The Profession of Violence - John Pearson

Rereading this book many years later I can't help but feel that Reggie Kray might have been quite a successful business man without the need to resort to crime in order to achieve what he felt was important in life, wealth and power. However he was the second half of a demented twin, and Ronnie's life was always going to end in sadness and violence. Reggie choose to support his brother and together they built an empire of crime which was doomed to disaster as the antics of the Krays became more violent and bizarre. Added to this mix we have the highly intelligent Inspector "Nipper" Read determined to see the bad guys brought to justice and peace restored to the streets of London.
