Task: Question Answering
Input (English): Passage: Notorious mob boss James "Lucky" Lombardi looks back upon his life and career on the night of his execution.
The flashbacks picks up when Lucky, born and raised on the Balkan Peninsula, tries to marry into money and goes to the U.S. to find himself a wealthy bride. He has no luck, despite his name, and instead makes an attempt to bluff his way forward, pretending to be count De Kloven, a rich aristocrat.
As De Kloven, Lucky gets hired to escort the prominent socialite Mrs. Lola Morgan, but quits when she wants him to be her lover. Instead he tries a new disguise, as Rudolph Von Hertsen, and gets involved in another racket with a Dr. J.M. Randall, performing abortions and selling unwanted babies.
When the racket is disclosed, Lucky moves on to the business of pimping young women  into prostitution. He goes as far as to trick naive young women into laying their lives in his hands, selling them as sex-slaves, thus entering into the business of white slavery. He soon becomes the head of such an organization.
His right-arm man, Nick goes to lengths to get new merchandise for the business, and kidnaps Dorothy, a young, blonde schoolgirl. The election of a new ambitious district attorney causes Lucky problems, but he refuses to slow down.
Lucky falls in love with a beautiful woman named Lois, but his affections are not returned, and she has to run for her life from his long lawless arms, with the help of one of Lucky's more goodhearted men, Harry. When Lucky discovers what Harry has done he has him killed, and is ultimately arrested and convicted of murder. The new district attorney manages to get him sentenced to death.
We return from the flashbacks to present time, where Lucky has learned his lesson: that crime doesn't pay. 
Question: What is the nickname of the person who pretends to be a rich aristocrat?
Output (English): Lucky.
