Part Three describes the discovery of phenothiazines and the advent of the neuroleptic drugs that were derived from them, such as chlorpromazine (Thorazine) by Rhône-Poulenc in France, and its purchase by Smith, Kline & French (today known as GlaxoSmithKline). The drug "produced an effect similar to frontal lobotomy", according to early reports by the company's lead investigator. Whitaker says that pharmaceutical advertising, articles published in the scientific literature, and stories in the media of "miracle drugs" transformed Thorazine into a "healing" drug.
