In the summer of 1985, a brilliant young British DNA scientist Helena Greenwood is found murdered in her front garden in a quiet suburb in California. The police believe they know the killer’s identity but there’s no evidence against him, and the only thing linking him to the crime is the fact he’d been charged with sexually assaulting Helena just a few months previously. Fifteen years later the case is reopened and after a breakthrough in DNA evidence, David Paul Frediani is re-investigated, convicted and sentenced to life in prison. It was almost as if Helena was pointing to her killer from beyond the grave, using the very scientific technology she had spent her life working on. Author Samantha Weinberg has been fascinated by this case, writing an award-winning book about the tragic sequence of events. She’s spent time with the man convicted of the murder and was utterly convinced of his guilt. But, in 2018, she received a letter from a jailhouse lawyer, a fellow inmate of Frediani that would blow the case apart. Together, they reopen the investigation, embarking on a shocking journey to discover the truth - in the process uncovering systematic failings and abuses in the American criminal justice system.
