One of the more unique British serial killers, John George Haigh killed simply because he wanted more. He had an exaggerated sense of entitlement, and would seek out victims who could support his lavish lifestyle. What is most abhorrent in this true crime murder story is not that he killed six people, but rather what he did with them after they were dead. Newspapers and tabloids would shout out headlines of John being a "vampire", a man with a blood lust who drank the blood of those he killed. But was he really a vampire? Or was John just a very clever man?

The undoing of John Haigh came about when a missing person case quickly progressed to a homicide investigation. The police officers involved stumbled across a scene so horrific, it would stay in their minds forever. You see John had learned an interesting skill while incarcerated for fraud - how to dissolve a body in sulfuric acid.
