Ten Days in a Mad-House is a book by American journalist Nellie Bly. It was initially published as a series of articles for the New York World; Bly later compiled the articles into a book, being published by Ian L. Munro in New York City in 1887.]
The book was based on articles written while Bly was on an undercover assignment for the New York World, feigning 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.[
The book received acclaim from critics at the time. Accumulation of her reportage and the release of her content brought her fame and led to a grand jury investigation and financial increase in the Department of Public Charities and Corrections.
