Nicky Mainello was a longtime Colombo Family soldier who served as a close aide to boss Joseph Colombo. In fact, Nicky was so close to the boss that the FBI took a keen interest in his activities and their relationship. Mainello had a long arrest record and was known to be very active as a Brooklyn gambler, numbers racketeer and bookmaker. But beyond being an avid gambler and the boss’ aide-de-camp, Nicky was a very diverse and ambitious hood, which eventually brought even more trouble his way. *Newly Revised and Expanded*
