Ten Days in a Mad-House is a book by newspaper reporter Nellie Bly. It was initially published as a series of articles for the New York World. Bly later compiled the articles into a book, which was published by Ian L. Munro in New York City in 1887. The book comprised Bly's reportage for the New York World while on an undercover assignment in which she feigned insanity at a women's boarding house, so as to be involuntarily committed to an insane asylum. She then investigated the reports of brutality and neglect at the Women's Lunatic Asylum on Blackwell's Island "Since my experiences in Blackwell's Island Insane Asylum were published in the World I have received hundreds of letters in regard to it. The edition containing my story long since ran out, and I have been prevailed upon to allow it to be published in book form, to satisfy the hundreds who are yet asking for copies.I am happy to be able to state as a result of my visit to the asylum and the exposures consequent thereon, that the City of New York has appropriated $1,000,000 more per annum than ever before for the care of the insane"-Nellie Bly
