Lucky was a true illegal businessman.Wherever he went,he made business partners and established illegal enterpises.The problem was that he never could've done the big cash ammounts like in the U.S. because he was exiled.He depended on his old connections from back home.During his stay in Italy he was mainly involved in the narcotics business for example the Italian pharmaceutical company Schiaparelli case, the fake doll auction case,the alleged candy business and many more...

Ill also disagree on the statement that he was a loner, because he wasnt the only mobster who was deported to Italy.Lucky was also constantly visited by many U.S. mafiosi,including Chicago Outfit figures like Jim Emery.Theres a famous picture with the two of them in Italy.Many of the exiled Italian mafiosi went to other European cities such as Milan, Hamburg, Paris, and Marseille and together they formed international illegal enterpises. For example, the French Connection.From Europe heroin was shipped directly to New York or smuggled through Canada and Cuba.

Shortly before Lucky's death, in Spain the Federal Bureau of Narcotics arrested 3 of his heroin couriers, who were fleeing a narcotics indictment in New York.They were arrested by Spanish authorities just few days before Luciano's death and were sent back to New York to face trial. The 3 men were Vincent Mauro,Frank Caruso and Salvatore Maneri.The government submitted evidences that Lucky provided them with the travel expenses so the agents began to consider an indictment against him.Lucky knew this and he wasnt ready for another long jail term.So maybe that was one of the biggest reasons for his heart attack
