Michael Stone has devoted his life to studying the very worst mass murders, despots and dictators. He has made a science of psychopathic behaviour, even devising a 22-point scale for measuring evil. His special subject is serial killers but he is known to dabble in cannibals, sadists and extreme perversions. He has a soft spot for classic killers like Caligula, correlates the rise of serial murders with the Women's Movement and tells a decent 'Rabbi on a Desert Island' joke.
