Ten days in a mad-house.

By newspaper reporter Nellie Bly, this book was initially published as a series of articles for the New York World newspaper. The book collected Bly's reportage 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.  "The book's graphic depiction of conditions at the asylum caused a sensation which brought Bly lasting fame and prompted a grand jury to launch its own investigation with Bly assisting. The jury's report resulted in an $850,000 increase in the budget of the Department of Public Charities and Corrections. The grand jury also made sure that future examinations were more thorough so that only the seriously ill went to the asylum" (Wikipedia).
