In the context of The Girl Puzzle, explain the Nellie Bly's undercover work in New York of the Concept.

In 1887 Bly went to New York City and began working as the first female reporter for the New York World. She planned a ruse in which she would trick everyone into being admitted to the notoriously violent New York City Lunatic Asylum on Blackwell's Island, now Roosevelt Island, in the East River. Assuming the name Bly Brown, she began her journey at a boarding house for women and quickly convinced the house matron, the policemen sent to remove her, the judge and eventually the Asylum's overworked psychiatrists that she was insane. She experienced not only the worst of the misogynist and xenophobic assumptions by the city's bureaucracy but also the abusive treatment of those deemed mentally ill. After only a few days, she tried to convince the asylum staff that she was not ill, but it was only after the New York World sent an attorney that she was finally released. Her first article (of six), "Behind Asylum Bars," ran on Sunday, October 9, 1887, and the City aldermen allotted an extra one million dollars a year to correct the abuses that Bly eventually exposed in her full report Ten Days in a Mad-House.
