it's not about British crime, but...
next year, a Dutch movie called "De Dominee" (the reverend) will be released. It's about Klaas Bruinsma, the greatest organized crime-boss Holland ever had, who was at one point even the biggest drugs-trader in the world. He is called the Reverend because he always wore long, black coats. He is known as an eligable, charming, good-looking, well-dressed and lovable Family man, despite his brutal way of doing business.
He was shot in 1991 in a hotel (in an old-fashioned set-up!)
