Infamously known as the “Acid Bath Murderer,” John George Haigh was one of Britain’s most chilling and calculating killers of the 20th century. During the 1940s, Haigh lured his victims under the guise of business deals before murdering them and dissolving their bodies in acid, believing that without a body, he couldn’t be convicted. Behind his polite manner and well-groomed appearance was a conman turned serial killer who mistook his warped understanding of law for the perfect crime.
