John George Haigh was a seemingly respectable middle-class man in 1940s England, working mundane jobs in advertising and finance. What many people would later discover, however, was that Haigh’s humdrum but charming veneer hid the heart of a ruthless serial killer who would target wealthy friends and acquaintances, steal their money, then kill them and dissolve their remains in barrels of sulfuric acid, thus earning him the nickname The Acid Bath Murderer. Haigh was convicted of six slayings, though he claimed to have killed more. Dip into the horror of this true crime saga on a bitter and brutal episode 313.
