Introducing: DOUBT: The case of Lucy Letby hosted by Amanda Knox

It was a case that shocked the United Kingdom and the wider world. Lucy Letby, a young nurse, was found guilty of murdering premature babies.

Host Amanda Knox asks if this case is really as open and shut as the world believes or if – in fact – there is reasonable doubt.
