Malcolm Webster seems like a well-intentioned, upstanding member of society - a loving husband and a competent nurse. The death of his first wife, Claire, is thought of as a tragic accident for years. But really, Webster is a murderous psychopath - he's desperate for money and keen to kill for it. They are the men and women we trust with our lives, but there are rogue medics who use their medical know-how to commit crimes - they try to get away with murder. Doctors, nurses, paramedics, dentists, and psychiatrists are trained to save, care, and cure, but what happens when evil enters their hearts? Each episode of Murder By Medic dissects the true story of a murderous physician as told by those who witnessed the case unfold, alongside medical experts and leading criminologists who delve deep into the psyche of the killer. What drives those who take an oath to save lives to kill instead?
