Reggie and Ronnie Kray ruled Londons 1960s gangland with a ruthless-ness and viciousness that shocks, even today. Building an empire of organised crime on a scale never done before or since, the brothers swindled, extorted, terrorised and brutally murdered. In this classic account, John Pearson explores the strange relationship that bound the twins together, and charts their gruesome career to their eventual downfall and imprisonment for life.
