When a husband died after a long illness, and under suspicious circumstances, it was this episode's guest, Forensic Chemist Maggie Baron, who was tasked with searching for traces of poison with a suspected killer looking over her shoulder.

All before her 25th birthday, Maggie had held the hands of killers, armed robbers, and violent offenders…not in comfort, but in the name of science.

In this episode, Maggie reveals to host Liz Porter what it’s like to be alone in a room with someone who’s just ended another person's life, and unpacks an arsenic poisoning investigation that reads more like fiction than fact.
