Guardian – In a small Massachusetts town, American fund manager Harry Markopolos lived in fear of his life. For three years, he carried a Smith & Wesson revolver, checked under his car for bombs and avoided walking along dark shadowy streets. A self-confessed maths geek, he had unravelled the secret of Wall Street’s biggest conman.
A belatedly celebrated whistleblower who was ignored by everybody, Markopolos tried, umpteen times, to raise the alarm about Bernard Madoff’s $65bn (£43bn) Ponzi scheme which imploded at the end of 2008, leaving thousands of charities, hedge funds, pensioners and Hollywood stars bereft of billions of dollars. Dismissed as a misguided obsessive until Madoff’s eventual confession, he became increasingly anxious for his safety.
