A true crime show focusing on poison as the weapon of murder
About Poisonous Liaisons
Poison is the method of murder in this true crime show. Killers use various substances to murder victims ranging from romantic partners, to co-workers, to family members, and they sometimes elude the authorities until they attack a new victim and investigators get suspicious.
Featuring many historical cases from periods when pathologists didn’t routinely test for poisons, Poisonous Liaisons includes cases from the UK, US, and Australia by both women and men, including many serial poisoners.
Each episode details two cases through the stories of detectives, medical examiners, and other experts, such as historians, criminologists, forensics professors, and retired detectives. Episodes exclude interview or trial clips, keeping the descriptions of cases succinct.
