK's worst serial killer in a podcast that doesn't try to determine guilt or innocence, but looks instead at how evidence is interpreted, how narratives harden, and why questioning assumptions can be essential to pursuing justice. The podcast is called Doubt: The Case of Lucy Letby.
