10 Days In A Madhouse by Nellie Bly

A daring investigative reporter feigns mental illness to be committed to a notorious 19th‑century asylum and spends ten days undercover documenting filthy conditions, overcrowding, neglect, and physical and verbal abuse by staff and patients; her vivid first‑person account exposes systemic cruelty and indifference, sparks public outrage, and helps prompt reforms in the care of the mentally ill.
